範例

下列範例示範如何讀取資料,並將資料寫入至標準輸入和輸出資料流。The following example demonstrates how to read data from, and write data to, the standard input and output streams. 請注意這些資料流,可以使用重新導向SetInSetOut方法。Note that these streams can be redirected by using the SetIn and SetOut methods.

using namespace System;

int main()
{
   Console::Write( L"Hello " );
   Console::WriteLine( L"World!" );
   Console::Write( L"Enter your name: " );
   String^ name = Console::ReadLine();
   Console::Write( L"Good day, " );
   Console::Write( name );
   Console::WriteLine( L"!" );
}
// The example displays output similar to the following:
//       Hello World!
//       Enter your name: James
//       Good day, James!
using System;

public class Example {
    public static void Main() 
    {
        Console.Write("Hello ");
        Console.WriteLine("World!");
        Console.Write("Enter your name: ");
        String name = Console.ReadLine();
        Console.Write("Good day, ");
        Console.Write(name);
        Console.WriteLine("!");
    }
}
// The example displays output similar to the following:
//       Hello World!
//       Enter your name: James
//       Good day, James!
Public Class Example
    Public Shared Sub Main()
        Console.Write("Hello ")
        Console.WriteLine("World!")
        Console.Write("Enter your name: ")
        Dim name As String = Console.ReadLine()
        Console.Write("Good day, ")
        Console.Write(name)
        Console.WriteLine("!")
    End Sub
End Class 
' The example displays output similar to the following:
'        Hello World!
'        Enter your name: James
'        Good day, James!

備註

主控台是作業系統視窗,其中使用者互動與作業系統,或在以文字為基礎的主控台應用程式透過電腦鍵盤的文字輸入,以及讀取電腦的終端機中的文字輸出。The console is an operating system window where users interact with the operating system or with a text-based console application by entering text input through the computer keyboard, and by reading text output from the computer terminal. 比方說,在 Windows 作業系統中,主控台會呼叫 [命令提示字元] 視窗,並接受 MS-DOS 命令。For example, in the Windows operating system, the console is called the Command Prompt window and accepts MS-DOS commands. Console類別會提供讀取字元,並將字元寫入至主控台應用程式中的基本支援。The Console class provides basic support for applications that read characters from, and write characters to, the console.

如需開發資訊Console類別,請參閱下列各節:For information about developing with the Console class, see the following sections:

主控台 I/O 資料流Console I/O Streams

作業系統的主控台應用程式啟動時,自動將使用主控台三種 I/O 資料流: 標準輸入資料流、 標準輸出資料流和標準錯誤輸出資料流。When a console application starts, the operating system automatically associates three I/O streams with the console: standard input stream, standard output stream, and standard error output stream. 您的應用程式可以讀取標準輸入資料流; 的使用者輸入一般的資料寫入標準輸出資料流中;和標準錯誤輸出資料流寫入資料時發生錯誤。Your application can read user input from the standard input stream; write normal data to the standard output stream; and write error data to the standard error output stream. 這些資料流形式顯示給您的應用程式的值作為Console.InConsole.Out,和Console.Error屬性。These streams are presented to your application as the values of the Console.In, Console.Out, and Console.Error properties.

根據預設的值In屬性是System.IO.TextReader物件,表示鍵盤和值OutError屬性System.IO.TextWriter代表主控台視窗的物件。By default, the value of the In property is a System.IO.TextReader object that represents the keyboard, and the values of the Out and Error properties are System.IO.TextWriter objects that represent a console window. 不過,您可以設定這些屬性不代表主控台視窗或鍵盤; 的資料流例如,您可以設定這些屬性,代表檔案的資料流。However, you can set these properties to streams that do not represent the console window or keyboard; for example, you can set these properties to streams that represent files. 若要重新導向標準輸入、 標準輸出或標準錯誤資料流,呼叫Console.SetInConsole.SetOut,或Console.SetError方法,分別。To redirect the standard input, standard output, or standard error stream, call the Console.SetIn, Console.SetOut, or Console.SetError method, respectively. 使用這些資料流的 I/O 作業會同步處理,這表示多個執行緒可以讀取或寫入資料流。I/O operations that use these streams are synchronized, which means that multiple threads can read from, or write to, the streams. 這表示,方法是通常非同步作業,例如TextReader.ReadLineAsync,以同步方式執行,如果物件表示的主控台中的資料流。This means that methods that are ordinarily asynchronous, such as TextReader.ReadLineAsync, execute synchronously if the object represents a console stream.

注意

請勿使用Console類別,以自動執行的應用程式,例如伺服器應用程式中顯示輸出。Do not use the Console class to display output in unattended applications, such as server applications. 呼叫方法這類Console.WriteConsole.WriteLineGUI 應用程式中會有任何作用。Calls to methods such as Console.Write and Console.WriteLine have no effect in GUI applications.

Console 當基礎資料流導向主控台正常運作的類別成員可能會擲回例外狀況,如果資料流重新導向,例如,檔案。Console class members that work normally when the underlying stream is directed to a console might throw an exception if the stream is redirected, for example, to a file. 應用程式設定攔截System.IO.IOException例外狀況,如果您重新導向標準資料流。Program your application to catch System.IO.IOException exceptions if you redirect a standard stream. 您也可以使用IsOutputRedirectedIsInputRedirected,並IsErrorRedirected屬性,以決定是否要將標準資料流導向之前執行的作業會擲回System.IO.IOException例外狀況。You can also use the IsOutputRedirected, IsInputRedirected, and IsErrorRedirected properties to determine whether a standard stream is redirected before performing an operation that throws an System.IO.IOException exception.

可能會很有用來明確呼叫所表示的資料流物件的成員清單InOut,和Error屬性。It is sometimes useful to explicitly call the members of the stream objects represented by the In, Out, and Error properties. 例如,根據預設,Console.ReadLine方法會從標準輸入資料流讀取輸入。For example, by default, the Console.ReadLine method reads input from the standard input stream. 同樣地,Console.WriteLine方法會將資料寫入標準輸出資料流,資料後面接著預設行終止字串,也就是歸位字元和換行字元 ("\r\n")。Similarly, the Console.WriteLine method writes data to the standard output stream, and the data is followed by the default line termination string, which is a carriage return and line feed ("\r\n"). 不過,Console類別不提供對應的方法,將資料寫入標準錯誤輸出資料流或要變更寫入至該資料流的資料行終止字串的屬性。However, the Console class does not provide a corresponding method to write data to the standard error output stream, or a property to change the line termination string for data written to that stream.

您可以藉由設定來解決這個問題TextWriter.NewLine的屬性OutError到另一個行終止字串的屬性。You can solve this problem by setting the TextWriter.NewLine property of the Out or Error property to another line termination string. 例如,下列 C# 陳述式會將標準錯誤輸出資料流的終止串線設定為兩個歸位字元和換行字元序列:For example, the following C# statement sets the line termination string for the standard error output stream to two carriage return and line feed sequences:

Console.Error.NewLine = "\r\n\r\n";

然後,您可以明確呼叫WriteLine錯誤的輸出資料流物件,如下列 C# 陳述式所示的方法:You can then explicitly call the WriteLine method of the error output stream object, as in the following C# statement:

Console.Error.WriteLine();

螢幕緩衝區和主控台視窗Screen Buffer and Console Window

在主控台的兩個密切相關的功能是螢幕緩衝區而主控台視窗。Two closely related features of the console are the screen buffer and the console window. 實際讀取或寫入主控台中,所擁有的資料流的文字,但出現讀取或寫入至主控台呼叫螢幕緩衝區所擁有的區域。Text is actually read from or written to streams owned by the console, but appear to be read from or written to an area owned by the console called the screen buffer. 螢幕緩衝區的主控台中,屬性,並會組織成資料列和每個方格交集或字元儲存格,可以包含字元的資料行的矩形格線。The screen buffer is an attribute of the console, and is organized as a rectangular grid of rows and columns where each grid intersection, or character cell, can contain a character. 每個字元有它自己的前景色彩,而且每個字元儲存格有自己的背景色彩。Each character has its own foreground color, and each character cell has its own background color.

螢幕緩衝區是透過稱為主控台視窗的矩形區域檢視。The screen buffer is viewed through a rectangular region called the console window. 主控台視窗將會在主控台中; 的另一個屬性它不是主控台本身,也就是作業系統視窗。The console window is another attribute of the console; it is not the console itself, which is an operating system window. 主控台視窗排列在資料列和資料行小於或等於螢幕緩衝區的大小,是可以移至檢視的基礎螢幕緩衝區的不同區域。The console window is arranged in rows and columns, is less than or equal to the size of the screen buffer, and can be moved to view different areas of the underlying screen buffer. 如果螢幕緩衝區大於主控台視窗中,主控台將會自動顯示捲軸讓主控台視窗可以重新定位到螢幕緩衝區的區域。If the screen buffer is larger than the console window, the console automatically displays scroll bars so the console window can be repositioned over the screen buffer area.

資料指標會指出其中目前讀取或寫入文字的螢幕緩衝區位置。A cursor indicates the screen buffer position where text is currently read or written. 資料指標可以隱藏或顯示,並可變更其高度。The cursor can be hidden or made visible, and its height can be changed. 如果資料指標為可見,主控台視窗的位置是在因此資料指標永遠都是在檢視中自動移動。If the cursor is visible, the console window position is moved automatically so the cursor is always in view.

螢幕緩衝區中的字元資料格座標的來源是左上的角,且資料指標,而主控台視窗的位置會以相對於該原點。The origin for character cell coordinates in the screen buffer is the upper left corner, and the positions of the cursor and the console window are measured relative to that origin. 使用以零為起始的索引來指定位置;也就是指定為資料列 0,並做為資料行 0 最左邊的資料行的最上方的資料列。Use zero-based indexes to specify positions; that is, specify the topmost row as row 0, and the leftmost column as column 0. 資料列和資料行索引的最大值是Int16.MaxValueThe maximum value for the row and column indexes is Int16.MaxValue.

在主控台的 Unicode 支援Unicode Support for the Console

一般情況下,主控台讀取輸入,並將輸出寫入使用目前的主控台字碼頁,將系統地區設定定義預設。In general, the console reads input and writes output by using the current console code page, which the system locale defines by default. 字碼頁可以處理可用的 Unicode 字元的子集,因此如果您嘗試顯示的字元沒有對應的特定字碼頁,主控台將無法顯示所有字元,或精確地表示它們。A code page can handle only a subset of available Unicode characters, so if you try to display characters that are not mapped by a particular code page, the console won't be able to display all characters or represent them accurately. 下列範例說明此問題。The following example illustrates this problem. 它會嘗試對主控台顯示 044F u+0000 到 U + 0410年從斯拉夫字元。It tries to display the characters of the Cyrillic alphabet from U+0410 to U+044F to the console. 如果您使用主控台字碼頁 437 上的系統上執行範例,每個字元是由問號 (?),取代,因為斯拉夫語字元不會對應至字碼頁 437 則中的字元。If you run the example on a system that uses console code page 437, each character is replaced by a question mark (?), because Cyrillic characters do not map to the characters in code page 437.

using System;

public class Example
{
   public static void Main()
   {
      // Create a Char array for the modern Cyrillic alphabet, 
      // from U+0410 to U+044F.
      int nChars = 0x044F - 0x0410 + 1;
      char[] chars = new char[nChars];
      ushort codePoint = 0x0410;
      for (int ctr = 0; ctr < chars.Length; ctr++) {
        chars[ctr] = Convert.ToChar(codePoint);
        codePoint++;
      }   
         
      Console.WriteLine("Current code page: {0}\n", 
                        Console.OutputEncoding.CodePage);
      // Display the characters.
      foreach (var ch in chars) {
         Console.Write("{0}  ", ch);
         if (Console.CursorLeft >= 70) 
            Console.WriteLine();
      }
   }
}
// The example displays the following output:
//    Current code page: 437
//    
//    ?  ?  ?  ?  ?  ?  ?  ?  ?  ?  ?  ?  ?  ?  ?  ?  ?  ?  ?  ?  ?  ?  ?  ?

      ' Create a Char array for the modern Cyrillic alphabet, 
      ' from U+0410 to U+044F.
      Dim nChars As Integer = &h44F - &h0410
      Dim chars(nChars) As Char
      Dim codePoint As UInt16 = &h0410
      For ctr As Integer = 0 To chars.Length - 1
        chars(ctr) = ChrW(codePoint)
        codePoint += CType(1, UShort)
      Next   
         
      Console.WriteLine("Current code page: {0}", 
                        Console.OutputEncoding.CodePage)
      Console.WriteLine()
      ' Display the characters.
      For Each ch In chars
         Console.Write("{0}  ", ch)
         If Console.CursorLeft >= 70 Then Console.WriteLine()
      Next
   End Sub

除了支援字碼頁Console類別支援 utf-8 編碼方式和UTF8Encoding類別。In addition to supporting code pages, the Console class supports UTF-8 encoding with the UTF8Encoding class. 從.NET Framework 4.5Console類別也支援 utf-16 編碼方式和UnicodeEncoding類別。Beginning with the .NET Framework 4.5, the Console class also supports UTF-16 encoding with the UnicodeEncoding class. 若要在主控台中顯示的 Unicode 字元。To display Unicode characters to the console. 您設定OutputEncoding屬性設為UTF8EncodingUnicodeEncodingyou set the OutputEncoding property to either UTF8Encoding or UnicodeEncoding.

支援 Unicode 字元需要編碼器將特定的 Unicode 字元,辨識,而且也需要有圖像 (glyph),來呈現該字元所需的字型。Support for Unicode characters requires the encoder to recognize a particular Unicode character, and also requires a font that has the glyphs needed to render that character. 若要成功地對主控台顯示 Unicode 字元,必須設定主控台字型非點陣或 TrueType 字型,例如 Consolas 或 Lucida Console。To successfully display Unicode characters to the console, the console font must be set to a non-raster or TrueType font such as Consolas or Lucida Console. 下列範例會示範如何以程式設計方式變更字型從點陣字型 Lucida console。The following example shows how you can programmatically change the font from a raster font to Lucida Console.

不過,TrueType 字型可以顯示圖像 (glyph) 的子集。However, TrueType fonts can display only a subset of glyphs. 比方說,新細明體字型顯示只有 643 從 u+0021 到 U + FB02 大約 64,000 可用字元。For example, the Lucida Console font displays only 643 of the approximately 64,000 available characters from U+0021 to U+FB02. 若要查看其字元特定字型支援,請開啟字型在 控制台 小程式選擇尋找符號選項,然後選擇 的字型的字元集您想要檢查字型字元對應表視窗。To see which characters a particular font supports, open the Fonts applet in Control Panel, choose the Find a character option, and choose the font whose character set you'd like to examine in the Font list of the Character Map window.

Windows 使用字型連結來顯示不在特定字型中字符。Windows uses font linking to display glyphs that are not available in a particular font. 字型連結以顯示其他字元集的相關資訊,請參閱逐步的全球化:字型For information about font linking to display additional character sets, see Globalization Step-by-Step: Fonts. 連結的字型定義於登錄 HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\FontLink\SystemLink 子機碼。Linked fonts are defined in the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\FontLink\SystemLink subkey of the registry. 這個子機碼相關聯的每個項目對應的基底字型名稱,其值為字串陣列,定義字型檔案和已連結至基底字型的字型。Each entry associated with this subkey corresponds to the name of a base font, and its value is a string array that defines the font files and the fonts that are linked to the base font. 陣列的每個成員定義連結的字型,並採用下列格式字型檔名字型名稱Each member of the array defines a linked font and takes the form font-file-name,font-name. 下列範例說明如何以程式設計方式定義名為 Pmingliu 位於名為 simsun.ttc 顯示簡化 Han 字元的字型檔的連結的字型。The following example illustrates how you can programmatically define a linked font named SimSun found in a font file named simsun.ttc that displays Simplified Han characters.

在主控台的 Unicode 支援具有下列限制:Unicode support for the console has the following limitations:

  • 不支援 UTF-32 編碼。UTF-32 encoding is not supported. 唯一支援的 Unicode 編碼為 utf-8 及 utf-16,這由UTF8EncodingUnicodeEncoding類別,分別。The only supported Unicode encodings are UTF-8 and UTF-16, which are represented by the UTF8Encoding and UnicodeEncoding classes, respectively.

  • 不支援雙向輸出。Bidirectional output is not supported.

  • 顯示基本多語文字面之外的字元 (亦即,surrogate 字組) 不支援,即使它們定義在連結的字型檔案。Display of characters outside the Basic Multilingual Plane (that is, of surrogate pairs) is not supported, even if they are defined in a linked font file.

  • 不支援顯示複雜的指令碼中的字元。Display of characters in complex scripts is not supported.

  • 結合字元序列 (也就是個字元所組成的基底的字元和一個或多個組合的字元) 會顯示為不同的字元。Combining character sequences (that is, characters that consist of a base character and one or more combining characters) are displayed as separate characters. 若要解決這項限制,您可以將正規化的字串會顯示藉由呼叫String.Normalize方法,然後再將輸出傳送至主控台。To work around this limitation, you can normalize the string to be displayed by calling the String.Normalize method before sending output to the console. 在下列範例中,包含組合字元的字串排序 U + 0061 為輸出字串會正規化之前, 的兩個字元,並為單一字元之後,將會顯示到主控台的 U + 0308年String.Normalize呼叫方法。In the following example, a string that contains the combining character sequence U+0061 U+0308 is displayed to the console as two characters before the output string is normalized, and as a single character after the String.Normalize method is called.

    using System;
    using System.IO;
    
    public class Example
    {
       public static void Main()
       {
          char[] chars = { '\u0061', '\u0308' };
       
          string combining = new String(chars);
          Console.WriteLine(combining);
          
          combining = combining.Normalize();
          Console.WriteLine(combining);
       }
    }
    // The example displays the following output:
    //       a"
    //       ä
    
    Module Example
       Public Sub Main()
          Dim chars() As Char = { ChrW(&h0061), ChrW(&h0308) }
       
          Dim combining As String = New String(chars)
          Console.WriteLine(combining)
          
          combining = combining.Normalize()
          Console.WriteLine(combining)
       End Sub
    End Module
    ' The example displays the following output:
    '       a"
    '       ä
    

    請注意當正規化標準字元包括對應至特定 combining 預先撰寫的表單的 Unicode 字元序列時,才會是可行的解決方案。Note that normalization is a viable solution only if the Unicode standard for the character includes a pre-composed form that corresponds to a particular combining character sequence.

  • 如果字型提供私用區域字碼指標的圖像 (glyph),將會顯示該圖像 (glyph)。If a font provides a glyph for a code point in the private use area, that glyph will be displayed. 不過,因為私用區域中的字元都是特定應用程式,這可能不是預期的圖像 (glyph)。However, because characters in the private use area are application-specific, this may not be the expected glyph.

下列範例會顯示到主控台的 Unicode 字元的範圍。The following example displays a range of Unicode characters to the console. 此範例接受三個命令列參數: 要顯示,以顯示,以及是否要使用目前的主控台編碼範圍的結尾範圍的開頭 (false) 或 utf-16 編碼 (true)。The example accepts three command-line parameters: the start of the range to display, the end of the range to display, and whether to use the current console encoding (false) or UTF-16 encoding (true). 它會假設主控台使用 TrueType 字型。It assumes that the console is using a TrueType font.

.NET Core.NET Core 附註Notes

在桌面上,.NET Framework 中Console類別會使用所傳回的編碼GetConsoleCPGetConsoleOutputCP,這通常字碼頁編碼方式。In the .NET Framework on the desktop, the Console class uses the encoding returned by GetConsoleCP and GetConsoleOutputCP, which typically is a code page encoding. 比方說在系統文化特性是英文 (美國),字碼頁 437 上的程式碼,是依預設會使用的編碼方式。For example code, on systems whose culture is English (United States), code page 437 is the encoding that is used by default. 不過,.NET Core.NET Core可以提供可用的只有這些編碼方式的有限的子集。However, .NET Core.NET Core may make only a limited subset of these encodings available. 在這種情況,Encoding.UTF8做為主控台的預設編碼方式。Where this is the case, Encoding.UTF8 is used as the default encoding for the console.

如果您的應用程式相依於特定字碼頁編碼方式,您仍然可以在它們可執行下列之前呼叫任何Console方法:If your app depends on specific code page encodings, you can still make them available by doing the following before you call any Console methods:

  1. 您可以將 System.Text.Encoding.CodePages.dll 組件的參考加入專案。Add a reference to the System.Text.Encoding.CodePages.dll assembly to your project.

  2. 擷取EncodingProvider物件從CodePagesEncodingProvider.Instance屬性。Retrieve the EncodingProvider object from the CodePagesEncodingProvider.Instance property.

  3. 傳遞EncodingProvider物件至Encoding.RegisterProvider進行編碼的提供者所支援的其他編碼的方法。Pass the EncodingProvider object to the Encoding.RegisterProvider method to make the additional encodings supported by the encoding provider available.

Console類別會再自動使用預設系統編碼方式 」,而不 UTF8,前提是您註冊編碼提供者之前呼叫任何Console輸出方法。The Console class will then automatically use the default system encoding rather than UTF8, provided that you have registered the encoding provider before calling any Console output methods.
