using namespace System;

//void main(array<System::String ^> ^args)
void main()
{
   DateTime dateRecorded(2009, 6, 15);
   DateTime startTime(1, 1, 1, 0, 30, 0);
   TimeSpan interval(12, 0, 0);

   Double temperature1 = 52.8;
   Double temperature2 = 63.5;
   
   Console::Write("Date: {0:d}:\n   Temperature at {1:t}: {2}\n   Temperature at {3:t}: {4}\n", 
                  dateRecorded, startTime, temperature1, 
                  startTime.Add(interval), temperature2);
    Console::ReadLine();
}
// The example displays the following output:
//      Date: 6/15/2009:
//         Temperature at 12:30 AM: 52.8
//         Temperature at 12:30 PM: 63.5

備註

注意

此應用程式開發介面不符合 CLS 標準。This API is not CLS-compliant. 符合 CLS 標準的替代項目為 Console.Write(String, Object[])The CLS-compliant alternative is Console.Write(String, Object[]). C # 和 Visual Basic 編譯器會自動解析呼叫這個方法的呼叫 Console.Write(String, Object[])The C# and Visual Basic compilers automatically resolve a call to this method as a call to Console.Write(String, Object[]).

這個方法會使用 .NET 的 複合格式化功能 ,將物件的值轉換為其文字表示,並在字串中內嵌該標記法。This method uses the composite formatting feature of .NET to convert the value of an object to its text representation and embed that representation in a string. 產生的字串會寫入至輸出資料流程。The resulting string is written to the output stream.

format參數包含零或多個文字,並混合零或多個索引預留位置(稱為格式專案),其對應至這個方法的參數清單中的物件。The format parameter consists of zero or more runs of text intermixed with zero or more indexed placeholders, called format items, that correspond to an object in the parameter list of this method. 格式化進程會以對應物件值的文字表示來取代每一個格式專案。The formatting process replaces each format item with the text representation of the value of the corresponding object.

格式專案的語法是 { 索引[ , 對齊方式] [ : 格式 文字] } ,其指定強制索引、格式化文字的選擇性長度和對齊方式,以及控制對應物件值之格式規範字符的選擇性字串。The syntax of a format item is {index[,alignment][:formatString]}, which specifies a mandatory index, the optional length and alignment of the formatted text, and an optional string of format specifier characters that govern how the value of the corresponding object is formatted.

.NET 提供廣泛的格式化支援,在下列格式設定主題中有更詳細的說明。.NET provides extensive formatting support, which is described in greater detail in the following formatting topics.

給呼叫者的注意事項

這個方法會以關鍵字標記 vararg ,這表示它支援參數數目不定。This method is marked with the vararg keyword, which means that it supports a variable number of parameters. 您可以從 Visual C++ 呼叫方法,但無法從 c # 或 Visual Basic 程式碼呼叫此方法。The method can be called from Visual C++, but it cannot be called from C# or Visual Basic code. C # 和 Visual Basic 編譯器會將呼叫解析為的 Write(String, Object, Object, Object, Object) 呼叫 Write(String, Object[])The C# and Visual Basic compilers resolve calls to Write(String, Object, Object, Object, Object) as calls to Write(String, Object[]).

備註

這個方法會使用 .NET 的 複合格式化功能 ,將物件的值轉換為其文字表示,並在字串中內嵌該標記法。This method uses the composite formatting feature of .NET to convert the value of an object to its text representation and embed that representation in a string. 產生的字串會寫入至輸出資料流程。The resulting string is written to the output stream.

format參數包含零或多個文字,並混合零或多個索引預留位置(稱為格式專案),其對應至這個方法的參數清單中的物件。The format parameter consists of zero or more runs of text intermixed with zero or more indexed placeholders, called format items, that correspond to an object in the parameter list of this method. 格式化進程會以對應物件值的文字表示來取代每一個格式專案。The formatting process replaces each format item with the text representation of the value of the corresponding object.

格式專案的語法是 { 索引[ , 對齊方式] [ : 格式 文字] } ,其指定強制索引、格式化文字的選擇性長度和對齊方式,以及控制對應物件值之格式規範字符的選擇性字串。The syntax of a format item is {index[,alignment][:formatString]}, which specifies a mandatory index, the optional length and alignment of the formatted text, and an optional string of format specifier characters that govern how the value of the corresponding object is formatted.

.NET 提供廣泛的格式化支援,在下列格式設定主題中有更詳細的說明。.NET provides extensive formatting support, which is described in greater detail in the following formatting topics.

備註

這個方法會使用 .NET 的 複合格式化功能 ,將物件的值轉換為其文字表示,並在字串中內嵌該標記法。This method uses the composite formatting feature of .NET to convert the value of an object to its text representation and embed that representation in a string. 產生的字串會寫入至輸出資料流程。The resulting string is written to the output stream.

format參數包含零或多個文字,並混合零或多個索引預留位置(稱為格式專案),其對應至這個方法的參數清單中的物件。The format parameter consists of zero or more runs of text intermixed with zero or more indexed placeholders, called format items, that correspond to an object in the parameter list of this method. 格式化進程會以對應物件值的文字表示來取代每一個格式專案。The formatting process replaces each format item with the text representation of the value of the corresponding object.

格式專案的語法是 { 索引[ , 對齊方式] [ : 格式 文字] } ,其指定強制索引、格式化文字的選擇性長度和對齊方式,以及控制對應物件值之格式規範字符的選擇性字串。The syntax of a format item is {index[,alignment][:formatString]}, which specifies a mandatory index, the optional length and alignment of the formatted text, and an optional string of format specifier characters that govern how the value of the corresponding object is formatted.

.NET 提供廣泛的格式化支援,在下列格式設定主題中有更詳細的說明。.NET provides extensive formatting support, which is described in greater detail in the following formatting topics.

範例

下列範例 Person 會定義具有多個屬性的類別,這些屬性提供人員的相關資訊。The following example defines a Person class with a number of properties that provide information about a person. 它的 GetDescription 方法會傳回包含所有屬性值的陣列,但一個除外。Its GetDescription method returns an array that contains all of the property values except one. 然後,此範例會使用方法所傳回的陣列 GetDescription 來顯示 Person 物件的值。The example then uses the array returned by the GetDescription method to display the values of the Person object.

using System;

public class Person
{
   public String Name { get; set; }
   public DateTime BirthDate  { get; set; }
   public Double Height { get; set; }
   public Double Weight { get; set; }
   public Char Gender { get; set; }
   public String Remarks { get; set; }

   public object[] GetDescription()
   {
      return new object[] { Name, Gender, Height, Weight, BirthDate};
   }
}

public class Example
{
   public static void Main()
   {
      var p1 = new Person() { Name = "John", Gender = 'M',
                              BirthDate = new DateTime(1992, 5, 10),
                              Height = 73.5, Weight = 207 };
      p1.Remarks = "Client since 1/3/2012";
      Console.Write("{0}: {1}, born {4:d}  Height {2} inches, Weight {3} lbs  ",
                    p1.GetDescription());
      if (String.IsNullOrEmpty(p1.Remarks))
         Console.WriteLine();
      else
         Console.WriteLine("{1}Remarks: {0}", p1.Remarks,
                           Console.CursorLeft + p1.Remarks.Length + 10 > Console.WindowWidth ?
                              "\n   " : "");
   }
}
// The example displays the following output:
//    John: M, born 5/10/1992  Height 73.5 inches, Weight 207 lbs  Remarks: Client since 1/3/2012
Public Class Person
   Public Property Name As String
   Public Property BirthDate As DateTime
   Public Property Height As Double
   Public Property Weight As Double
   Public Property Gender As Char
   Public Property Remarks As String
   
   Public Function GetDescription() As Object()
      Return { Name, Gender, Height, Weight, BirthDate}
   End Function
End Class

Module Example
   Public Sub Main()
      Dim p1 As New Person() With { .Name = "John", .Gender = "M"c,
                                    .BirthDate = New DateTime(1992, 5, 10), 
                                    .Height = 73.5, .Weight = 207 }
      p1.Remarks = "Client since 1/3/2012"
      Console.Write("{0}: {1}, born {4:d}  Height {2} inches, Weight {3} lbs  ", 
                    p1.GetDescription())
      If String.IsNullOrEmpty(p1.Remarks) Then
         Console.WriteLine()
      Else
         Console.WriteLine("{1}Remarks: {0}", p1.Remarks,
                           If(Console.CursorLeft + p1.Remarks.Length + 10 > Console.WindowWidth,
                              vbCrLf + "   ", ""))
      End If   
   End Sub
End Module
' The example displays the following output:
'   John: M, born 5/10/1992  Height 73.5 inches, Weight 207 lbs  Remarks: Client since 1/3/2012

請注意,此範例 Write(String, Object[]) 會呼叫方法,而不是 WriteLine(String, Object[]) 方法,因為它會嘗試在 Person.Remarks 同一行上顯示內容的值。Note that the example calls the Write(String, Object[]) method rather than the WriteLine(String, Object[]) method because it attempts to display the value of the Person.Remarks property on the same line. 若要這樣做,它會檢查和屬性的值, CursorLeft WindowWidth 以判斷是否有足夠的空間可容納批註。To do this, it examines the value of the CursorLeft and WindowWidth properties to determine whether there is enough space for the remark to fit. 如果有,則會顯示該行。If there is, it displays the line. 如果沒有,則會寫入一行、縮排三個空格,並顯示批註。If not, it writes a line, indents three spaces, and displays the remark.

下列範例與第一個範例相同,不同之處在于它會提供五個專案的清單做為 arg 引數,而不是參數陣列。The following example is identical to the first, except that it supplies a five-item list as the arg argument instead of a parameter array.

using System;

public class Person
{
   public String Name { get; set; }
   public DateTime BirthDate  { get; set; }
   public Double Height { get; set; }
   public Double Weight { get; set; }

                    p1.Name, p1.Gender, p1.BirthDate, p1.Height, p1.Weight);
      if (String.IsNullOrEmpty(p1.Remarks))

備註

這個方法會使用 .NET 的 複合格式化功能 ,將物件的值轉換為其文字表示,並在字串中內嵌該標記法。This method uses the composite formatting feature of the .NET to convert the value of an object to its text representation and embed that representation in a string. 產生的字串會寫入至輸出資料流程。The resulting string is written to the output stream.

format參數包含零或多個文字,並混合零或多個索引預留位置(稱為格式專案),其對應至這個方法的參數清單中的物件。The format parameter consists of zero or more runs of text intermixed with zero or more indexed placeholders, called format items, that correspond to an object in the parameter list of this method. 格式化進程會以對應物件值的文字表示來取代每一個格式專案。The formatting process replaces each format item with the text representation of the value of the corresponding object.

格式專案的語法是 { 索引[ , 對齊方式] [ : 格式 文字] } ,其指定強制索引、格式化文字的選擇性長度和對齊方式,以及控制對應物件值之格式規範字符的選擇性字串。The syntax of a format item is {index[,alignment][:formatString]}, which specifies a mandatory index, the optional length and alignment of the formatted text, and an optional string of format specifier characters that govern how the value of the corresponding object is formatted.

.NET 提供廣泛的格式化支援,在下列格式設定主題中有更詳細的說明。.NET provides extensive formatting support, which is described in greater detail in the following formatting topics.

Decimal

要寫入的值。The value to write.

例外狀況

發生 I/O 錯誤。An I/O error occurred.

範例

在下列程式碼中,說明了如何使用 Write 方法。The following example illustrates the use of the Write method.

int main()
{
   array<String^>^lineInputArr = {"1   2.2   hello	TRUE","2   5.22   bye	FALSE","3   6.38   see ya'	TRUE"};
   for ( Int32 i = 0; i < 3; i++ )
   {
      String^ lineInput = lineInputArr->GetValue( i )->ToString();
      String^ aChar =  "\t";
      array<String^>^fields = lineInput->Split( aChar->ToCharArray() );
      Boolean isFirstField = true;
      for ( Int32 i = 0; i < fields->Length; i++ )
      {
         if ( isFirstField )
                  isFirstField = false;
         else
                  Console::Write( "," );
         
         // If the field represents a boolean, replace with a numeric representation.
         try
         {
            Console::Write( Convert::ToByte( Convert::ToBoolean( fields[ i ] ) ) );
         }
         catch ( FormatException^ ) 
         {
            Console::Write( fields[ i ] );
         }


      }
      Console::WriteLine();

   }
}

public class FormatConverter
{
    public static void Main(string[] args)
    {
        string lineInput;
        while ((lineInput = Console.ReadLine()) != null)
        {
            string[] fields = lineInput.Split(new char[] {'\t'});

                    Console.Write(item);
            }
            Console.WriteLine();
        }
    }
}
Public Class FormatConverter
   Public Shared Sub Main()
      Dim lineInput As String = Console.ReadLine()
      While Not lineInput Is Nothing
         Dim fields As String() = lineInput.Split(ControlChars.Tab)
         Dim isFirstField As Boolean = True
         For Each item As String In fields
            If isFirstField Then
               isFirstField = False
