重载

OpenStandardInput()

获取标准输入流。Acquires the standard input stream.

OpenStandardInput(Int32)

获取设置为指定缓冲区大小的标准输入流。Acquires the standard input stream, which is set to a specified buffer size.

OpenStandardInput()

获取标准输入流。Acquires the standard input stream.

public:
 static System::IO::Stream ^ OpenStandardInput();
public static System.IO.Stream OpenStandardInput ();
static member OpenStandardInput : unit -> System.IO.Stream
Public Shared Function OpenStandardInput () As Stream

返回

标准输入流。The standard input stream.

示例

下面的示例阐释了 OpenStandardInput 属性的用法。The following example illustrates the use of the OpenStandardInput property.


using namespace System;
using namespace System::Text;
using namespace System::IO;

int main()
{
   Stream^ inputStream = Console::OpenStandardInput();
   array<Byte>^bytes = gcnew array<Byte>(100);
   Console::WriteLine( "To decode, type or paste the UTF7 encoded string and press enter:" );
   Console::WriteLine( "(Example: \"M+APw-nchen ist wundervoll\")" );
   int outputLength = inputStream->Read( bytes, 0, 100 );
   array<Char>^chars = Encoding::UTF7->GetChars( bytes, 0, outputLength );
   Console::WriteLine( "Decoded string:" );
   Console::WriteLine( gcnew String( chars ) );
}

using System;
using System.Text;
using System.IO;

public class Decoder {
    public static void Main() {
        Stream inputStream = Console.OpenStandardInput();
        byte[] bytes = new byte[100];
        Console.WriteLine("To decode, type or paste the UTF7 encoded string and press enter:");
        Console.WriteLine("(Example: \"M+APw-nchen ist wundervoll\")");
        int outputLength = inputStream.Read(bytes, 0, 100);
        char[] chars = Encoding.UTF7.GetChars(bytes, 0, outputLength);
        Console.WriteLine("Decoded string:");
        Console.WriteLine(new string(chars));
    }
}
Imports System.Text
Imports System.IO

Public Class Decoder
   Public Shared Sub Main()
      Dim inputStream As Stream = Console.OpenStandardInput()
      Dim bytes(100) As Byte
      Console.WriteLine("To decode, type or paste the UTF7 encoded string and press enter:")
      Console.WriteLine("(Example: ""M+APw-nchen ist wundervoll"")")
      Dim outputLength As Integer = inputStream.Read(bytes, 0, 100)
      Dim chars As Char() = Encoding.UTF7.GetChars(bytes, 0, outputLength)
      Console.WriteLine("Decoded string:")
      Console.WriteLine(New String(chars))
   End Sub
End Class

注解

此方法可用于在 SetIn 方法更改标准输入流后重新获取它。This method can be used to reacquire the standard input stream after it has been changed by the SetIn method.

OpenStandardInput(Int32)

获取设置为指定缓冲区大小的标准输入流。Acquires the standard input stream, which is set to a specified buffer size.

public:
 static System::IO::Stream ^ OpenStandardInput(int bufferSize);
public static System.IO.Stream OpenStandardInput (int bufferSize);
static member OpenStandardInput : int -> System.IO.Stream
Public Shared Function OpenStandardInput (bufferSize As Integer) As Stream

参数

bufferSize
Int32

内部流缓冲区大小。The internal stream buffer size.

返回

标准输入流。The standard input stream.

异常

bufferSize 小于或等于零。bufferSize is less than or equal to zero.
