获取标准输出流。

public:
 static property System::IO::TextWriter ^ Out { System::IO::TextWriter ^ get(); };
public static System.IO.TextWriter Out { get; }
static member Out : System.IO.TextWriter
Public Shared ReadOnly Property Out As TextWriter

属性值

TextWriter

表示标准输出流的 TextWriter。

示例

以下示例使用 Out 属性向标准输出设备显示包含应用程序当前目录中文件名的数组。 然后，它将标准输出设置为名为 Files.txt 的文件，并将数组元素列出到该文件。 最后，它将输出设置为标准输出流，并再次向标准输出设备显示数组元素。

using System;
using System.IO;

public class Example
{
   public static void Main()
   {
      // Get all files in the current directory.
      string[] files = Directory.GetFiles(".");
      Array.Sort(files);

      // Display the files to the current output source to the console.
      Console.Out.WriteLine("First display of filenames to the console:");
      Array.ForEach(files, s => Console.Out.WriteLine(s));
      Console.Out.WriteLine();

      // Redirect output to a file named Files.txt and write file list.
      StreamWriter sw = new StreamWriter(@".\Files.txt");
      sw.AutoFlush = true;
      Console.SetOut(sw);
      Console.Out.WriteLine("Display filenames to a file:");
      Array.ForEach(files, s => Console.Out.WriteLine(s));
      Console.Out.WriteLine();

      // Close previous output stream and redirect output to standard output.
      Console.Out.Close();
      sw = new StreamWriter(Console.OpenStandardOutput());
      sw.AutoFlush = true;
      Console.SetOut(sw);

      // Display the files to the current output source to the console.
      Console.Out.WriteLine("Second display of filenames to the console:");
      Array.ForEach(files, s => Console.Out.WriteLine(s));
   }
}

open System.IO

// Get all files in the current directory.
let files = 
    Directory.GetFiles "."
    |> Array.sort

// Display the files to the current output source to the console.

Imports System.IO

Module Example
   Public Sub Main()
      ' Get all files in the current directory.
      Dim files() As String = Directory.GetFiles(".")
      Array.Sort(files)
      
      ' Display the files to the current output source to the console.
      Console.WriteLine("First display of filenames to the console:")
      Array.ForEach(files, Function(s) WriteOutput(s))   
      Console.Out.WriteLine()

      ' Redirect output to a file named Files.txt and write file list.
      Dim sw As StreamWriter = New StreamWriter(".\Files.txt")
      sw.AutoFlush = True
      Console.SetOut(sw)
      Console.Out.WriteLine("Display filenames to a file:")
      Array.ForEach(files, Function(s) WriteOutput(s))
      Console.Out.WriteLine()

      ' Close previous output stream and redirect output to standard output.
      Console.Out.Close()
      sw = New StreamWriter(Console.OpenStandardOutput())
      sw.AutoFlush = True
      Console.SetOut(sw)
           
      ' Display the files to the current output source to the console.
      Console.Out.WriteLine("Second display of filenames to the console:")
      Array.ForEach(files, Function(s) WriteOutput(s))   
   End Sub
   
   Private Function WriteOutput(s As String) As Boolean
      Console.Out.WriteLine(s)
      Return True
   End Function
End Module

注解

默认情况下，此属性设置为标准输出流。 可以使用 方法将此属性设置为另一个流 SetOut 。

请注意，对 Console.Out.WriteLine 方法的调用等效于对相应 WriteLine 方法的调用。
