Console.Out 屬性

定義

命名空間:

System

組件:

netstandard.dll, System.Console.dll

來源:

Console.cs

會接收標準輸出流。

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

屬性值

TextWriter

A TextWriter 代表標準輸出流。

範例

以下範例利用該 Out 特性，將包含應用程式目前目錄中檔案名稱的陣列顯示給標準輸出裝置。 接著它將標準輸出設定為名為 Files.txt 的檔案，並列出該檔案的陣列元素。 最後，它將輸出設定為標準輸出串流，並再次將陣列元素顯示給標準輸出裝置。

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));
   }
}

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

      Console.Out.WriteLine()

      ' Redirect output to a file named Files.txt and write file list.

      ' 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

備註

此屬性預設設為標準輸出串流。 此屬性可透過 方法 SetOut 設定至另一串流。

請注意，呼叫 Console.Out.WriteLine 方法等同於呼叫對應 WriteLine 方法。
