Console.Out 屬性

定義

取得標準輸出資料流。

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,代表標準輸出資料流。

範例

下列範例會 Out 使用 屬性,將包含應用程式目前目錄中檔案名稱的陣列顯示至標準輸出裝置。 然後,它會將標準輸出設定為名為 Files.txt 的檔案,並將陣列元素列出至檔案。 最後,它會將輸出設定為標準輸出資料流程,並再次將陣列元素顯示至標準輸出裝置。

備註

此屬性預設會設定為標準輸出資料流程。 這個屬性可以使用 方法設定為另一個資料流程 SetOut

請注意,對 方法的 Console.Out.WriteLine 呼叫相當於呼叫對應的 WriteLine 方法。
