語法
'宣告
ReadOnly Property DTE As DTE
DTE DTE { get; }
property DTE^ DTE {

DTE 物件。
備註
在 Visual Studio 中,DTE 就是其他物件模型經常稱為「應用程式」的 Automation 模型根物件。
注意事項 |
---|
在特定類型的編輯之後,程式碼模型項目 (例如類別、結構、函式、屬性、委派等) 的值可能不具決定性,表示其值不一定維持相同。如需詳細資訊,請參閱使用程式碼模型探索程式碼 (Visual Basic) 的<程式碼模型項目值可以變更>一節。 |
範例
在執行這個範例之前,請先載入具有類別的專案,並在範例程式碼中插入以下程式碼行。當這個程式碼行和範例程式碼都加入之後,請按一下 [Delegate] 這一行並將插入點置於此,接著再執行這個範例。
[VisualBasic]
Delegate Sub MySubDelegate(ByVal x As Integer)
[C#]
public delegate void MySubDelegate(int x);
