 property EnvDTE::TextPoint ^ StartPoint { EnvDTE::TextPoint ^ get(); };
public:
 property EnvDTE::TextPoint ^ StartPoint { EnvDTE::TextPoint ^ get(); };
[System.Runtime.InteropServices.DispId(10)]
public EnvDTE.TextPoint StartPoint { [System.Runtime.InteropServices.DispId(10)] [System.Runtime.InteropServices.TypeLibFunc(1024)] get; }
[<System.Runtime.InteropServices.DispId(10)>]
[<get: System.Runtime.InteropServices.DispId(10)>]
[<get: System.Runtime.InteropServices.TypeLibFunc(1024)>]
member this.StartPoint : EnvDTE.TextPoint

示例

[C#]

public void CodeClass2StartPointExample(DTE2 dte2)  
{  
    // Before running this example, open a code document from a project  
    // and place the insertion point within a class definition.  
    try  
    {   // Get the CodeClass2 at the insertion point.  
        TextSelection sel =   
        (TextSelection)dte2.ActiveDocument.Selection;  
        CodeClass2 cls = (CodeClass2)sel.ActivePoint.get_CodeElement(  
            vsCMElement.vsCMElementClass);  
        // Get TextPoint object at start of class.  
        TextPoint tp = cls.StartPoint;  
        // Get the line number where the class starts.  
        MessageBox.Show("The TextPoint object is located at line " +   
        tp.Line.ToString());  
    }  
    catch (Exception e)  
    {  
        MessageBox.Show(e.Message);  
    }  
}

备注

在进行了某些类型的编辑之后,代码模型元素(例如类、结构、函数、特性、委托等)的值可能变为非确定性的,这意味着不能确定它们的值始终保持不变。 有关详细信息,请参阅 "代码模型元素值在 使用代码模型查找代码时 可能发生变化" (Visual Basic) "。
