命名空间：  EnvDTE80
程序集：  EnvDTE80（在 EnvDTE80.dll 中）

语法

声明
ReadOnly Property StartPoint As TextPoint

TextPoint StartPoint { get; }

property TextPoint^ StartPoint {
    TextPoint^ get ();
}

abstract StartPoint : TextPoint

function get StartPoint () : TextPoint

属性值

类型：EnvDTE.TextPoint
一个 TextPoint 对象。

示例

此示例打开一个文本文档，然后使用文本窗格的 StartPoint 属性，在消息框中显示有关文本窗格内文本起点和终点的信息。 有关如何作为外接程序运行此示例的更多信息，请参见 如何：编译和运行自动化对象模型代码示例。
