获取顶级扩展性对象。

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

语法

声明
ReadOnly Property DTE As DTE

DTE DTE { get; }

property DTE^ DTE {
    DTE^ get ();
}

abstract DTE : DTE

function get DTE () : DTE

属性值

类型：EnvDTE.DTE
一个 DTE 对象。

备注

在 Visual Studio 中，DTE 是自动化模型的根，其他对象模型常常将自动化模型称为“应用程序”。

备注

在进行某些类型的编辑之后，代码模型元素（如类、结构、函数、特性、委托等）的值可能是非确定性的，这意味着不能指望它们的值总是保持不变。有关更多信息，请参见使用代码模型查找代码 (Visual Basic) 中的“代码模型元素的值可能会更改”一节。

示例

Public Sub CodeClassExample(ByVal dte As DTE2) 
    ' Before running this example, open a code document from a
    ' project and place the insertion point inside a class definition.
    Try

        Dim objCodeCls As CodeClass
        objTextSel = CType(dte.ActiveDocument.Selection, TextSelection)
        objCodeCls = CType(objTextSel.ActivePoint.CodeElement(vsCMElement.vsCMElementClass), CodeClass)
        ' Add comments to CodeClass objCodeClass - notice change in code document.
        objCodeCls.Comment = "Comments for the CodeClass object."
        ' Access top-level object through the CodeClass object
        ' and return the file name of that top-level object.
        MessageBox.Show("Top-level object's filename: " + objCodeCls.DTE.FileName)
        ' Get the language used to code the CodeClass object - returns a GUID.
