CodeClass.DTE 属性

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 objTextSel As TextSelection
        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.
        MessageBox.Show(objCodeCls.Language)
        ' Get a collection of elements contained by the CodeClass object.
        Dim members As String = "Member Elements of " + objCodeCls.Name + ": " + vbCrLf
        Dim elem As CodeElement
        For Each elem In  objCodeCls.Members
            members = members + (elem.Name + vbCrLf)
        Next elem
        MessageBox.Show(members)
    Catch ex As Exception
        MessageBox.Show(ex.Message)
    End Try
End Sub
public void CodeClassExample(DTE2 dte)
{
   // Before running this example, open a code document from a
   // project and place the insertion point inside a class definition.
   try
   {

      CodeClass objCodeCls;
      objTextSel = (TextSelection)dte.ActiveDocument.Selection;
      objCodeCls = (CodeClass)objTextSel.ActivePoint.get_CodeElement(vsCMElement.vsCMElementClass);
      // 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.
      MessageBox.Show(objCodeCls.Language);
      // Get a collection of elements contained by the CodeClass object.
      string members = "Member Elements of " + objCodeCls.Name + ": \n";
      foreach (CodeElement elem in objCodeCls.Members)
      {
         members = members + (elem.Name + "\n");
      }
      MessageBox.Show(members);
   }
   catch (Exception ex)
   {
      MessageBox.Show(ex.Message);
   }
}
