示例
Sub BasesExample(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
' Retrieve the CodeClass at the insertion point.
Dim sel As TextSelection = _
CType(dte.ActiveDocument.Selection, TextSelection)
Dim cls As CodeClass = _
CType(sel.ActivePoint.CodeElement( _
vsCMElement.vsCMElementClass), CodeClass)
' Enumerate the CodeClass's bases.
Dim bases As String = ""
Dim elem As CodeElement
For Each elem In cls.Bases
bases &= elem.FullName & vbCrLf
Next
MsgBox(cls.Name & " has the following bases:" & _
vbCrLf & vbCrLf & bases)
Catch ex As Exception
MsgBox(ex.Message)
End Try
End Sub
public void BasesExample(DTE2 dte)
{
// Before running this example, open a code document from a project
// and place the insertion point inside a class definition.
try
{
// Retrieve the CodeClass at the insertion point.
TextSelection sel =
(TextSelection)dte.ActiveDocument.Selection;
CodeClass cls =
(CodeClass)sel.ActivePoint.get_CodeElement(
vsCMElement.vsCMElementClass);
// Enumerate the CodeClass's bases.
string bases = "";
foreach (CodeElement elem in cls.Bases)
{
bases += elem.FullName + Environment.NewLine;
}
MessageBox.Show(cls.Name + " has the following bases:" +
Environment.NewLine + Environment.NewLine + bases);
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
}
注解
基数是的超级类型 CodeElements 。 对于 Visual Basic 和 Visual c #,在集合中始终只有一个元素,但当代码类型为时除外 CodeInterface 。
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) "。
