CodeClass2::Bases Property

Visual Studio 2015

Gets a collection of classes from which this code class derives.

Namespace: EnvDTE80
Assembly: EnvDTE80 (in EnvDTE80.dll)

Syntax

property CodeElements^ Bases {
	CodeElements^ get();
}

Property Value

Type: EnvDTE::CodeElements^

A CodeElements collection.

Implements

CodeClass::Bases

Remarks

Bases are super types of CodeElements. For Visual Basic and Visual C#, there is always only one element in the collection except when the code type is a CodeInterface or CodeInterface2.

Note
The values of code model elements such as classes, structs, functions, attributes, delegates, and so forth can be non-deterministic after making certain kinds of edits, meaning that their values cannot be relied upon to always remain the same. For more information, see the section Code Model Element Values Can Change in Discovering Code by Using the Code Model (Visual Basic).

Examples

[Visual Basic]

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 CodeClass2 = _
            CType(sel.ActivePoint.CodeElement( _
            vsCMElement.vsCMElementClass), CodeClass2)

        ' Enumerate the CodeClass's bases.
        Dim bases As String = ""
        Dim elem As CodeElement2
        For Each elem In cls.Bases
            bases &= elem.FullName & vbCrLf
        Next

        MsgBox(cls.Name & " has the following bases:" & _
            vbCrLf & vbCrLf & bases)
    Catch ex As System.Exception
        MsgBox(ex.Message)
    End Try
End Sub
