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

        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

[C#]

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;  
        CodeClass2 cls =   
            (CodeClass)sel.ActivePoint.get_CodeElement2(  
            vsCMElement.vsCMElementClass);  

        // Enumerate the CodeClass's bases.  
        string bases = "";  
        foreach (CodeElement2 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);  
    }  
}

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).
