[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 =

        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).
