[C#]

    // Before running this example, open a code document from a project  
    // and place the insertion point inside a class definition.

        MessageBox.Show(cls.Name + "'s source code:" +   
            Environment.NewLine + Environment.NewLine + src);

        MessageBox.Show(ex.Message);

Remarks

The GetStartPoint and GetEndPoint methods return a TextPoint object that represents the beginning and end of a specified code element definition. The Part parameter defines the code element definition to return.

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).
