Remarks

DocComment works differently with Visual Basic and Visual C++ than it does with Visual C#. Visual C# surrounds the XML returned by DocComment with <doc> tags, but Visual Basic and Visual C++ do not. For example, Visual Basic and Visual C++ return:

<summary>  
</summary>  
<value>  
</value>  

Whereas Visual C# returns:

<doc>  
  <summary>  
  </summary>  
  <value>  
  </value>  
</doc>  

As a result, you need to keep the programming language in mind and adjust your handling of the resultant XML accordingly.

DocComment returns the special documentation comment or attribute if there is one in the code. If the language implementing the code model does not have a documentation comment mechanism, or if there is none associated with the code element, then DocComment returns an empty string.

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).
