What you're referring to is the actual documentation of code that throws exceptions.

Read this thread that discusses this question: How to document thrown exceptions

The topic in MSDN called Exceptions and Exception Handling covers Creating and Throwing Exceptions in detail.

However, exception specifications are not part of the C# language like they are in Java. You must rely on documentation to tell the user of your API what exceptions may be thrown. You cannot force a user to handle an exception, or document it in code.
