When Visual Studio generates the XML documentation file containing the comments for the associated assembly each documented member will be identified by a unique name. You can check the rules for this ID generation at:
Processing the XML File (C# Programming Guide)
Of special interest would be the rule for methods with base type arguments, that says:
For properties and methods, if there
are arguments to the method, the
argument list enclosed in parentheses
follows. If there are no arguments, no
parentheses are present. The arguments
are separated by commas. The encoding
of each argument follows directly how
it is encoded in a .NET Framework
signature:
- Base types. Regular types (ELEMENT_TYPE_CLASS or
ELEMENT_TYPE_VALUETYPE) are
represented as the fully qualified
name of the type.
- ...
In your case would result in a ID of (M:YourNamespace.YourType.DoSomething(System.Int32)
), which could then be used in the cref
attributes.
