Remarks

This method is useful when there are type names specified as strings in formats like a data support XML file, and these type names cannot be automatically resolved (or would be resolved incorrectly) by the CLR’s GetType method. One use of this method is to expand an unspecified namespace. (For example, if the string is "MyType", it might get expanded to "Company.Product.MyType" before the CLR resolves it.)

This method is provided to shorten a provider’s specification of type names, which can help reduce duplication of elements, like a common namespace, throughout the code base.

The base class implementation tries to locate a comma separating the type name from its qualifying assembly, and, if found, calls the GetAssembly method with the assembly qualifier and then, if found, tries to retrieve the type from this assembly. Otherwise it calls GetAssembly with an empty string and, if found, tries to get the type from this assembly. Finally, if the type is still not found, it calls the standard GetType method and returns the result of this call.
