Never heard of GetHash. I've got 5000+ Web pages of documentation mostly just on the .NET Framework, am betting my start up on .NET, ASP.NET, ADO.NET, and Visual Basic .NET, and have yet to encounter GetHash. From the mnemonics of the naming, a guess is that GetHash has to do with hashing. Well, mostly I don't like hashing and prefer extendible hashing, AVL trees, red-black trees, B-trees, heaps, etc. Typically, for a class in the .NET Framework, to use it for the first time have to find a dozen or so Web pages at MSDN and learn them: For me that means download, index, abstract, and read the pages, look at the sample code, and maybe write some minimal code to exercise the class. Yes, being clear on call by reference versus call by value is important but also quite elementary. Basically, all aggregates are to be call by reference; simple numeric constancts are commonly call by value.
