Making By-ref and Array Types...Easily!
I just found out something tonight that was introduced in .NET 2.0. Before 2.0, if you wanted to create a type that was by-ref or an array, you had to do this:
Type byRefType = Type.GetType("System.String&");
Type arrayType = Type.GetType("System.String[]");
Type arrayByRefType = Type.GetType("System.String[]&");
That always felt ugly to me. However, now you can use the MakeByRefType() and MakeArrayType() methods so you don't have to worry about messing up the string definition:
Type byRefType = typeof(string).MakeByRefType();
Type arrayType = typeof(string).MakeArrayType();
Type arrayByRefType = typeof(string).MakeArrayType().MakeByRefType();
There's also a MakePointerType() for completeness sake. Cool stuff!
