Access type parameters of generic type

Hello,

suppose I have a generic type MyCollection<TX, TY, TZ> in C# 3.5. Now, I want to use as a type parameter in another generic type which needs just one type param, e.g. OtherTYpe<TA> where TA:MyCollection. How can I refer to TA.TX, TA.TY, TA.TZ inside the template of OtherTYpe? I dislike the idea of declaring OtherType<TA, TX, TY, TZ> when TX, TY, TZ are already present in TA.

Also, is there something like the C typedef keyword, so that I can easily name MyCollection<TX, TY, TZ> as MyXYZCollection without having to create a descendant type? I.e.
typedef MyCollection<TX, TY, TZ> MyXYZCollection

Thanks in advance

Thanks, kaufmed. It's a very helpful solution. However, it's not exactly what I wanted since this is valid just inside the file in which it is declared. The C/C++ typedef is valid in any file into which I include that header. So is there any way to create a global alias valid throughout an entire ASP.NET application?
