c# - What is '1 in Collection type Name

Question

I was wondering what '1 means in Collection type name? For example: List'1, IList'1 Does anybody know what that is?

Answer 1

The backtick indicates:

The name of a generic type ends with a backtick (`) followed by digits representing the number of generic type arguments. The purpose of this name mangling is to allow compilers to support generic types with the same name but with different numbers of type parameters, occurring in the same scope.
