C# : Get type parameter at runtime to pass into a Generic method [duplicate]

Answer 1

If you really want to invoke a generic method using a type parameter not known at compile-time, you can write something like:

typeof(YourType)
    .GetMethod("PrintGeneric2")
    .MakeGenericMethod(t)
    .Invoke(instance, new object[] { test2 } );

However, as stated by other responses, Generics might not be the best solution in your case.

Answer 2

Just call:

PrintGeneric2(test2);

The compiler will infer <t> from what you pass.

Answer 3

Generics offer Compile Time parametric polymorphism. You are trying to use them with a type specified only at Runtime. Short answer : it won't work and it has no reason to (except with reflection but that is a different beast altogether).
