Question

I need to use method like:

DoSomething<(T)>();

But i don’t know which Type i have, only object of class Type. How can i call this method if I have only:

Type typeOfGeneric;

Answer 1

If you only have a Type specified as a Type, you’d have to build the generic method, and call it via reflection.

Type thisType = this.GetType(); // Get your current class type
MethodInfo doSomethingInfo = thisType.GetMethod("DoSomething");

MethodInfo concreteDoSomething = doSomethingInfo.MakeGenericMethod(typeOfGeneric);
concreteDoSomething.Invoke(this, null);
