interface as argument or generic method with where - what is the difference?

Question

Is any difference between :

public void Method1(class1 c, T obj) where T:Imyinterface

And

public void Method2(clas         


        

Answer 1

There is no big difference for void methods.

public void Method1(class1 c, T obj) where T : Imyinterface

equals to

public void Method2(class1 c, Imyinterface obj, Type t)

where t must be Imyinterface.

So if you need to pass some Type to your method, and you need to apply some constraints to that Type at compile-time, use the generic method.
