How to call a method overload based on closed generic type?

Question

Suppose I have three methods:

void Foo(MemoryStream v) {Console.WriteLine (\"MemoryStream\");}
void Foo(Stream v)       {Console.WriteLine (\"Stream\");}
void Fo         


        

Answer 1

This can only be done using dynamic binding, e.g. like this:

void Bar(T value)
{
    dynamic parameter = value;
    Foo(parameter); 
}

Note that dynamic dispatch uses the actual runtime type of the actual runtime object to do method dispatch, so there has to be an object. If value is null, this will not work.
