How can I use an expression tree to call a generic method when the Type is only known at runtime?

Question

This is something that I solved using reflection, but would like to see how to do it using expression trees.

I have a generic function:

private void DoSo         


        

Answer 1

MethodInfo.MakeGenericMethod

Then just create a delegate and call it. (not in an expression, of course ;p)

Update:

Generally, I prefer to use generic types for this, Activator.CreateInstance just requires less work. All depends on your situation though.
