Get value from anonymous type

Question

I have a method as following:

public void MyMethod(object obj){

  // implement

}

And I call it like this:

MyMethod(new { mypa         


        

Answer 1

Well, you could use dynamic typing if you're using C# 4:

public void MyMethod(object obj) {
    dynamic d = obj;
    Console.WriteLine(d.myparam);
}

It does beg the question of why you're not using a named type though. Anonymous types aren't really designed to be shared among different methods like this.

EDIT: Note that if this is in a different assembly to the original code creating the object, you'll need to use [InternalsVisibleTo] as anonymous types are internal.
