Or the equivalent C# code, private static string <Main>b__2(string x) { return x; } The CLR will use this as input parameter to the MulticastDelegateclass and create another instance of the MulticastDelegate type. It will then use the iterator instantiated from the Step 2 and delegate in...
In the example above, variable value is of an anonymous type whose definition is equivalent to the following pseudo-C#: Copy internal class ??? { string _Name; int _Age; bool _CanCode; public string Name { get { return _Name; } set { _Name = value; } } public int Age{ get {...
