Overloading function call operator in C#

Question

Is it possible to overload the default function operator (the () operator) in C#? If so - how? If not, is there a workaround to create a similar affect?

Thanks,

Yes, this can be absolutely be done with the dynamic type (more info found here).

using System.Dynamic.DynamicObject

class A : DynamicObject 
{
    private int val;

    A(int myvalue)
    {
        this.val = myvalue;
    }

    public override bool TryInvoke(InvokeBinder binder, object[] args, out object result) {
        result = this.val;
        return true;
    }
}

...

dynamic a = new A(5);
Console.Write(a());

The dynamic type means that the type is assumed entirely at runtime allowing for a greater flexability to almost every interaction with the object.

I have assumed you meant to use a rather than A in the Console.Write line.
