C# feature request: implement interfaces on anonymous types

Question

I am wondering what it would take to make something like this work:

using System;

class Program
{
    static void Main()
    {
        var f = new IFoo { 
              


        

Answer 1

Interesting idea, I'd be a little concerned that even if it could be done it might get confusing. E.g. when defining a property with non-trivial setters and getters, or how to disambiguate Foo if the the declaring type also contained a property called Foo.

I wonder if this would be easier in a more dynamic language, or even with the dynamic type and DLR in C# 4.0?

Perhaps today in C# some of the intent could be achieved with lambdas:

void Main() {
    var foo = new Foo();
    foo.Bar = "bar";
    foo.Print = () => Console.WriteLine(foo.Bar);
    foo.Print();
}


class Foo : IFoo {
    public String Bar { get; set; }    
    public Action Print {get;set;}
}
