Can an anonymous method in C# call itself?

Question

I have the following code:

class myClass
{
private delegate string myDelegate(Object bj);

protected void method()
   {
   myDelegate build = delegate(Object         


        

Answer 1

If you use Y, your function becomes a parameter to the function itself, so that you can call it recursively:

class myClass {
  private delegate string myDelegate(Object bj);
  protected void method() {
    myDelegate build = delegate(Object obj) {
      // f is the function itself, which is passed into the function
      return Functional.Y(f => bj => { 
        var letters = string.Empty;
        if (someCondition)
          return f(some_obj); // use f
        else return string.Empty;

      })(obj);
    };
  }
}

public static class Functional {
  public delegate Func Recursive(Recursive r);
  public static Func Y(Func, Func> f) {
    Recursive rec = r => a => f(r(r))(a);
    return rec(rec);
  }
}
