I'm wondering if there is a difference between using a Lambda expression and the delegate anonymous keyword type. Is one preferred over the other? From what I've seen both seem to be interchangeable. 

public delegate void SomeDel(string input);

public class myClass
{

   private ObjWithDel myObj;

   public myClass()
   {
    // Lambda Case
     myObj.DoDel += (val)=>{textbox1.Text = val;}

    // delegate keyword case
     myObj.DoDel += delegate(string val){textbox1.Text = val;}

   }
}

The two are different: a lambda is an "anonymous" method, it doesn't have a permanent name, whereas a Delegate is actually a reference to a method or lambda. Most of the time, lambdas will be faster than delegates, but there's cases where you can only use delegates or lambdas, not the two.

    OP is not asking about the difference between a lambda and a delegate, but rather about the difference between the two syntaxes to create an anonymus method and obtain a delegate holding it. As it happens, there is no difference at runtime. Your statement that a lambda is faster than a delegate makes no sense. – Kris Vandermotten Dec 03 '15 at 19:48
