Action: equivalent to a delegate without passing parameters. This parameter is added from Framework 3.5 to simplify the delegate call.Code: Original delegate code: Using System; Using System. Windows. forms;

Yield can be used in two forms: yield return; and yield break;They are usually used with the enumerator object ienumerable (supporting simple iteration on non-generic sets. Yield return: return the data immediately after a data is obtained. You do
