Cannot step into a method returning IEnumerable?

Question

I have a method that returns an IEnumerable like this..

public virtual IEnumerable ToPages(){
  // foreach logic
  yield return pages;

  // more         


        

Answer 1

Your enumerable method will only execute once you actually try to access the members.

This is called "Deferred Execution" (see http://blogs.msdn.com/b/charlie/archive/2007/12/09/deferred-execution.aspx)

Try actually accessing the IEnumerable which is returned, or just call;

var p = obj.ToPages().ToList();
