IEnumerator Reset Error

[RoguePoet01]

Hi,

I'm new to this and I can't figure it out.

This example was given to me in a book:

using System;
using System.Collections;

// LINKED LIST ENUMERATOR
public class LinkedListEnumerator : IEnumerator {

private _node m_current = null;
private _node m_begin = null;
private bool m_last = false;

public LinkedListEnumerator( _node n ) { m_current = m_begin = n; }

...

}

But when I try to compile the snippit, I get this error:

'LinkedListEnumerator' does not implement interface member 'System.Collections.IEnumerator.Reset()'

Any ideas?

Thanks.

Found it:

"IEnumerator is an interface which has three functions MoveNext, Reset and Current and xxx has to implement all of them to remove the compiler errors"

The reset code was missing:

public void Reset() {
m_current = m_begin;
m_last = false;
}
