Ability to reset IEnumerator generated using yield (C#)

Question

If I use yield instead of manually creating an IEnumerator, is it possible to implement IEnumerator.Reset?

Answer 1

This code implements an attribute that can be set to reset the enumerator. Notes:

• Unfortunately, this method of resetting won't work with multiple enumerators instances
• This doesn't reset it via the interface, but actually via setting a property either directly or through a method
• Given the complexity and the fragility, I actually wouldn't recommend this approach
• I'm actually wondering if a goto might be neater

Code:

public IEnumerator GetEnumerator(){
    do{
        this.shouldReset=FALSE;
        for (Entry e = this.ReadEntry(); e != null; e = this.ReadEntry()){
            if(self.shouldReset)break;
            else yield return e;
        }
    }
    while(self.shouldReset)
}
