Supporting "foreach" without implementing IEnumerable
Krzysztof Cwalina wrote a post detailing how have your class support the "foreach" loop without implementing the IEnumerable interface:
- Public GetEnumerator() method that returns a type with 2 members:
- The type will have a bool MoveMext() method.
- The type will have an Current property of type object.
Example:
class Foo {
public Bar GetEnumerator() { return new Bar(); }
public struct Bar {
public bool MoveNext() {
return false;
}
public object Current {
get { return null; }
}
}
}
