return obj.IndexOf(value, 0);
}
public static int IndexOf<T>(this IEnumerable<T> obj, T value, int start)
{
if (start >= obj.Count()) return -1;
if (start < 0) throw new IndexOutOfRangeException("start must be a non-negative integer");
for (int i = start; i < obj.Count(); ++i)
{
if (value.Equals(obj.ElementAt(i))) return i;
}
return -1;
}
Example
var i = new Collection<int>{0,1,2,3,4,5,6,7};
int first = i.IndexOf(0);
int second = i.IndexOf(0,1);
