How to get the index of an item in a list in a single step?

Question

How can I find the index of an item in a list without looping through it?

Currently this doesn\'t look very nice - searching through the list for the same item twice

Answer 1

If you don't want to use LINQ, then:

int index;
for (int i = 0; i < myList.Count; i++)
{
    if (myList[i].Prop == oProp)
    {
       index = i;
       break;
    }
}

this way you are iterating list only once.
