c# - Get the index of item in a list given its property

Question

In MyList List<Person> there may be a Person with its Name property set to "ComTruise". I need the index of first occurrence of "ComTruise" in MyList, but not the entire Person element.

What I'm doing now is:

string myName = ComTruise;
int thatIndex = MyList.SkipWhile(p => p.Name != myName).Count();

If the list is very large, is there a more optimal way to get the index?

Answer 1

You could use FindIndex

string myName = "ComTruise";
int myIndex = MyList.FindIndex(p => p.Name == myName);

Note: FindIndex returns -1 if no item matching the conditions defined by the supplied predicate can be found in the list.
