C# Check List against part of string

Question

I have a list which contains values such as:

readies action
uses action
begins to cast action

I want to compare a string to match against this list and return a boolean based on that. So for example:

string compare = "The Manipulator uses action";

To do this I have tried two different methods, the first being:

if (mylist.Contains(compare)) { //True }

and the second (with Linq):

if (mylist.Any(str => str.Contains(compare))) { //True }

The problem I'm having is both of these methods match against an extended string. What I mean by that is if compare == "uses action" the statement returns true, but if compare == "The Manipulator uses action" the statement returns false.

Any help on fixing this would be most appreciated! :)

I'm not totally following what you're looking for, so there are 2 different solutions, besed on expected outcome.

If you're only trying to match exactly the same string from within the list Any is the way to go, but you should use == instead of Contains:

if (mylist.Any(str => str == compare)) { //True }

If you'd like extended string to also match, you use Contains, but instead of calling str.Contains(compare) call compare.Contains(str):

if (mylist.Any(str => compare.Contains(str))) { //True }

Excellent. if (mylist.Any(str => compare.Contains(str))) { //True } does what I was looking for! Thanks so much.
