Finding comma separated Strings in List<String>

Question

I have a string list and I have a comma separated String.

I would like to do something like:

StringList.Contains(CommaSeparatedStrings);

So for example I have a list like:

StringList.Add(Admin);
StringList.Add(Nurse);
StringList.Add(Cook);

CommaSeparatedStrings = "Admin,Nurse";

So the above mentioned function should return true.

You have to use String.Split to get a collection that you can use:

bool containsAny = StringList.Intersect(CommaSeparatedStrings.Split(',')).Any();

If you want to know if all items (not only at least one) are contained:

bool containsAll = !CommaSeparatedStrings.Split(',').Except(StringList).Any();

or with Enumerable.All which seems to be the most readable way:

bool containsAll = CommaSeparatedStrings.Split(',').All(StringList.Contains);

check if CommaSeperatedStrings splitted - StringList contains any value

bool contains = !CommaSeperatedStrings.Split(',').Except(StringList).Any()
