Best way to check for string in comma-delimited list with .NET?

Question

I\'m reading a comma-delimited list of strings from a config file. I need to check whether another string is in that list. For example:

\"apple,banana,cheese\"

Answer 1

Another way might be to try using

bool contains = new List("apple,banana,cheese".Split(',')).Contains("apple");
//or
bool b = "apple,banana,cheese".Split(',').Contains("apple");

List< T>.Contains Method

String.Split Method

Enumerable.Contains Method
