how to match string in a list

I'm having a list of string like

var target = new List<string>() { "C", "C-sharp", "java" };

I'm having a string request = "C is a programming language"

This list should match with the string and should return

C,C-sharp

How can i do this?

here is the solution with linq

var m = from t in target
                where t[0] == 'C'
                select t;

Using Linq and String.Contains:

var filtered = target.Where(str => str.Contains("C"));

Another option, without Linq, is to change the existing list using List<T>.RemoveAll:

target.RemoveAll(str => !str.Contains("C"));

If you really need a regex (for something more complex), you may also use:

Regex validate = new Regex(".a.", RegexOptions.IgnoreCase);
 var filtered = target.Where(str => validate.Match(str).Success);
