C# Get all string list items split

Question

I have a List of strings with the items such-

Titanic, Leonardo Decaprio  
Mission Impossible, Tom Cruise

Is there any way such that I can get only the first substring before the comma? In above case the expected output for List<string> should be -

Titanic
Mission Impossible

@MicroVirus Not a duplicate of it. The answer I got below was the one I was looking for. — Arpit Gupta, Jun 21 '16 at 12:31
It a duplicate. The only difference is that you want to do this for every element of the list. If you can't apply the answer in that duplicate (using `Split`) with how to do that for each element of the list, then you need to really get back to the basics of learning C#. — MicroVirus, Jun 21 '16 at 12:36

You can use Split method and then using Select method get only the first part.

list.Select(x=> x.Split(',')[0]);

You can use Substring and IndexOf instead of Split

list.Select(x => x.Substring(0, x.IndexOf(',')));

If you are not sure that every string contains comma you can check it, for example this way

list.Select(x => x.Substring(0, x.IndexOf(',') > 0 ? x.IndexOf(',') : x.Length))

You will also need to call .ToList() method otherwise it will not cast the resulting list into List<string> and throw exception because resulting list would of type System.Collections.Generic.IEnumerable<string> and your's is of List<string

List<string> list = new List<string>() { "Titanic, Leonardo Decaprio", " Mission Impossible, Tom Cruise" };
list = list.Select(x => x.Split(',')[0]).ToList();
