Find element in List<> that contains a value

I have a

List<MyClass> MyList
where

public class MyClass
{
public string name { get; set; }
public string value { get; set; }
}


Given a name, I'd like to get the corresponding value. I have it currently implemented as:

MyList[MyList.FindIndex(item => String.Compare(item.name, "foo", 0) == 0)].value


Is there a cleaner way to do this?

Answer

Either use LINQ:

var value = MyList.First(item => item.name == "foo").value;

(This will just find the first match, of course. There are lots of options around this.)

Or use Find instead of FindIndex:

var value = MyList.Find(item => item.name == "foo").value;

I'd strongly suggest using LINQ though - it's a much more idiomatic approach these days.

(I'd also suggest following the .NET naming conventions.)
