Find element in List<> that contains a value

Question

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 1

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.)

Answer 2

You can use the Where to filter and Select to get the desired value.

MyList.Where(i=>i.name == yourName).Select(j=>j.value);
