Getting an item in a list

Question

I have the following list item

public List<Configuration> Configurations
{
    get;
    set;
}

 public class Configuration
  {
    public string Name
     {
       get;
       set;
     }
    public string Value
      {
       get;
       set;
     }
 }

How can I pull an item in configuration where name = value?

For example: lets say I have 100 configuration objects in that list.

How can I get : Configurations.name["myConfig"]

Something like that?

UPDATE: Solution for .net v2 please

Answer 1

Using the List<T>.Find method in C# 3.0:

var config = Configurations.Find(item => item.Name == "myConfig");

In C# 2.0 / .NET 2.0 you can use something like the following (syntax could be slightly off as I haven't written delegates in this way in quite a long time...):

Configuration config = Configurations.Find(
    delegate(Configuration item) { return item.Name == "myConfig"; });

It seems like what you really want is a Dictionary (http://msdn.microsoft.com/en-us/library/xfhwa508.aspx).

Dictionaries are specifically designed to map key-value pairs and will give you much better performance for lookups than a List would.
