How to access/call list collection items for method GetCapital()?

namespace WindowsPhoneApplication1
{
public class Countries : List<myword>
{


public Countries()
{ 
myWord latvia = new myWord("Latvia");
latvia.Capital = "Riga";
latvia.area = "65 000 sq. km";
this.Add(latvia);
myWord lithuania = new myWord("Lithuania");

lithuania.Capital = "Vilnius";
lithuania.area = "65 000 sq. km"; 
this.Add(lithuania); 
}
public string GetCapital(string theWord)
{ 
//HERE I WANT TO CALL THE ITEM E.G Latvia to get the capital using parameter which is the countryname or the listitem

string a=new myWord(theWord).Capital;
//this line above is what i tried to do but I think with this I was creating a new instance so string a returns null
return (a);
}
}

public class myWord
{
  public myWord(string name)
  {
     this.countryName = name;
  }
  public string countryName { get; set; }
  public string Capital { get; set; }
  public string area { get; set; }
}
}
</myword>

see GetCapital()

I want to get the capital using variable countryName that I will use as parameter?

If it were me, I'd create a class derived from List, and write accessor functions that used LINQ to find what you want.

public class MyList : List<MyWord>
{
    public MyWord ByCapitol(string capitol)
    {
        var country = (from item in this 
                       where item.Capitol == capitol 
                       select item).First();
        return (MyWord)country;
    }
}

And so on. BTW, your object initialization can go a lot smoother if you do something like this:

MyList myList = new MyList();
myList.Add(new MyWord(){CountryName="USA", 
                        Capitol="Washington, DC", 
                        Area="Some area info"});

You should also change your constructor and add another:

public class MyWord
{
    public MyWord() {};
    public MyWord(string name, string capitol, string area)
    {
        this.CountryName = name;
        this.Capitol = capitol;
        this.Area = area;
    }
}

That makes your oject much more versatile with regards to initialization.
