how to get the values from List in C#?

static void Main(string[] args)
{
    var dataToFind = "One";
    Console.WriteLine(Find(dataToFind));
}
private static string Find(string dataToFind)
{
    IList<string> myList = new List<string>() { "One", "Two", "Three" };
    return myList.Where(item => item.Equals(dataToFind)).FirstOrDefault();
}

foreach(Modelclass rec in bizclass.Callfn())
{
string id= rec.fieldname();
}
