public class MainClass{
public static void Main(String[] argv){
System.Collections.ArrayList fruits = new System.Collections.ArrayList();
fruits.Add("mango");
fruits.Add("apple");
fruits.Add("lemon");
IEnumerable<string> query = fruits.Cast<string>().OrderBy(fruit => fruit).Select(fruit => fruit);
foreach (string fruit in query)
{
Console.WriteLine(fruit);
}
}
}
The code above generates the following result.
