C# orderby Keyword

Use the orderby leyword to sort a list in ascending or descending order.

The following is the list −

List<string> myList = new List<string>();
myList.Add("truck");
myList.Add("bus");
myList.Add("bicycle");
myList.Add("motorbike");

Now let us sort the list in descending order −

myLen = from element in myList
orderby element.Length descending
select element;

Here is the complete code −

Example

using System;
using System.Collections.Generic;
using System.Linq;
class Demo {
   static void Main() {
      List<string> myList = new List<string>();
      myList.Add("truck");
      myList.Add("bus");
      myList.Add("bicycle");
      myList.Add("motorbike");
      var myLen = from element in myList
      orderby element.Length
      select element;
      Console.WriteLine("Ascending order...");
      foreach (string str in myLen){
         Console.WriteLine(str);
      }
      myLen = from element in myList
      orderby element.Length descending
      select element;
      Console.WriteLine("Descending order...");
      foreach (string str in myLen) {
         Console.WriteLine(str);
      }
   }
}

Output
