Remarks

This type is enumerable because it inherits from IEnumerable<T>.

The extension methods ThenBy and ThenByDescending operate on objects of type IOrderedEnumerable<TElement>. An object of type IOrderedEnumerable<TElement> can be obtained by calling one of the primary sort methods, OrderBy or OrderByDescending, which return an IOrderedEnumerable<TElement>. ThenBy and ThenByDescending, the subordinate sort methods, in turn also return an object of type IOrderedEnumerable<TElement>. This design allows for any number of consecutive calls to ThenBy or ThenByDescending, where each call performs a subordinate ordering on the sorted data returned from the previous call.

Examples

The following example demonstrates how to perform a primary and secondary ordering on an array of strings. It also demonstrates that the resulting IOrderedEnumerable<TElement> is enumerable.

      ' Create an array of strings to sort.
      Dim fruits() As String = _
          {"apricot", "orange", "banana", "mango", "apple", "grape", "strawberry"}

      ' Sort the strings first by their length and then alphabetically by passing the identity selector function.
      Dim sortedFruits1 As IOrderedEnumerable(Of String) = _
          fruits.OrderBy(Function(fruit) fruit.Length).ThenBy(Function(fruit) fruit)

      Dim output As New System.Text.StringBuilder
      ' Output the resulting sequence of strings.
      For Each fruit As String In sortedFruits1
         output.AppendLine(fruit)
      Next

      ' Display the results.
      outputBlock.Text &= output.ToString() & vbCrLf

      ' This code produces the following output:
      '
      ' apple
      ' grape
      ' mango
      ' banana
      ' orange
      ' apricot
      ' strawberry

      // Create an array of strings to sort.
      string[] fruits = { "apricot", "orange", "banana", "mango", "apple", "grape", "strawberry" };

      // Sort the strings first by their length and then alphabetically
      // by passing the identity selector function.
      IOrderedEnumerable<string> sortedFruits1 =
          fruits.OrderBy(fruit => fruit.Length).ThenBy(fruit => fruit);

      // Output the resulting sequence of strings.
      foreach (string fruit in sortedFruits1)
         outputBlock.Text += fruit + "\n";

      // This code produces the following output:
      //
      // apple
      // grape
      // mango
      // banana
      // orange
      // apricot
      // strawberry
