Description

Array Sort(Array, IComparer) sorts the elements in a one-dimensional Array using the specified IComparer.

Syntax

Array.Sort(Array, IComparer) has the following syntax.

public static void Sort(
  Array array,
  IComparer comparer
)

Parameters

Array.Sort(Array, IComparer) has the following parameters.

• array - The one-dimensional Array to sort.
• comparer - The IComparer implementation to use when comparing elements.
• comparer - -or-
• comparer - null to use the IComparable implementation of each element.

Returns

Array.Sort(Array, IComparer) method returns

Example

The following code example shows how to sort the values in an Array using the default comparer and a custom comparer that reverses the sort order.

//  w w  w  .  j ava 2s . c o  m
using System;
using System.Collections;

class myReverserClass : IComparer  {

      // Calls CaseInsensitiveComparer.Compare with the parameters reversed. 
      int IComparer.Compare( Object x, Object y )  {
          return( (new CaseInsensitiveComparer()).Compare( y, x ) );
      }

}
   
public class SamplesArray  {
   public static void Main()  {

      String[] myArr = { "A", "C", "X", "Y", "A", "O", "W", "Q", "X" };
      IComparer myComparer = new myReverserClass();

      Array.Sort( myArr, 1, 3 );
      Array.Sort( myArr, 1, 3, myComparer );
      Array.Sort( myArr );
      Array.Sort( myArr, myComparer );
   }
}

The code above generates the following result.
