C# Array Sort(Array, Array)

Description

Array Sort(Array, Array) sorts a pair of one-dimensional Array objects (one contains the keys and the other contains the corresponding items) based on the keys in the first Array using the IComparable implementation of each key.

Syntax

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

public static void Sort(
  Array keys,
  Array items
)

Parameters

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

• keys - The one-dimensional Array that contains the keys to sort.
• items - The one-dimensional Array that contains the items that correspond to each of the keys in the keys Array.
• items - -or-
• items - null to sort only the keys Array.

Returns

Array.Sort(Array, Array) 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.

//  www .  ja  v a 2  s .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 = { "The", "A", "W", "X", "V", "Q", "!", "2", "3" };
      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.
