C# Array Sort(TKey[], TValue[], Int32, Int32)

Description

Array Sort (TKey[], TValue[], Int32, Int32) sorts a range of elements in a pair of Array objects (one contains the keys and the other contains the corresponding items) based on the keys in the first Array using the IComparable generic interface implementation of each key.

Syntax

Array.Sort<TKey, TValue>(TKey[], TValue[], Int32, Int32) has the following syntax.

public static void Sort<TKey, TValue>(
  TKey[] keys,//from   ww  w.j ava  2  s .  c om
  TValue[] items,
  int index,
  int length
)

Parameters

Array.Sort<TKey, TValue>(TKey[], TValue[], Int32, Int32) has the following parameters.

• TKey - The type of the elements of the key array.
• TValue - The type of the elements of the items array.
• keys - The one-dimensional, zero-based Array that contains the keys to sort.
• items - The one-dimensional, zero-based Array that contains the items that correspond to the keys in keys, or null to sort only keys.
• index - The starting index of the range to sort.
• length - The number of elements in the range to sort.

Returns

Array.Sort<TKey, TValue>(TKey[], TValue[], Int32, Int32) method returns

Example

using System;//from   www .  ja v  a2  s  . c o m
using System.Collections.Generic;

public class ReverseComparer: IComparer<string>
{
    public int Compare(string x, string y)
    {
        // Compare y and x in reverse order. 
        return y.CompareTo(x);
    }
}

public class Example
{
    public static void Main()
    {
        string[] myValues = {"40", "5", "3", "22", "1", "18"  };
        int[] myValuesizes = { 40, 5, 3, 22, 1, 18 };

        Array.Sort(myValues, myValuesizes);

        ReverseComparer rc = new ReverseComparer();
        Array.Sort(myValues, myValuesizes, rc);

        Array.Sort(myValues, myValuesizes, 3, 3);

        Array.Sort(myValues, myValuesizes, 3, 3, rc);

    }
}

The code above generates the following result.
