本文实例讲述了C#中Arraylist的sort函数用法。分享给大家供大家参考。具体如下：

ArrayList的sort函数有几种比较常用的重载：

1.不带参数

2.带一个参数

public virtual void Sort( IComparer comparer)

参数

comparer

类型：System.Collections.IComparer

比较元素时要使用的 IComparer 实现。

- 或 -

null 引用（Visual Basic 中为 Nothing）将使用每个元数的 IComparable 实现。

示例:

using System;using System.Collections;public class SamplesArrayList { public class myReverserClass : IComparer { // Calls CaseInsensitiveComparer.Compare with the parameters reversed. int IComparer.Compare( Object x, Object y ) { return( (new CaseInsensitiveComparer()).Compare( y, x ) ); } } public static void Main() { // Creates and initializes a new ArrayList. ArrayList myAL = new ArrayList(); myAL.Add( "The" ); myAL.Add( "quick" ); myAL.Add( "brown" ); myAL.Add( "fox" ); myAL.Add( "jumps" ); myAL.Add( "over" ); myAL.Add( "the" ); myAL.Add( "lazy" ); myAL.Add( "dog" ); // Displays the values of the ArrayList. Console.WriteLine( "The ArrayList initially contains the following values:" ); PrintIndexAndValues( myAL ); // Sorts the values of the ArrayList using the default comparer. myAL.Sort(); Console.WriteLine( "After sorting with the default comparer:" ); PrintIndexAndValues( myAL ); // Sorts the values of the ArrayList using the reverse case-insensitive comparer. IComparer myComparer = new myReverserClass(); myAL.Sort( myComparer ); Console.WriteLine( "After sorting with the reverse case-insensitive comparer:" ); PrintIndexAndValues( myAL ); } public static void PrintIndexAndValues( IEnumerable myList ) { int i = 0; foreach ( Object obj in myList ) Console.WriteLine( "\t[{0}]:\t{1}", i++, obj ); Console.WriteLine(); }}

希望本文所述对大家的C#程序设计有所帮助。
