数组的Sort方法的用法

[yuqi508]

现有结构体
Public Structure FriendItem
Public UserID As String
Public NickName As String
Public Email As String
Public UserFace As String
Public Status As Integer
End Structure
定义结构体数组Dim Friends() as FriendItem
并已付值
现在要用数组的Sort方法按Status 排序数组
请问怎么实现

需要重载Sort()方法
找找资料~

参考
using System;

namespace DotManagement.EntryManagement
{
public class FileItem :IComparable
{
private string fileName;

public FileItem(string fileName)
{
this.fileName = fileName;
}
public string FileName
{
get {return this.fileName;}
}


public int CompareTo(object obj)
{

//if (obj == null)
// return 1;

string compareFileName = ((FileItem)obj).FileName;

//if (this.FileName == compareFileName)
// return 0;
//if (this.FileName < compareFileName)
// return -1;
//if (this.FileName > compareFileName)
// return 1;
//return 0;
return this.FileName.CompareTo(compareFileName);
}
}
}
使用
ArrayList al = new ArrayList();
foreach(string fileName in Directory.GetFiles("c;\\"))
{
al.Add(new FileItem(fileName));
}
al.Sort();

msdn 里面查找Array.Sort或者ArrayList.Sort
