结合IComparer接口实现对ListBox排序

需求描述:

有个listbox,里面的值是 110 10 70 40 260  
但是设置sort=true的属性后,他的顺序就变为 10 110 260 40 70 
如何做才能让它得到正确的顺序 10 40 70 110 260
这个listbox里的数字都是string型 而且不想让它变为int型 
请问要如何做才对?

========================

 

结合IComparer接口实现排序:

 

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
    }

    private void Form1_Load(object sender, EventArgs e)
    {
        string[] str = new string[] { "110", "10" ,"70" ,"40" ,"260"   };
        object[] data = Sort<string>(str);
        listBox1.Sorted = false;//切记,一定为false
        listBox1.DataSource = data;
    }
    object[] Sort<T>(T[] t)//自定义排序
    {
        double d=0.0;
        ArrayList list = new ArrayList(t);
        //实例化MyCompare
        MyCompare com = new MyCompare();
        list.Sort(com);

        return list.ToArray();
    }
}
class MyCompare : IComparer//自定义MyCompare类
{
    private CaseInsensitiveComparer ObjectCompare;
    public MyCompare()
    {
        ObjectCompare = new CaseInsensitiveComparer();
    }
    public int Compare(object x, object y)//比较大小
    {
        // 比较
        double out1, out2;
        if (double.TryParse(x.ToString(), out out1) && double.TryParse(y.ToString(), out out2))
            return ObjectCompare.Compare(out1, out2);
        else
        {
            // 如果相等返回0
            return 0;
        }
    }
}
