datatable随机排序

这个是在我的一个小程序中用到的，先帖上来，呵呵

1.                     int tmp;
2.                     int allCount = Phones.dtResult.Rows.Count;
3.                     Random rand = new Random();
4.                     string[] drtmp = new string[3];
5.                     for (int i = 0; i < allCount; i++)
6.                     {
7.                         tmp = rand.Next(0, allCount - 1);
8.                         drtmp[0] = Phones.dtResult.Rows[i][0].ToString();
9.                         drtmp[1] = Phones.dtResult.Rows[i][1].ToString();
10.                         drtmp[2] = Phones.dtResult.Rows[i][2].ToString();
11.                         Phones.dtResult.Rows[i][0] = Phones.dtResult.Rows[tmp][0].ToString();
12.                         Phones.dtResult.Rows[i][1] = Phones.dtResult.Rows[tmp][1].ToString();
13.                         Phones.dtResult.Rows[i][2] = Phones.dtResult.Rows[tmp][2].ToString();
14.                         Phones.dtResult.Rows[tmp][0] = drtmp[0].ToString();
15.                         Phones.dtResult.Rows[tmp][1] = drtmp[1].ToString();
16.                         Phones.dtResult.Rows[tmp][2] = drtmp[2].ToString();
17.                     }
