获得一个DataTable中的奇数行和偶数行

DataTable dt = GetData();

int count = dt.Rows.Count;

DataTable dt_jishu = new DataTable();

DataTable dt_oushu = new DataTable();

dt_jishu = dt.Copy();

dt_oushu = dt.Copy();

for(int i = 1; i <= count/2; i++)

dt_jishu.Rows.RemoveAt(i);

for(int i= 0 ;i <= count/2-1; i++)

dt_oushu.Rows.RemoveAt(i);

如果有datalist，需要显示这样的格式：

1 a | 2 b

3 c | 4 d

6 e | 6 f

7 g | 8 h

this.dl1.DataSource = dt_jishu;

this.dl1.DataBind();

this.dl2.DataSource = d;

this.dl2.DataBind();

使用下面的语句分别作为 dl1、dl2的排序编号：

<%#((System.Web.UI.WebControls.DataListItem)Container).ItemIndex*2+1%>

<%#((System.Web.UI.WebControls.DataListItem)Container).ItemIndex*2+2%>
