 1/// <summary>
 2 /// 合并GridView中某列相同信息的行（单元格） 
 3 /// </summary>
 4 /// <param name="GridView1">GridView</param>
 5 /// <param name="cellNum">第几列</param>
 6 public static void GroupRows(GridView GridView1, int cellNum)
 7 {
 8     int i = 0, rowSpanNum = 1;
 9     while (i < GridView1.Rows.Count - 1)
10     {
11         GridViewRow gvr = GridView1.Rows[i];
12 
13         for (++i; i < GridView1.Rows.Count; i++)
14         {
15             GridViewRow gvrNext = GridView1.Rows[i];
16             if (gvr.Cells[cellNum].Text == gvrNext.Cells[cellNum].Text)
17             {
18                 gvrNext.Cells[cellNum].Visible = false;
19                 rowSpanNum++;
20             }
21             else
22             {
23                 gvr.Cells[cellNum].RowSpan = rowSpanNum;
24                 rowSpanNum = 1;
25                 break;
26             }
27 
28             if (i == GridView1.Rows.Count - 1)
29             {
30                 gvr.Cells[cellNum].RowSpan = rowSpanNum;

我自己改好了,   不过用不不是你的方法
 public static void MergeRows(GridView gridView, int cellNum)
        {
            for (int rowIndex = gridView.Rows.Count - 2; rowIndex >= 0; rowIndex--)
            {
                GridViewRow row = gridView.Rows[rowIndex];
                GridViewRow previousRow = gridView.Rows[rowIndex + 1];
                for (int i = 0; i < row.Cells.Count; i++)
                {                    if (row.Cells[i].Text + row.Cells[cellNum].Text == previousRow.Cells[i].Text + previousRow.Cells[cellNum].Text)
                    {
                    row.Cells[i].RowSpan = previousRow.Cells[i].RowSpan < 2 ? 2 :
                                           previousRow.Cells[i].RowSpan + 1;
                    previousRow.Cells[i].Visible = false;
                    }
                }
            }
        }
就是添加个变量就OK了  呵呵  不过也谢谢你,结贴分不能给自己 算你捡便宜了
