麻烦各位帮看下这段合并相同列代码有什么问题吗？总是提示; expected

private void  SpanGrid()
  {
   int i;
   int j;
   int intspan;
   string temp;
     string temp3;
    for(i=0;i<mydatagrid1.Items.Count;i++)
    {
     DataGridItem _item = mydatagrid1.Items[i];
     intspan = 1;
j=j+1;
     temp =mydatagrid1.Items[i].Cells[1].Text;
     temp3=mydatagrid1.Items[j].Cells[1].Text;
     string temp2= temp;
        if (temp2.Equals(temp3))
      {
       intspan++;
       mydatagrid1.Items[i].Cells[1].RowSpan = intspan;
       mydatagrid1.Items[j].Cells[1].Visible = false;
      }
      else
      {
       break;
      }

  }
} --------------------编程问答-------------------- 你这是ASP.NET吧，没有问题。另外把你j拿到外面



 private int j;

        private void SpanGrid()

        {

            int i;

            

            int intspan;

            string temp;

            string temp3;

            for (i = 0; i < mydatagrid1.Items.Count; i++)

            {

                DataGridItem _item = mydatagrid1.Items[i];

                intspan = 1;

                j += 1;

                temp = mydatagrid1.Items[i].Cells[1].Text;

                temp3 = mydatagrid1.Items[j].Cells[1].Text;

                string temp2 = temp;

                if (temp2.Equals(temp3))

                {

                    intspan++;

                    mydatagrid1.Items[i].Cells[1].RowSpan = intspan;

                    mydatagrid1.Items[j].Cells[1].Visible = false;

                }

                else

                {

                    break;

                }



            }

        }

补充：.NET技术 ,  C#
