[bold]编译器错误信息: [/bold]CS0117: “System.Web.UI.WebControls.GridView”并不包含“Cells”的定义

for (int i = 0; i <= GridView1.Rows.Count - 1; i++)
        {
            CheckBox cbox = (CheckBox)GridView1.Rows[i].FindControl("CheckBox1");
            if (cbox.Checked == true)
            {
           }

CheckBox chk = (CheckBox)gr.Rows[i].Cells[5].FindControl("chk");
