使用复选框检索ASP中数据网格中的多个数据项.NET C#

     protected void Button1_Click(object sender, EventArgs e)
  {
   foreach (DataGridItem di in GridView1.Items)
   {
       HtmlInputCheckBox chkBx = (HtmlInputCheckBox)di.FindControl("CheckBox1");
       if (chkBx != null && chkBx.Checked)
       {
          //What should I write to get the Items of that checked row.
       }
     }
   }

帮助我如何检索每个选中行的行项目。

我试过这样做，但它没有在标签上添加任何内容

      foreach (GridViewRow di in GridView1.Rows)
   {
       HtmlInputCheckBox chkBx = (HtmlInputCheckBox)di.FindControl("CheckBox1");
       if ( chkBx != null && chkBx.Checked)
       {
           FID[j] += di.Cells[2].Text;
           j++;
           Label1.Text += di.Cells[2].Text;
            }
       }
