效果图：
解决方案：主要是绑定后过滤
Code1
1GridView1.DataBind();
2for (int i = 0; i <= GridView1.Rows.Count - 1; i++)
3{
4 DataRowView mydrv = myds.Tables["飞狐工作室"].DefaultView[i];
5 string score = Convert.ToString(mydrv["起薪"]);
6 if (Convert.ToDouble(score) < 34297.00)//大家这里根据具体情况设置可能ToInt32等等
7 {
8 GridView1.Rows[i].Cells[4].BackColor = System.Drawing.Color.Red;
