效果图：

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