c# - asp.net gridview 如果单元格行值相等则

Question

我正在填充数据表，然后将其绑定(bind)到 GridView 。现在我正在读取网格中的行并为行着色 if value = [x]。

当我尝试在页面上显示彩色行时，我得到了复制。假设我已经为 1 行着色，但 response.write 将是相同结果的 100 倍。下面是我的代码，希望有人能帮忙:

protected void gv1_RowDataBound(object sender, GridViewRowEventArgs e)
{
    string alert = Request.QueryString["check"];

    // loop over all the Rows in the Datagridview 
    foreach (GridViewRow row in gv1.Rows)
    {
        // if condition is met color the row text 

        if (gv1.Rows[0].Cells[0].Text.ToString() == alert)
        {
            Session ["fn"] = gv1.Rows[0].Cells[2].Text;
            gv1.Rows[0].ForeColor = Color.Red;
    }
        Response.Write(Session["fn"]);
}

protected void gv1_RowDataBound(object sender, GridViewRowEventArgs e)
{
    string alert = Request.QueryString["check"];

        if (e.Row.Cells[0].Text.ToString() == alert)
        {
            Session ["fn"] = e.Rows.Cells[2].Text;
            e.Rows.ForeColor = Color.Red;

        Response.Write(Session["fn"]);
        }
}
