如果单元格行值相等，则 asp.net 网格视图

我正在填充一个数据表，然后将其绑定到网格视图。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，它会重复。假设我已经为 1 行着色，但response.write的结果将是相同的 100 倍。以下是我的代码，希望有人可以提供帮助：

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"]);
        }
}
