             string art_code = string.Format("G{0}", DateTime.Now.ToString("yyyyMMddhhmmss"));             Gallery.BoothReservation BR = new BoothReservation(); 
             ArtInfo ai = new ArtInfo();
             ai.Art_name = art_name;
             ai.Art_description = art_descript;
             ai.Art_type = art_type;
             ai.Art_size = art_size;
             ai.Art_material = art_material;
             ai.Art_authorName = art_author;
             ai.Art_createDate = art_date;
             ai.Art_imgUrl = Path.GetFileName(art_pic);
             ai.Art_Code = art_code;
             bool isOK = BR.InsertArt(ai, 0);
             if (isOK)
             {
                 Lterror.Text = webUtility.alert("添加国画成功");
             }内容加到数据库了 但是就是不弹出框提示

public static string alert(string strText)
    {
        return "<script>alert('" + strText + "')</script>";
    }
只是alert方法
