写WebMethod方法再调用

#region 删除文件(图片)
        [WebMethod]
        public string FileDelete(string fileName)
        {
            try
            {
                File.Delete(System.Web.Hosting.HostingEnvironment.ApplicationPhysicalPath + "/ClientBin/" + fileName);
                return "ok";
            }
            catch (Exception e)
            {
                return e.ToString();
            }
        }
        #endregion
