            if (query != null)
            {
                return query.version;

            }

                return "";
        }
    }

 

linq获取xml数据，id的值是id="1”，正则只取数字，value的值为value="1.1.1”，正则只取数字和点，然后id排序，取第一项

Global.asax.cs在Application_Start调用

 

public void GetVersion()
        {
            VersionInfo.ID = XmlHelper.GetLastVersion();
            VersionInfo.Date = DateTime.Now.ToString("yyyyMMddhhmm");
            VersionInfo.VersionNum = VersionInfo.ID + ":" + VersionInfo.Date;
        }

前台版本调用

<script src="~/Scripts/Effect/znt.min.js?@WisdomFish.Common.VersionInfo.VersionNum"></script>
