第 21 行位置 4 上的'xs:group'开始标记与 'xr:group' 的结束标记不匹配

Question

我正在处理MVC3项目，当部署到生产中时，我收到了这个错误

The 'xs:group' start tag on line 21 position 4 does not match the end tag of 'xr:group'. Line 30, position 5.

此页面适用于其他域。也尝试添加System.Xml.Linq，但仍然没有成功。提前谢谢。

我有这个执行LINQ的方法GetClientDetails（），看起来错误是由那个LINQ引起的，我使用了EF4。

using (frEntities db = new frEntities())
{
    var client = (from c in db.CLIENTs
                  join p in db.POSITIONs on c.CLIENT_ID equals p.CLIENT_ID
                  join cf in db.Client_Features on c.CLIENT_ID equals cf.Client_ID
                  where p.POSITION_JobCode == jobCode
                  select new{
                      c.CLIENT_ID,
                      p.POSITIONTYPE_ID
                  }).FirstOrDefault();
 }

应答更新

我开始工作了，我们刚刚将EF4更新为EF6.1，并修复了一些参考。

Answer 1

我认为这个错误正是它所说的。

第21行位置4上的"xs:group"开始标记与"xr:group"的结束标记不匹配。第30行，位置5。

在21号线上，你会发现

   <xs:group>

在30号线上你会发现

   </xr:group>

因此，您的XML格式不正确。任何XML解析器都不应该允许这样做而不出错。
