Entity framework 我可以修改它以更好的方式修复此错误吗

这是我的密码

  using (var conn = new DataEntities())
            {
                var query = from c in conn.servers where c.Servername != null select c;
                servers srv = query.FirstOrDefault();
                if (srv != null)
                {
                    Start.IPAddress = srv.ServerIP;
                    Start.ServerName = srv.Servername;
                    Start.GamePort = Convert.ToUInt16(srv.ServerPort);
                }
                Start.Servers.Add(Start.ServerName, Start.GamePort);
            }

服务器srv=query.FirstOrDefault（）；//这里出错

未经处理的异常

type 'System.Data.Entity.Core.EntityCommandExecutionException' occurred in EntityFramework.dll

Additional information: An error occurred while executing the command definition. See the inner exception for details.

能以通常更好的方式写信吗

一些建议我还是初学者^^ 谢谢

解决了

using (var conn = new DataEntities())
            {
                var query = from c in conn.servers
                            select new
                            {
                                c.Servername,
                                c.ServerPort,
                                c.ServerIP
                            };
                foreach (var item in query)
                {
                    Start.IPAddress = item.ServerIP;
                    Start.ServerName = item.Servername;
                    Start.GamePort = Convert.ToUInt16(item.ServerPort);
                }
                Start.Servers.Add(Start.ServerName, Start.GamePort);
            }

什么是内部异常（

请参阅内部异常以了解详细信息。

）？这里是{“每个派生表都必须有自己的别名”}看起来您正在将EF与MySQL一起使用，MySQL正在引发该异常。感谢您的回复，这是我的查询错误，我解决了它谢谢
