发布时间：2020-12-15 23:53:11 所属栏目：百科来源：网络整理

导读：我想在我的LINQ查询中使用UCASE或ToUpper列. var query = from rsn in db.RSLReasons orderby rsn.REFCMNT select new {rsn.REFCODE,rsn.REFCMNT};dtReasons = query.ToADOTable(rec = new object[] { query }); 如果我尝试运行以下代码： var query = from

我想在我的LINQ查询中使用UCASE或ToUpper列.

var query = from rsn in db.RSLReasons
            orderby rsn.REFCMNT
            select new {rsn.REFCODE,rsn.REFCMNT};
dtReasons = query.ToADOTable(rec => new object[] { query });

如果我尝试运行以下代码：

var query = from rsn in db.RSLReasons
            orderby rsn.REFCMNT
            select new {rsn.REFCODE,rsn.REFCMNT.ToString()};
dtReasons = query.ToADOTable(rec => new object[] { query });

我在编译时收到以下错误消息：

Invalid anonymous type member
declarator. Anonymous type members
must be declared with a member
assignment,simple name or member
access.

解决方法

使用ToUpper()…但您需要在匿名类型中指定属性名称,因为无法再推断它.

var query = from rsn in db.RSLReasons
            orderby rsn.REFCMNT
            select new {rsn.REFCODE,REFCMNT = rsn.REFCMNT.ToUpper()};

dtReasons = query.ToADOTable(rec => new object[] { query });
