我遇到了一些我的代码.我有一个控制器,我打电话从我的数据库中检索公司列表.但是,当我测试它时,我得到一个错误,指出状态:LINQ to Entities无法识别方法System.String ToString()方法,并且此方法无法转换为存储表达式.

我似乎无法找到解决这个问题的方法,并且有人建议我使用foreach循环.

public List<SelectListItem> GetCompanyList()
{
    using (var ctx = new Risc_Track_beEntities())
    {
        var companies = ctx.tblCodeBrokerComps.Where(comp => comp.BrokerCompStatus == 1);
        var activeBrokerLocs = companies.Select(b => new SelectListItem
        {
            Value = b.BrokerCompID.ToString(),
            Text = b.BrokerComp
        });
        return activeBrokerLocs.ToList<SelectListItem>();
    }
}

这个问题与上一期有关.我收到一个无效的匿名类型成员错误.然而,我已经完成了修复并确保它与我试图提取的给定数据相匹配.

var branches = ctx.tblCodeBrokBranches.Where(comp => comp.BrokOffID == 1);
                var activeBrokerLocs = branches.Select(b => new
                {
                    b.BrokOffID.ToString(), //Invalid anonymous type member declarator. Anonymous type members must be declared with a member assignment, simple name or member access.
                    b.BrokBranch
                })
                                .AsEnumerable()
                                .Select(b => new SelectListItem
                                {
                                    Value = b.BrokOffID.ToString(),
                                    Text = b.BrokBranch
                                });
