EntitySqlException在Entity Framework中选择代码第一个dbcontext [英] EntitySqlException on select with code first dbcontext in Entity Framework

问题描述

var codeFirstRepositor = new Donors();
var list = codeFirstRepositor.CampaignReps.Select(c => c).ToList();

• 当我将一个断点放在 CampaignRep 类构造函数根本没有被调用 - 异常似乎发生在对象实例化之前


• When I put a breakpoint inside the CampaignRep class constructor it is not called at all - the exception seems to occur before object instantiation

public class Donors : DbContext
{
    public Donors()
    {
        // Needed for WCF serialization to work
        Configuration.ProxyCreationEnabled = false;
    }
    public DbSet<CampaignRep> CampaignReps { get; set; }
}





EntitySqlException





'CampaignsReps'不是Transient.collection [MyNameSpace.Donor（Nullable = True，DefaultValue =）]]的成员。要提取集合元素的属性，请使用子查询遍历集合。接近转义的标识符，第1行第10列。

这个错误的原因是什么？ >


What is the cause of this error?

推荐答案

删除Select（c => c），然后重试。另外你为什么甚至在你的查询？

Remove the Select(c => c) and try again. Also, why do you even have that in your query?
