实体类型'员工'没有定义键。定义此实体类型的键。员工：entitytype：entityset'employee'基于没有定义键的类型'employee'。 [英] Entitytype 'employee' has no key defined. Define the key for this entitytype. Employees: entitytype: entityset 'employees' is based on type 'employee' that has no keys defined.

问题描述

在模型生成期间检测到一个或多个验证错误：



mvcstarted.Models.employee :: EntityType'employee'没有定义键。定义此EntityType的密钥。

employees：EntityType：EntitySet; employees;基于类型;员工;没有定义键。





public ActionResult Details（int id）

{

employeecontext empt = new employeecontext（）;

employee emptt = empt.employees.Single（emp => emp.Emp_id == id）;



返回查看（emptt）;

}



我尝试过：



i到目前为止已经尝试了这么多时间，但问题仍然如上所述请告诉我我还能做些什么

One or more validation errors were detected during model generation:

mvcstarted.Models.employee: : EntityType 'employee' has no key defined. Define the key for this EntityType.
employees: EntityType: EntitySet;employees; is based on type;employee; that has no keys defined.


public ActionResult Details(int id)
{
employeecontext empt = new employeecontext();
employee emptt = empt.employees.Single(emp => emp.Emp_id== id);

return View(emptt);
}

What I have tried:

i have tried so much time until now but issue still arrising as above please suggest me what can i do further

推荐答案

查看我的博客 - EntityType：EntitySet'[Entity Name]'基于没有键定义的类型'[Entity Name]' Tadit Dash [ ^ ]

Check out my blog - EntityType: EntitySet ‘[Entity Name]’ is based on type ‘[Entity Name]’ that has no keys defined | Tadit Dash[^]

你需要做两件事（这与代码有关）第一种方法）：



1-确定主键

You need to do two things(this is related to code first approach):

1- Determine the primary key

[Key]
public int BidYearID { get; set; }

2-你必须构建你的解决方案然后尝试添加视图

2- you have to build your solution then try to add the view
