我开发了一个抽样系统,首先使用实体框架代码法,然后将监查系统作为用户界面。在这里,我使用周转基金服务与用户界面和系统进行沟通。当我使用清单或雇员实体的收藏时,在错误发生后给予。我确信这是因为收集的结果。

" 收到 HTTP 对 http:/ localhost/ GreetingHost/ EmployeeService.svc 的回复时发生错误。 这可能是因为服务端点没有使用 HTTP 协议而具有约束力。 也可能是因为服务器中止了 HTTP 请求上下文( 可能是因为服务关闭) 。 请查看服务器日志了解更多细节 。 "

public class GreetingDBContext :DbContext

    public DbSet<Employee> Employees { get; set; }

    protected override void OnModelCreating(DbModelBuilder modelBuilder)

        return selectedEmployee;

}

我使用 WCF Service 应用程序来托管服务。 这里的代码来自 < strong > GreeetingHost 项目。 iemopleServices. cs.

[ServiceContract]
public interface IEmployeeService
{
    [OperationContract]
    void AddEmployee(string UserId, string Name, int Age);

    [OperationContract]
    Employee getEmployee(string UserId);
}

<强力>雇员服务.svc.cs

public class EmployeeService : IEmployeeService
{
    Greeting.EmployeeService serviceImplementation = new Greeting.EmployeeService();

    public void AddEmployee(string UserId, string Name, int Age)
    {
        serviceImplementation.AddEmployee(UserId,Name,Age);
    }

    public WcfGreating.Employee getEmployee(string UserId)
    {
        return serviceImplementation.getEmployee(UserId);
    }
}

服务主机成功 :

在我的MVC应用程序中,

    EmployeeServiceClient employeeService = new EmployeeServiceClient();

    public ActionResult Profile(string id)
    {
        Employee emp = employeeService.getEmployee(id);

        return View(emp);
    }

当招募雇员服役时,上面提到的通讯例外被退回,有人能帮我吗?

谢谢!
