我正在开发一个使用实体框架代码优先方法和MVC作为用户界面的样本系统。在这里，我使用WCF服务与用户界面和系统进行通信。当我在我的Employee实体中使用一个List或一个集合时，会出现以下错误。我相信这是由于收集。 “使用IList或ICollection作为DataMember时的WCF服务错误
”接收到http：/localhost/GreetingHost/EmployeeService.svc的HTTP响应时发生错误，这可能是由于服务端点绑定不使用HTTP协议造成的，也可能是由于HTTP请求上下文由服务器（可能由于服务关闭）中止，请参阅服务器日志详细信息“
这里是我的实体和服务，其中包括在问候项目：。
Employee.cs
[DataContract]
[KnownType(typeof(Greeting))]
public class Employee
{
[Key()]
[DataMember]
public string UserId { get; set; }
[DataMember]
public string Name { get; set; }
[DataMember]
public int Age { get; set; }
[DataMember]
[ForeignKey("EmployeeUserID")]
public virtual IList<Greeting> Greetings
{
get
{
if (this._greetings == null)
{
this._greetings = new List<Greeting>();
}
return _greetings;
}
set { _greetings = value; }
}
private IList<Greeting> _greetings;
}
Greeting.cs
[DataContract]
public class Greeting
{
[Key()]
[DataMember]
public int GreetingID { get; set; }
[DataMember]
public string Salutation { get; set; }
[DataMember]
public string Message { get; set; }
[DataMember]
public DayStatusWrapper DayStatusWrapper { get; set; }
[DataMember]
public string EmployeeUserID { get; set; }
[DataMember]
public virtual Employee Employee { get; set; }
}
GreetingDBContext.cs
public class GreetingDBContext :DbContext
{
public DbSet<Greeting> Greetings { get; set; }
public DbSet<Employee> Employees { get; set; }
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
modelBuilder.Conventions.Remove<IncludeMetadataConvention>();
base.OnModelCreating(modelBuilder);
modelBuilder.Entity<Employee>().
HasMany(d => d.Greetings).
WithRequired(c => c.Employee).
HasForeignKey(c => c.EmployeeUserID).WillCascadeOnDelete();
modelBuilder.Entity<Employee>()
.HasKey(c => c.UserId);
modelBuilder.Entity<Greeting>()
.HasKey(c => c.GreetingID);
}
}
EmployeeServices.cs
public class EmployeeService
{
private GreetingDBContext db = new GreetingDBContext();
public void AddEmployee(string UserId, string Name, int Age)
{
Employee emp = new Employee();
emp.UserId = UserId;
emp.Name = Name;
emp.Age = Age;
db.Employees.Add(emp);
db.SaveChanges();
}
public Employee getEmployee(string UserId)
{
Employee selectedEmployee = null;
foreach (Employee item in db.Employees)
{
if (item.UserId == UserId)
{
selectedEmployee = item;
break;
}
}
return selectedEmployee;
}
}
我使用WCF服务应用程序托管服务秒。下面的代码是从GreetingHost project.IEmployeeServices.cs
[ServiceContract]
public interface IEmployeeService
{
[OperationContract]
void AddEmployee(string UserId, string Name, int Age);
[OperationContract]
Employee getEmployee(string UserId);
}
EmployeeService.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应用服务上面使用的参考：
EmployeeServiceClient employeeService = new EmployeeServiceClient();
public ActionResult Profile(string id)
{
Employee emp = employeeService.getEmployee(id);
return View(emp);
}
从服务中收集员工时，返回上述CommunicationException。谁能帮我？
谢谢！

列表大小是多少？检查服务是否正常工作，当列表包含单个项目，如果是，那么你必须增加一些设置值在配置 – VJAI
谢谢马克，它有5个项目，我尝试过单个项目，但仍然没有成功.same错误返回。您是否需要查看配置文件？ – iJay
是的，请发布客户端和服务器配置 – VJAI
