WCF通用类

Question

它如何作为WCF服务工作？

public class BusinessObject<T> where T : IEntity
{
    public T Entity { get; set; }

    public BusinessObject(T entity)
    {
        this.Entity = entity;
    }
}

public interface IEntity { }

public class Student : IEntity
{
    public int StudentID { get; set; }
    public string Name { get; set; }
}

我想公开BusinessObject <T>类以及在WCF服务中继承IEntity接口的所有类.

我的代码在C#,.NET Framework 4.0中,在Visual Studio 2010 Pro中构建.

在通过WCF将BusinessObject暴露给客户端时,必须使用封闭的泛型类型.

[DataContract]
public class BusinessObject<T> where T : IEntity
{
    [DataMember]
    public T Entity { get; set; }

    public BusinessObject(T entity)
    {
        this.Entity = entity;
    }
}  

[ServiceContract]
interface IMyContract {
[OperationContract]
BusinessObject<Student> GetStudent(...) // must be closed generic
}
