}生成的客户端调用代码，并未将student类封装进去，求解，怎样将student封装进去，供客户端调用？

Answer 2

去掉你所有的attribute就可以了。看题目，我还真纳闷，除了用手写，还有人用脚写么？

Answer 3

去掉就好了？去掉就错的离谱了。
这题目是可以吐槽下。因为你的方法中没有明确使用到student类，所以就没有封装进去（没试，我猜的，但的确有这种可能。）
所谓没有明确使用到，就是你没用通过参数或者返回值去使用，而是函数内部使用，接口声明是体现不出来，那么系统根据接口的定义是不知道是否需要那个student类，此时你只要添加一个属性就OK。例如：
[ServiceKnownType(typeof(student))]
[OperationContract]
  object object1();

Answer 4

er...
我的项目中就直接没任何attribute直接用的。咋没问题。

Answer 5

估计你的项目是直接引用的Dll文件，创建一个公共DLL，同时客户端和服务端引用，效率最高，我就是这样做的，但如果要让VS去识别服务端的接口信息，你不加属性它就认不到了。
