如何写一个可以序列化的接口 谢谢~

Question

写了个web服务 结果在运行的时候出现 无法序列化接口 ITest请教解决方案 谢谢~

Answer 1

接口的实现类已经支持了序列化 
 我在类前面加了
    [Serializable()]
这个申明了web服务中这么写的    [WebService ( Namespace = "test.test.test.test" )]
    [WebServiceBinding ( ConformsTo = WsiProfiles.BasicProfile1_1 )]
    [ToolboxItem ( false )]
    public class testService : System.Web.Services.WebService
    {        [WebMethod]
        public bool Insert (ITest test,string typeName )
        {
            ITestDAL testDAL = ReflectTestFactory.CreateTestByReflect ( typeName );
            return testDAL.Insert ( test);
        }
    }接口：    public interface ITest 
    {           }实现类：[Serializable()]
    public class T_JT_ZuanTouChengXu:IEntity
    {
        public int id
        {
            get;
            set;
        }
        public Decimal name
        {
            get;
            set;
        }    }

你的ITest 接口里面有没有引用其他不可序列化的对象？

类名前加上[Serializable] 你的类还要符合Serializable的规则,到MSDN上看看吧;
