实施.Net Remoting项目时出错 [英] Error in implement .Net Remoting project

问题描述

大家好，
我正在实施.Net Remoting Project，但出现了一些问题，请帮帮我.
我将代理对象编码为客户端和服务器之间的通讯方式为:

Hi all,
I''m implementing .Net Remoting Project but it occurs some problem, pls help me.
I code proxy object to comunicate between client and server as:

public class clsComponent : MarshalByRefObject
    {
        public DataSet TransDetails(string strServer)
        {
            string strConnectString = "server = " + strServer + "; database = ImperialBank; UID=phuc;PWD=phuc";
            SqlConnection sqlCon;
            SqlDataAdapter sqlDataApt;
            string strQuery = "Select Transaction_Id as 'Transaction Id', Transaction_Date as 'Transaction Date', " +
                               "Credit, Debit, Bal_Amt as 'Balance Amount' from Transactions";
            sqlCon = new SqlConnection(strConnectString);
            sqlDataApt = new SqlDataAdapter(strQuery, sqlCon);
            DataSet ds = new DataSet();
            sqlDataApt.Fill(ds, "Transactions");
            return ds;
        }
        public IQueryable<CustomerDetail> fnGetAllEmp()
        {
            var c = from c1 in db.CustomerDetails
                    select c1;
            return c;
        }
}

客户端已连接到服务器，客户端调用 TransDetails() =>好的.但是客户端调用 fnGetAllEmp()，则会发生错误:
在程序集"System.Data"中，

Client was connected to server and client call TransDetails() => ok. But client call fnGetAllEmp(), it occur error:

Type 'System.Data.Linq.DataQuery`1[[ComponentApp.CustomerDetail, ComponentApp, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null]]' in Assembly 'System.Data.Linq, Version=3.5.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' is not marked as serializable.

对不起，我的语言！

Sorry my language!

推荐答案

就像错误提示System.Data.Linq.DataQuery对象必须具有Serializable属性一样，因为它是系统类，所以您不能做任何事情(BinaryFormatter序列化程序都需要这样做).

不要像这样编组对象，请使用Dataset.

Like the error says the System.Data.Linq.DataQuery object must have a Serializable attribute, since it is a system class then you can''t do anything about it (BinaryFormatter serializer requires this).

Don''t Marshal your objects like this, use the Dataset for this.

亲爱的，
我删除了 MarshalByRefObject ，它没有错误，尽管我使用LINQ运行方法.鲍比请给我清楚地解释一下！

Dear,
I removed MarshalByRefObject, it have no error although i run method using LINQ. Some boby please explain to me clearly!
