.net遠程傳遞實體框架時生成的對象

Question

我有一個與.net遠程處理問題（是的，這是我第一次嘗試使用它，所以我很抱歉，如果這是一個簡單的解決方案一個愚蠢的問題）我一直在尋找兩天，並且找不到解決我的問題的方法，所以如果我在某處錯過了答案，我會提前道歉。

我使用這個代碼構建的服務器/客戶端系統：

服務器：

public Server() { 
    DbConnector db = new DbConnector(); 

    BinaryServerFormatterSinkProvider provider = new BinaryServerFormatterSinkProvider(); 
    provider.TypeFilterLevel = TypeFilterLevel.Full; 
    IDictionary props = new Hashtable(); 
    props["port"] = DbConnector.PORT; 
    TcpChannel channel = new TcpChannel(props, null, provider); 

    ChannelServices.RegisterChannel(channel, true); 
    RemotingConfiguration.RegisterWellKnownServiceType(
     typeof(DbConnector), "test", 
     WellKnownObjectMode.SingleCall); 
} 

客戶：

public Form1() { 
    InitializeComponent(); 

    BinaryServerFormatterSinkProvider provider = new BinaryServerFormatterSinkProvider(); 
    provider.TypeFilterLevel = TypeFilterLevel.Full; 
    IDictionary props = new Hashtable(); 
    props["port"] = 0; 
    props["ip"] = DbConnector.IP; 
    TcpChannel channel = new TcpChannel(props, null, provider); 

    ChannelServices.RegisterChannel(channel, true); 
    db = (DbConnector)Activator.GetObject(typeof(DbConnector), "tcp://188.x.x.x/test"); 
    InitRest(); 
} 

每當我（可以使用本地主機，但也儘量在本地與廣域網IP）一切正常，但只要我在單獨的機器上嘗試它，客戶端會引發異常。

我打印出來的文字來時的DbConnector調用構造函數，我可以看到客戶端與服務器聯繫，但我被困在那。

經過多次測試後，似乎問題不在於連接本身，而是當我調用從生成代碼的系統的實體框架部分返回對象的函數時。我已經修改與[Serializable接口]和類：MarshalByRefObject的，如下所示：

//------------------------------------------------------------------------------ 
// <auto-generated> 
// This code was generated from a template. 
// 
// Manual changes to this file may cause unexpected behavior in your application. 
// Manual changes to this file will be overwritten if the code is regenerated. 
// </auto-generated> 
//------------------------------------------------------------------------------ 

namespace Database 
{ 
    using System; 
    using System.Collections.Generic; 

    [Serializable] 
    public partial class customer: MarshalByRefObject 
    { 
     public customer() 
     { 
      this.car = new HashSet<car>(); 
     } 

     public int customerId { get; set; } 
     public string name { get; set; } 

     public virtual ICollection<car> car { get; set; } 
    } 
} 

然而，當客戶端程序調用返回一個「客戶」對象，並試圖訪問它的客戶端函數拋出上述異常。

我的猜測是，因爲這個類是從MarshalByRefObject派生出來的，所以它是回調部分。

我試圖爲客戶端通道使用特定的端口，但無濟於事。

我希望有人有這個解決方案，最終可能只是我缺少關鍵部分。

Answer 1

我沒有通過使包裝類對象解決它，並利用它來進行的傳輸代替。多一點工作，但它的工作。顯然你不應該能夠通過這些渠道發送實體框架生成的對象。

Answer 2

我想我找到了它，這要感謝您提供您的樣品！

ChannelServices.RegisterChannel(channel, true); 

設置ensureSecurity假

ChannelServices.RegisterChannel(channel, false);
