ProtoBuff.NET WCF - 客戶端上的線路類型錯誤

Question

我們在我們的WCF服務中使用ProtoBuff.NET。 ProtoBehavour已經應用到界面上，ProtoContract已經應用到類& ProtoMember已經應用到了屬性中。

在客戶端，我們已經將protobuff行爲添加到了app.config中，但是，當客戶端通過WCF服務請求對象時，我們會收到錯誤的導線類型錯誤。

在服務上刪除ProtoBuff行爲會導致服務正常工作。

任何人都可以請點亮發生了什麼事情，或指出我們朝着正確的方向。

我們正在使用NET TCP綁定。

Answer 1

如果您沒有按照marc的answer中的建議共享服務協議程序集，那麼您需要一種方法使WCF在客戶端代碼中使用ProtoBuf序列化程序，而不是WCF默認序列化程序。問題是服務合約中的ProtoBuf屬性標記不會位於通常用於在客戶端代碼中生成服務代理的WSDL文檔中。

關於馬克的評論，他指出，有辦法讓protobuf網工作，SvcUtil工具沿着或「添加服務引用」 VS命令，我發現this後，他說：

回覆Order = ...，這將是值得檢查的內容;如果他們想出不同的數字，有辦法通過一個部分課程來解決這個問題 - 一個醜陋的黑客，但IIRC有ProtoPartialMember（或類似的），可以應用於課堂，但談論一個單獨的成員（財產/領域）。

再有就是this後，他說：

有2個選項用於固定這一點;第一個（也是最簡單的）是使用WCF在客戶端和服務器之間共享合同組件的能力。如果你可以分享DTO層，這將使事情變得簡單。

第二個是在客戶端添加額外的標記以給它一個線索。可以通過一個局部類做到這一點，例如在一個單獨的代碼文件（不要編輯所生成的文件）：

namespace YourNamespace { 
    [ProtoContract(DataMemberOffset = 1)] /* shift all DataMember orders */ 
    public partial class tbEmployee {} 
} 

更加明確的選擇是：

namespace YourNamespace { 
    [ProtoPartialMember(1, "EmployeeID")] 
    [ProtoPartialMember(2, "EmployeeName")] 
    public partial class tbEmployee {} 
}
