Question

我们正在使用ProtoBuff.NET和我们的WCF服务。 ProtoBehavour已应用于界面，ProtoContract已应用于该类＆amp; ProtoMember已应用于这些属性。

在客户端，我们已将protobuff行为添加到app.config，如下所示，但是当客户端通过WCF服务请求对象时，我们收到错误的线路类型错误。

删除服务上的ProtoBuff行为会导致服务正常工作。

任何人都可以了解正在发生的事情或指出我们正确的方向。

我们正在使用NET TCP绑定。

Answer 1

如果您没有按照marc answer中的建议共享服务合同程序集，那么您需要一种方法让WCF在您的客户端代码中使用ProtoBuf序列化程序而不是WCF默认序列化程序。问题是服务契约中的ProtoBuf属性标记不会位于通常用于在客户端代码中生成服务代理的WSDL文档中。

Answer 2

关于Marc的评论，他说有很多方法可以与SvcUtil或“添加服务参考”VS命令一起进行protobuf-net工作，我找到this帖子，他说：

重新订单= ......，值得查看内容;如果他们提出不同的数字，有办法通过部分类来解决这个问题 - 一个丑陋的黑客，但IIRC有ProtoPartialMember（或类似的）可以应用于类，但谈论个别成员（属性） /领域）。

然后有this帖子，他说：

有两种方法可以解决这个问题;第一个（也是最简单的）是使用WCF在客户端和服务器之间共享合同程序集的能力。如果您可以共享DTO图层，那么事情就会变得简单。

第二种是在客户端添加额外的标记以给它一个线索。您可以通过部分类来完成此操作，例如在单独的代码文件中（不要编辑生成的文件）：

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

更明确的替代方案是：

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