本文介绍了ProtoBuff.NET WCF - 客户端上的线类型错误不正确的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我们在 WCF 服务中使用 ProtoBuff.NET.ProtoBehavour 已应用于接口，ProtoContract 已应用于类 &ProtoMember 已应用于属性.

在客户端，我们已将 protobuff 行为添加到 app.config 中，如下所示，但是当客户端通过 WCF 服务请求对象时，我们会收到不正确的线路类型错误.

删除服务上的 ProtoBuff 行为会导致服务正常运行.

任何人都可以对正在发生的事情有所了解或为我们指明正确的方向.

我们使用的是 NET TCP 绑定.

客户端配置

解决方案

关于 Marc 的评论，他指出有一些方法可以使 protobuf-net 与 SvcUtil 或添加服务引用"一起工作；VS 命令，我发现 this发帖，他说:

<块引用>

Re Order=...，内容值得一看；如果他们想出不同的数字，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，但它谈论的是单个成员(属性/字段).

然后是这个 发帖，他说:

<块引用>

有两个选项可以解决这个问题；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约程序集的能力.如果您可以共享 DTO 层，那将使事情变得简单.

第二种是在客户端添加额外的标记以提供线索.您可以通过分部类执行此操作，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)]/* 转移所有 DataMember 订单 */公共部分类 tbEmployee {}}

<块引用>

更明确的替代方法是:

namespace YourNamespace {[ProtoPartialMember(1, EmployeeID")][ProtoPartialMember(2, "EmployeeName")]公共部分类 tbEmployee {}}

We are using ProtoBuff.NET with our WCF service. ProtoBehavour has been applied to the interface, ProtoContract has been applied to the class & ProtoMember has been applied to the properties.

On the client side we have added the protobuff behavior to the app.config as below however when the client requests a object via the WCF service we receive a incorrect wire type error.

Removing the ProtoBuff behavior on the service results in the service working fine.

Can anybody please shed some light on what is happening or point us in the right direction.

We are using the NET TCP binding.

解决方案

In regard to Marc's comment where he stated that there were ways to make protobuf-net work along with SvcUtil or "Add Service Reference" VS command, I found this post, where he says:

Re Order=..., it would be worth checking the contents; if they are coming up with different numbers, there are ways to fix this via a partial class - an ugly hack, but IIRC there is ProtoPartialMember (or similar) that can be applied to the class, but which talks about an individual member (property/field).

Then there is this post, where he says:

There are 2 options for fixing this; the first (and easiest) is to use WCF's ability to share a contract assembly between client and server. If you can share the DTO layer, that'll keep things simple.

The second is to add additional markers at the client to give it a clue. You can do this via a partial class, for example in a separate code file (don't edit the generated file):

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

a more explicit alternative is:

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