asp.net - 反序列化操作的请求消息正文时出现WCF错误

我有一个asp.net客户端Web应用程序和一个从架构xsd开发的WCF Web服务。调用服务时，在反序列化请求正文时出现错误。我尝试更新服务参考，但没有帮助。

这是我的代码:

OSEOP.HMA_OrderingBindingClient client = new OSEOP.HMA_OrderingBindingClient();

OSEOP.GetCapabilitiesRequest request = new OSEOP.GetCapabilitiesRequest();
request.GetCapabilities = new OSEOP.GetCapabilities();
request.GetCapabilities.service = "OS";

string[] arrAcceptedVersions = { "1.0.0", "2.0.0" };
request.GetCapabilities.AcceptVersions = arrAcceptedVersions;

OSEOP.Capabilities capabilities = client.GetCapabilities(request.GetCapabilities);


txtGetCapabilitiesResponse.Text = capabilities.Contents.ToString();

client.Close();

这是错误:

  InnerException:

如您所见，该错误发生在客户端，并且永远不会发送到WCF服务。因此，我的MessageLogging中没有任何内容。这就是为什么我认为它与服务参考有关。

有人可以帮忙吗？

编辑＃1:
我不明白的是，GetCapabilities带有一个GetCapabilitiesRequest参数，但是当我实现客户端时，我的智商要求一个OSEOP.GetCapabilities对象。

OSEOP是我命名的Web参考。

public class OrderingService : HMA_OrderingBinding
{
    public GetCapabilitiesResponse GetCapabilities(GetCapabilitiesRequest request)
    {
        throw new NotImplementedException();
    }

    GetCapabilitiesResponse GetCapabilities(GetCapabilitiesRequest request);

    public GetCapabilitiesRequest(GetCapabilities GetCapabilities)

}

编辑＃2 @Marc:
马克，您的回答很有帮助。但是您会看到服务器端是这样的:

GetCapabilitiesResponse GetCapabilities(GetCapabilitiesRequest request)

但是我的智慧认为这是这样的:

Capabilities GetCapabilities(GetCapabilities GetCapabilities1)

我已经在IOrder.cs文件中找到了一段代码(从架构生成的47,256行代码)，我确定是引起问题的原因，但是我尝试注释掉故障功能，更新服务引用以及我的intellisense 仍然想要GetCapabilities GetCapabilities1

[System.Diagnostics.DebuggerStepThroughAttribute()]
[System.CodeDom.Compiler.GeneratedCodeAttribute("System.ServiceModel", "3.0.0.0")]
public partial class HMA_OrderingBindingClient : System.ServiceModel.ClientBase<HMA_OrderingBinding>, HMA_OrderingBinding
{

    public HMA_OrderingBindingClient()
    {
    }

    [System.ComponentModel.EditorBrowsableAttribute(System.ComponentModel.EditorBrowsableState.Advanced)]
    GetCapabilitiesResponse HMA_OrderingBinding.GetCapabilities(GetCapabilitiesRequest request)
    {
        return base.Channel.GetCapabilities(request);
    }

    public Capabilities GetCapabilities(GetCapabilities GetCapabilities1)
    {
        GetCapabilitiesRequest inValue = new GetCapabilitiesRequest();
        inValue.GetCapabilities = GetCapabilities1;
        GetCapabilitiesResponse retVal = ((HMA_OrderingBinding)(this)).GetCapabilities(inValue);
        return retVal.Capabilities;
    }
}

最佳答案

两个问题:

为什么要创建一个包含子对象GetCapabilitiesRequest的GetCapabilities对象，然后在您的方法调用中仅使用包含的子对象GetCapabilities？

那么，为什么不首先创建GetCapabilities而不考虑包装对象呢？

另外，您也可以向展示GetCapabilitiesRequest和GetCapabilities以及返回类Capabilities吗？如果您有反序列化错误，则最有可能是那些类不正确的问题...

更新:，感谢您对问题的更新...。
嗯...乍一看似乎找不到任何明显的错误....

关于您的问题:

我不明白的是
GetCapabilities需要一个
GetCapabilitiesRequest参数，但是
当我实现客户时，我的
智慧要求
OSEOP.GetCapabilities对象。

是的，这很清楚-您的服务端使用其类集-GetCapabilitiesRequest等。

当您在Visual Studio中执行Add Service Reference时，VS的作用是

询问服务器以了解服务-它具有什么方法以及需要哪些参数

它为客户端代理创建了一组复制您的类的-在您在Add Service Reference对话框上定义的 namespace 中。这些类看起来与服务器端类完全相同-但是它们是而不是相同的类-它们只是以与服务器端相同的方式序列化为XML(并从XML反序列化)。这就是为什么您的客户端代理在不同的 namespace 中具有不同的类。这是标准的WCF行为-不用担心...

更新编号。 2 :Carlos，您发送给我的架构似乎不完整或有错误。尝试使用OGC project on CodePlex作为基础并手动构建代码，或者等到架构“正式”发布。
