C# 为什么响应对象中的所有项都为空？

我目前编写了一个与SOAP Web服务交互的WCF客户机。 我的问题是我的响应对象总是保持零，即使是简单的类型。 没有例外

WSDL位置：

关于您的类：商户、应用程序、错误等。在类声明上方添加

[DataContract]

，在所有属性上方添加

[DataMember]

，如：

[DataContract]
public class Merchant
{
    [DataMember] 
    public int SomeVariable { get; set; }

    ...
}

---

另外，我注意到您的

MessageBodyMember

名称和类名之间存在一些大小写差异，您是否尝试将它们更改为相同的名称？

好的，我刚刚发现错误，我再次查看了xml响应。其中所有属性都没有命名空间。这一点必须明确说明

SOAP响应

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="urn:BillSAFE">

<SOAP-ENV:Body>

这不起作用。我已经测试过了吗。Show：甚至response.ACK也为null。有时，如果客户端和服务器之间生成的内容不匹配，命名空间（如C#命名空间）可能会导致问题。如果ServiceContract属性的Namespace属性与服务器上的属性不匹配，则可能会导致类似的问题。确保您的命名空间在客户端和服务器之间全面同步。无论您使用的是哪种属性（ServiceContract、MessageBodyMember等），我现在都有这个问题，最多3天。我已经对名称空间进行了10次测试。也就是说，请求的工作没有问题，只是响应似乎没有被填充。此外，一旦配置属性callbackDebug.includeExceptionDetailInFaults启用，将生成异常。您添加的示例没有显示您如何尝试将[DataContract]等添加到类和属性中。你能用一个这样的例子来替换TestMethod吗？当你在做的时候，移除那些try/catch块

try{…}catch（Exception）{throw；}

与

..

是一回事，但不会浪费那么多时间。
