返回肥皂信封缺失值

标签： c# soap wsdl generic-collections

我有一个Soap WSDL，在我的应用程序中设置为指向.asmx文件的服务引用。我的响应肥皂信封问题。我有一个集合对象，当它在我的接收代码上创建时，值就在那里。当我逐步完成代码到soap包围现在是一个内存流并且即将被发送回调用客户端时，将填充该集合。然而，还有一次按F10并且我回到了调用客户端，收集了空集。

这是我正在使用的类的WSDL：

StepInstances是专注于我的问题的集合。如您所见，它按预期填充。

进入MemoryStream后，它会被发送回调用客户端。我在其中查看对象，StepInstances为null。

另请注意，我发布的WSDL是一部分，主要是违规类。返回的信封是一个包含这些类的更大的类，并且发布的内容太多了。

但是我从接收客户端进入内存流的最后一段代码已填充。接下来的f10我用我的对象回到了我的调用客户端，收集为空。

希望这是有道理的，有人可以对此有所了解。您需要的更多数据我将尝试发布。

另外值得注意的是，我有权访问的是.wsdl文件，而不是实际的WCF项目或类。

配置我的服务参考：对于集合类型，我选择了Generic.List，而字典类型I选择了Generic.Dictionary。

更新：wsdl中的APIObject看起来像这样

    <complexType name="APIObject">
    <sequence>
      <element name="Client" type="tns:ClientID" minOccurs="0" maxOccurs="1"></element>
      <element name="PartnerKey" type="xsd:string" nillable="true" minOccurs="0" maxOccurs="1"></element>
      <element name="PartnerProperties" type="tns:APIProperty" minOccurs="0" maxOccurs="unbounded"></element>
      <element name="CreatedDate" type="xsd:dateTime" minOccurs="0" maxOccurs="1"></element>
      <element name="ModifiedDate" type="xsd:dateTime" minOccurs="0" maxOccurs="1" nillable="true"></element>
      <element name="ID" type="xsd:int" minOccurs="0" maxOccurs="1"></element>
      <element name="ObjectID" type="xsd:string" nillable="true" minOccurs="0" maxOccurs="1"></element>
      <element name="CustomerKey" type="xsd:string" minOccurs="0" maxOccurs="1"></element>
      <element name="Owner" type="tns:Owner" minOccurs="0" maxOccurs="1"></element>
      <element name="CorrelationID" minOccurs="0" type="xsd:string" />
      <element name="ObjectState" type="xsd:string" minOccurs="0" maxOccurs="1"></element>
      <element name="IsPlatformObject" minOccurs="0" maxOccurs="1" type="xsd:boolean" />
    </sequence>
  </complexType>

更新＃2：我猜错了它是WCF，我只能访问.wsdl文件，编译后我将服务引用指向.asmx文件。

1 个答案:

答案 0 :(得分：0)

我已经看到了各种SOAP客户端应用程序的问题，就像您描述的那样，当序列化为SOAP响应的原始类是直接对象引用而不使用Getter / Setter属性时。所以如果你做的事情如下：

[Serializable()]
public List<StepInstance> StepInstances = new List<StepInstance>;

...

[Serializable()]
public class StepInstance {
    public string PartnerKey = "";
    public string ObjectID = "";
}

...对于某些类型的客户，这有时似乎不适用。相反，确保对象使用公共getter / setter方法，并且在客户端反序列化对象时出现的问题可能会很快消失。不知道为什么会这样，但似乎对某些类型的SOAP客户端产生了影响。所以我们上面的例子看起来更像是：

[Serializable()]
public List<StepInstance> StepInstances { get { return mStepInstances; } { set { mStepInstances = value; } }

private List<StepInstance> mStepInstances = new List<StepInstance>;

...

[Serializable()]
public class StepInstance {
    private string msPartnerKey = "";
    private string msObjectID = "";

    public string PartnerKey { get { return msPartnerKey; } set { msPartnerKey = value; } }
    public string ObjectID { get { return msObjectID; } set { msObjectID = value; } }
}
