WCF XML反序列化不填充数组

Question

我使用 VS 2017 Pro (C#) 针对 .Net 4.5.1 开发了一个 WCF 该服务接受 SOAP 请求中的 XML 对象。
我遇到的问题是 XML 中有一个未反序列化的数组。 WCF 正在使用本机反序列化程序。下面的代码和 XML 示例。

XML标签Application->Amount反序列化ok

XML 标记 Application_SAList->Application_SA->SecurityKey> 没有

ApplicationImpl.Application_SAList业务逻辑空检查通过，但ApplicationImpl.Application_SAList.Application_SA数组长度为0

所有类都有'using System.Runtime.Serialization;'

急于解决这个问题！提前感谢任何人的帮助！

IApplicationService.cs

namespace TApplicationService
{
    [ServiceContract(Namespace = "http://xyz")]
    public interface IApplicationService
    {

        [OperationContract(Name="ProcessApplication")]
        string ProcessApplication(ApplicationRequestImpl ApplicationRequestImpl);
    }
}

ApplicationService.svc.cs

namespace ThriventApplicationService
{

    [ServiceBehavior(Namespace = "http://xyz")]
    public class ApplicationService : IApplicationService
    {
        private SDatabase gDatabase = null;

        public string ProcessApplication(ApplicationRequestImpl ApplicationRequestImpl)
        {
          // does a bunch of business logic here
        }
}

ApplicationRequestImpl.cs

namespace ThriventApplicationService
    {

        [DataContract(Namespace = "http://xyz")]
        public class ApplicationRequestImpl
        {
            [DataMember]
            public Application Application;

            [DataMember(Name="Application_SAList")]
            public ApplicationSASingle Application_SAList;
        }
    }

应用程序.cs

namespace ThriventApplicationService
{
    [DataContract(Namespace = "http://xyz")]
    public class Application : IExtensibleDataObject
    {

        [DataMember]
        public string Amount;
    }
}

Application_SASingle.cs

namespace ThriventApplicationService
{
    [DataContract(Namespace = "http://xyz")]
    public class ApplicationSASingle
    {
        [DataMember]
        public Application_SA[] Application_SA;
    }
}

Application_SA.cs

namespace ThriventApplicationService
{
    [DataContract(Namespace = "http://xyz")]
    public class Application_SA
    {
        [DataMember]
        public string Security_Key;
    }
}

示例 XML

<ProcessApplication xmlns="http://xyz">
    <ApplicationRequestImpl>
        <Application>
            <Amount>50000.0</Amount>
        </Application>
        <Application_SAList>
            <Application_SA>
                <Security_Key>1588</Security_Key>
            </Application_SA>
        </Application_SAList>
    </ApplicationRequestImpl>
</ProcessApplication>

ApplicationRequestImpl.cs 中的解决方案

   [DataContract(Namespace = "http://prosurv")]
    public class ApplicationRequestImpl
    {

        [DataMember]
        public Application Application;

        [DataMember(Name="Application_SAList")]
        //public Application_SAList Application_SAList;
        public Application_SA[] Application_SA;
}

又一次拍摄后，我找到了解决方案。问题在于ApplicationRequestImpl 类。 XML rerader 正在寻找 Application_SA 内不存在的 Application_SA 元素。

[DataContract(Namespace = "http://xyz")]
public class ApplicationRequestImpl
{
    [DataMember]
    public Application Application;

    //Remove these two lines
    //[DataMember(Name="Application_SAList")]
    //public ApplicationSASingle Application_SAList;

    [DataMember]
    public Application_SA[] Application_SAList;
}

数组的问题是它们需要知道它们的大小。其中初始化时为0。等于：

public Application_SA[] Application_SA = new Application_SA[0];

反序列化的对象没有空间容纳。

解决方案是切换到：

public List<Application_SA> Application_SA = new List<Application_SA>();

希望对你有帮助。
