Question

我有POCO，就像

一样简单

public partial class Member
{

    public int ID { get; set; }

    [Required]
    [StringLength(100)]
    public string MemberId { get; set; }

    public DateTime CreatedOn { get; set; }

    [Required]
    [StringLength(100)]
    public string FirstName { get; set; }}

和一个看起来像这样的添加命令

   public class AddMemberCommand : ICommand
{
    public AddMemberCommand(Member member  )
    {
        ID = Guid.NewGuid();
        MemberData = member;
    }


    public  Member MemberData { get; private set; }

    public Guid ID { get; }


    public string CommandName
    {
        get { return "AddMemberCommand"; }

    }
}

继承自

public interface ICommand
{
    /// <summary>
    /// Gets the command identifier.
    /// </summary>
    Guid ID { get; }

    string CommandName { get; }
}

现在我将此代码发送到一个方法，该方法使用一些参数初始化Newton Json的序列化设置类以返回一个对象。序列化器看起来像这样

    public class JsonTextSerializer 
{
    private readonly JsonSerializer _serializer;

    public JsonTextSerializer()
    {
        _serializer = JsonSerializer.Create(new JsonSerializerSettings
        {
            TypeNameHandling = TypeNameHandling.All,
            ReferenceLoopHandling = ReferenceLoopHandling.Ignore,
            TypeNameAssemblyFormat = FormatterAssemblyStyle.Simple
        });
    }

    public void Serialize(TextWriter writer, object graph)
    {
        var jsonWriter = new JsonTextWriter(writer);
        jsonWriter.Formatting = Formatting.Indented;
        _serializer.Serialize(jsonWriter, graph);
        writer.Flush();
    }

    public object Deserialize(TextReader reader)
    {
        var jsonReader = new JsonTextReader(reader);

        try
        {
            return this._serializer.Deserialize(jsonReader);
        }
        catch (JsonSerializationException e)
        {
            // Wrap in a standard .NET exception.
            throw new SerializationException(e.Message, e);
        }
    }
}

序列化程序用于将命令转换为代理消息的有效负载，如下所示

        private BrokeredMessage CreateMessage(POCOS.Member member)
    {
        var serializer = new JsonTextSerializer();
        var command = new AddMemberCommand(member);
        var stream = new MemoryStream();
        var writer = new StreamWriter(stream);
        serializer.Serialize(writer, command);
        stream.Position = 0;
        BrokeredMessage message = new BrokeredMessage(stream, true);
        return message;

    }

并且还有另一种接收方法的方法

   private POCOS.Member GetPocoFromMessage(BrokeredMessage message)
    {
        ITextSerializer serializer = new JsonTextSerializer();
        AddMemberCommand command;

        using (var stream = message.GetBody<Stream>())
        {
            using (var reader = new StreamReader(stream))
            {
                var payload = serializer.Deserialize(reader);
                command = payload as AddMemberCommand;
            }
        }

        return command.MemberData;
    }

问题在于反序列化某些属性（ ID，CommandName ）是否已填充值 MemberData 这是null。我可以读取流（通过执行reader.ReadToEnd（））并看到它是通过线路传输但Json无法反序列化其所有对象曾经有一段时间我也认为它可能只选择界面中的字段，但事实并非如此

Answer 1

您的MemberData酒店有私人二手商家。由于序列化程序需要从外部访问该属性，因此该setter应该是公共的。

Json没有序列化Azure
