c# 序列化模型到 objectContent

Question

我有以下要序列化的类:

public class UpdateDoorCommand : IXmlSerializable
{
    // string such as D1
    public string DoorId { get; }
    public string Name { get; }
    public string Notes { get; }

    public UpdateDoorCommand(string doorId, string name, string notes)
    {
        DoorId = doorId;
        Name = name;
        Notes = notes;
    }
    public UpdateDoorCommand()
    {

    }

    public XmlSchema GetSchema()
    {
        throw new NotImplementedException();
    }

    public void ReadXml(XmlReader reader)
    {
        throw new NotImplementedException();
    }

    public void WriteXml(XmlWriter writer)
    {
        writer.WriteStartElement("Door");
        writer.WriteAttributeString("Address", "D1");
        writer.WriteElementString("Name", Name);
        writer.WriteElementString("Notes", Notes);
        writer.WriteEndElement();   
    }
}

我希望输出看起来像这样:

  <Door Address="D1">
    <Name>Name1</Name>
    <Notes>Notes1</Notes>
  </Door>

我使用以下代码序列化对象:

    [TestMethod]
    public async Task XmlSerialisationTest()
    {
        var model = new UpdateDoorCommand("D1", "Name1", "Notes1");
        var mediaTypeFormatters = new MediaTypeFormatterCollection();
        mediaTypeFormatters.XmlFormatter.UseXmlSerializer = true;
        mediaTypeFormatters.XmlFormatter.WriterSettings.OmitXmlDeclaration = true;
        var content = new ObjectContent<UpdateDoorCommand>(model, mediaTypeFormatters.XmlFormatter);
        // this does not look like the type 
        var str = await content.ReadAsStringAsync();
    }
}

但是序列化的输出没有给出预期的结果。xml 包装在具有对象类名的元素中。如何使用 ObjectContent 类获得所需的 xml 输出？

请注意，代码需要引用 System.Net.Http.Formatting 才能运行。

我不确定这两种方式是否兼容，但试试这个:

[XmlRoot(ElementName = "Door", DataType = "string")]
public class UpdateDoorCommand : IXmlSerializable
{
    // *snip*

    public void WriteXml(XmlWriter writer)
    {
        //writer.WriteStartElement("Door");
        writer.WriteAttributeString("Address", "D1");
        writer.WriteElementString("Name", Name);
        writer.WriteElementString("Notes", Notes);
        //writer.WriteEndElement();   
    }
}
