C＃，WebAPI-XML序列

如何解决C＃，WebAPI-XML序列

    [CollectionDataContract(Namespace = "http://schemas.datacontract.org/2004/07/ServicesTools.WebServices")]
    public class AcquisitionDetails : List<Acquisition>
    {


    }


    [DataContract(Name = "Acquisition",Namespace = "http://schemas.datacontract.org/2004/07/ServicesTools.WebServices")]
    public class Acquisition
    {
        [DataMember]
        public string GeoCode { get; set; }

        [DataMember]
        public string OrderDate { get; set; }

        [DataMember]
        public string supplier { get; set; }

        [DataMember]
        public string PartNo { get; set; }

        [DataMember]
        public int QtyExpected { get; set; }

        [DataMember]
        public uint PONumber { get; set; }

    }

在另一个问题中，我们使此XML工作：

<?xml version="1.0" encoding="utf-8"?>
<AcquisitionDetails>
  <Acquisition>
    <GeoCode>PHX</GeoCode>
    <OrderDate>3/10/2020 12:00:00 AM</OrderDate>
    <PartNo>20L6S52C11</PartNo>
    <QtyExpected>71</QtyExpected>
    <PONumber>1990001996</PONumber>
    <supplier>Lenovo (International) BV</supplier>
  </Acquisition>
</AcquisitionDetails>

控制器中的代码：

        [Consumes("application/xml")]
        [Produces("application/xml")]
        [HttpPost]
        public ActionResult Post(AcquisitionDetails ad)
        {
            return Ok(ad);
        }

但是，有一个；

当我在POSTMAN中发送此邮件时，例如PONumber为空

<AcquisitionDetails xmlns:i="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://schemas.datacontract.org/2004/07/ServicesTools.WebServices">
    <Acquisition>
        <GeoCode>PHX</GeoCode>
        <OrderDate>3/10/2020 12:00:00 AM</OrderDate>
        <PONumber>0</PONumber>
        <PartNo>20L6S52C11</PartNo>
        <QtyExpected>71</QtyExpected>
        <supplier>Lenovo (International) BV</supplier>
    </Acquisition>
</AcquisitionDetails>

是这种情况，直到我将其向上移动一点，但是

    <Acquisition>
        <GeoCode i:nil="true" />
        <OrderDate i:nil="true" />
        <PONumber>1990001996</PONumber>
        <PartNo>20L6S52C11</PartNo>
        <QtyExpected>71</QtyExpected>
        <supplier>Lenovo (International) BV</supplier>
    </Acquisition>

总之，长话短说。我无法更改传入XML的顺序，也不想被迫按所述顺序接收XML；我不能更改传入XML的顺序。如何指示模型解析XML呢？

========更新=====

    [DataContract(Name = "Acquisition",Namespace = "http://schemas.datacontract.org/2004/07/ServicesTools.WebServices")]
    public class Acquisition
    {
        [DataMember(Name = "GeoCode")]
        public string GeoCode { get; set; }

        [DataMember(Name = "OrderDate")]
        public string OrderDate { get; set; }

        [DataMember(Name = "supplier")]
        public string supplier { get; set; }

        [DataMember(Name = "PartNo")]
        public string PartNo { get; set; }

        [DataMember(Name = "QtyExpected")]
        public int QtyExpected { get; set; }

        [DataMember(Name = "PONumber")]
        public Int64 PONumber { get; set; }

    }

但是结果仍然是：

输入：

<?xml version="1.0" encoding="utf-8"?>
<AcquisitionDetails xmlns="http://schemas.datacontract.org/2004/07/ServicesTools.WebServices">
  <Acquisition>
    <GeoCode>PHX</GeoCode>
    <OrderDate>3/10/2020 12:00:00 AM</OrderDate>
    <PONumber>1990001996</PONumber>
    <PartNo>20L6S52C11</PartNo>
    <QtyExpected>71</QtyExpected>
    <supplier>Lenovo (International) BV</supplier>
  </Acquisition>
  <Acquisition>
    <GeoCode>PHX</GeoCode>
    <OrderDate>3/9/2020 12:00:00 AM</OrderDate>
    <PartNo>AA549668</PartNo>
    <QtyExpected>20</QtyExpected>
    <PONumber>1990001879</PONumber>
    <supplier>SHI INTERNATIONAL CORP</supplier>
  </Acquisition>
</AcquisitionDetails>

输出：

<AcquisitionDetails xmlns:i="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://schemas.datacontract.org/2004/07/ServicesTools.WebServices">
    <Acquisition>
        <GeoCode>PHX</GeoCode>
        <OrderDate>3/10/2020 12:00:00 AM</OrderDate>
        <PONumber>1990001996</PONumber>
        <PartNo>20L6S52C11</PartNo>
        <QtyExpected>71</QtyExpected>
        <supplier>Lenovo (International) BV</supplier>
    </Acquisition>
    <Acquisition>
        <GeoCode>PHX</GeoCode>
        <OrderDate>3/9/2020 12:00:00 AM</OrderDate>
        <PONumber>0</PONumber>
        <PartNo>AA549668</PartNo>
        <QtyExpected>20</QtyExpected>
        <supplier>SHI INTERNATIONAL CORP</supplier>
    </Acquisition>
</AcquisitionDetails>

解决方法

您要订购吗？我不确定，但可能会对您有帮助

encapsulation: ViewEncapsulation.None

,

在Name属性中为所有参数指定DataMember-参数的顺序无关紧要。例如：

    public class Acquisition
    {
        [DataMember(Name = "GeoCode"]
        public string GeoCode { get; set; }
    }
