C# XmlSerializer不包括非字符串元素

这来自WSDL文档：

<s:complexType name="ResponseMsg">
<s:all>
<s:element minOccurs="0" maxOccurs="1" name="Responsestatus" type="s:string" />
<s:element minOccurs="0" maxOccurs="1" name="CurBalance" type="s:double" />
<s:element minOccurs="0" maxOccurs="1" name="AvlBalance" type="s:double" />
<s:element minOccurs="1" maxOccurs="1" name="Acknowledgement" type="s:string" />
<s:element minOccurs="0" maxOccurs="1" name="LoadAmount" type="s:double" />
<s:element minOccurs="0" maxOccurs="1" name="Bill_Amt_Approved" type="s:double" />
<s:element minOccurs="0" maxOccurs="1" name="Update_Balance" type="s:int" />
<s:element minOccurs="0" maxOccurs="1" name="New_Balance_Sequence_Exthost" type="s:long" />
<s:element minOccurs="0" maxOccurs="1" name="CVV2_Result" type="s:string" /> <s:element minOccurs="0" maxOccurs="1" name="AvlBalance_GPS_STIP" type="s:double" /> <s:element minOccurs="0" maxOccurs="1" name="CurBalance_GPS_STIP" type="s:double" />
</s:all>
</s:complexType>

但是结果字符串是

<?xml version="1.0" encoding="utf-16"?>
<ResponseMsg>
  <Responsestatus xmlns="http://tempuri.org/">00</Responsestatus>
  <Acknowledgement xmlns="http://tempuri.org/">1</Acknowledgement>
  <CVV2_Result xmlns="http://tempuri.org/">test</CVV2_Result>
</ResponseMsg>

00
1.
测试

我设置值的其他字段在哪里？只显示字符串类型，缺少的是双精度

另外，如何去掉每个元素上的xmlns？

您是否看到以“Specified”结尾的属性？这些属性是存在的，因此可以区分“属性存在”和“属性缺失”两种情况。对于字符串属性，

！=null

或

==null

因此，对于非字符串属性，如果希望序列化值，则需要将…指定的属性设置为true：

var rtnAck = new ResponseMsg
{
    Responsestatus = "00",
    CurBalance = 0.5,
    CurBalanceSpecified = true,
    AvlBalance = 0.5,
    AvlBalanceSpecified = true, 
    Acknowledgement = "1",
    LoadAmount = 0.00,
    LoadAmountSpecified = true,
    CVV2_Result = "test"
};

---

这对用户不是很友好，但是XmlSerialization早于

Nullable

对于额外的问题，请参见此处：您有以下可以删除的属性：System.Xml.Serialization.XmlIgnoreAttribute（）@jdweng XmlIgnoreAttribute是Visual Studio自动生成的代码的一部分（通过添加服务参考选项）那又怎么样！！！Microsoft tools没有做你想让它做的事情。我试图找到阻止不想要的结果的选项。我花了几个月（也许几年）试图阻止Microsoft tools做错误的事情。

var rtnAck = new ResponseMsg
{
    Responsestatus = "00",
    CurBalance = 0.5,
    AvlBalance = 0.5,
    Acknowledgement = "1",
    LoadAmount = 0.00,
    CVV2_Result = "test"
};

var rtnData = rtnAck.ObjectToXml();

<?xml version="1.0" encoding="utf-16"?>
<ResponseMsg>
  <Responsestatus xmlns="http://tempuri.org/">00</Responsestatus>
  <Acknowledgement xmlns="http://tempuri.org/">1</Acknowledgement>
  <CVV2_Result xmlns="http://tempuri.org/">test</CVV2_Result>
</ResponseMsg>

var rtnAck = new ResponseMsg
{
    Responsestatus = "00",
    CurBalance = 0.5,
    CurBalanceSpecified = true,
    AvlBalance = 0.5,
    AvlBalanceSpecified = true, 
    Acknowledgement = "1",
    LoadAmount = 0.00,
    LoadAmountSpecified = true,
    CVV2_Result = "test"
};
