XmlSerializer不包括非字符串元素

Question

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>

在将WSDL添加到我的Visual Studio项目(添加服务引用(之后，我得到了以下内容：

protected void RaisePropertyChanged(string propertyName) {
System.ComponentModel.PropertyChangedEventHandler propertyChanged = this.PropertyChanged;
if ((propertyChanged != null)) {
propertyChanged(this, new System.ComponentModel.PropertyChangedEventArgs(propertyName));
}
}
}

我将此代码添加到我的项目中(在其他地方找到(：

public static string ObjectToXml<T>(this T obj) where T : class
{
var settings = new XmlWriterSettings
{
Indent = true,
OmitXmlDeclaration = false,
Encoding = Encoding.GetEncoding("UTF-8")
};
var namespaces = new XmlSerializerNamespaces();
namespaces.Add(string.Empty, string.Empty);
var serializer = new XmlSerializer(obj.GetType());
using (var stringWriter = new StringWriter())
{
using (var xmlWriter = XmlWriter.Create(stringWriter, settings))
{
serializer.Serialize(xmlWriter, obj, namespaces);
}
return stringWriter.ToString();
}
}

并这样称呼它：

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

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>

我设置值的其他字段在哪里？唯一出现的是字符串类型，缺少的是双字符。

另外，我如何去掉每个元素上的xmlns？

Answer 1

您看到属性以"指定的"；？这些是存在的；属性存在"；以及"；属性丢失"；可以区分。对于字符串属性，这是由!= null或== null隐含的。

因此，对于非字符串属性，您需要设置。。。如果要序列化值，则指定的属性为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"
};

这不是很用户友好，但XmlSerialization早于Nullable<T>。
