我有一些XML需要反序列化为一个对象。大多数元素可以转换为字符串和整数,但是一个元素作为一个数字进入,我需要将其转换为三个布尔值。这是转换为布尔人的逻辑:
switch (_valFromXML)
{
case 0:
_bool1= true;
break;
case 1:
_bool2= true;
break;
case 2:
_bool1= true;
_bool2= true;
break;
case 3:
_bool3= true;
break;
case 4:
_bool1= true;
_bool3= true;
break;
case 5:
_bool2= true;
_bool3= true;
break;
case 6:
_bool1= true;
_bool2= true;
_bool3= true;
break;
}
我尝试过像这个例子中那样创建隐式运算符,但我看到的唯一被调用的是我的无参数构造函数:

以下是要反序列化的属性:
private ConvertElement _convertElement;
[XmlElement("ConvertElement", typeof(ConvertElement))]
public ConvertElement ConvertElement
{
get { return _convertElement; }
set { _convertElement= value; }
}
我可以整天反序列化为整数,但由于某种原因,我无法将元素转换为自定义类型。这是我尝试从元素创建的类:
[Serializable]
public class ConvertElement
{
int _value;
bool _bool1;
bool _bool2;
bool _bool3;
public static implicit operator int(ConvertElement x)
{
return x.Value;
}
public static implicit operator ConvertElement(int value)
{
return new ConvertElement(value);
}
public int Value
{
get { return _value; }
set { _value = value; }
}
public ConvertElement()
{
}
public DocSelection(int value)
{
_value= value;
switch (_value)
{
case 0:
_bool1= true;
break;
case 1:
_bool2= true;
break;
case 2:
_bool1= true;
_bool2= true;
break;
case 3:
_bool3= true;
break;
case 4:
_bool1= true;
_bool3= true;
break;
case 5:
_bool2= true;
_bool3= true;
break;
case 6:
_bool1= true;
_bool2= true;
_bool3= true;
break;
}
}
}

您可能必须使用IXmlSerializable
界面来执行自定义反序列化
示例:
public class ConvertElement : IXmlSerializable
{
private int _value;
private bool _bool1;
private bool _bool2;
private bool _bool3;
public ConvertElement()
{
}
#region IXmlSerializable implementation
public void WriteXml(XmlWriter writer)
{
writer.WriteValue(_value);
}
public void ReadXml(XmlReader reader)
{
_value = int.Parse(reader.ReadString());
DocSelection(_value);
}
public XmlSchema GetSchema()
{
return null;
}
#endregion
public void DocSelection(int value)
{
_value = value;
switch (_value)
{
case 0:
_bool1 = true;
break;
case 1:
_bool2 = true;
break;
case 2:
_bool1 = true;
_bool2 = true;
break;
case 3:
_bool3 = true;
break;
case 4:
_bool1 = true;
_bool3 = true;
break;
case 5:
_bool2 = true;
_bool3 = true;
break;
case 6:
_bool1 = true;
_bool2 = true;
_bool3 = true;
break;
}
}
XML:
<?xml version="1.0"?>
<TestClass xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<ConvertElement>6</ConvertElement>
</TestClass>
识别TestClass:
public class TestClass
{
private ConvertElement _convertElement;
[XmlElement("ConvertElement", typeof(ConvertElement))]
public ConvertElement ConvertElement
{
get { return _convertElement; }
set { _convertElement = value; }
}
}
序列化:
TestClass test = new TestClass
{
ConvertElement = new ConvertElement()
};
XmlSerializer xmlSerializer = new XmlSerializer(typeof(TestClass));
using (FileStream stream = new FileStream("c:\\ConvertElement.xml", FileMode.OpenOrCreate))
{
xmlSerializer.Serialize(stream, test);
}
反序列化:
XmlSerializer xmlSerializer = new XmlSerializer(typeof(TestClass));
using (FileStream stream = new FileStream("c:\\ConvertElement.xml", FileMode.Open))
{
var result = xmlSerializer.Deserialize(stream);
}
结果:
转换_value
andd设置bool值
