我正在尝试遵循有关 XML 序列化的微软教程,但我遇到了一些问题!
这是 XML 文件,用作输入:
<?xml version="1.0" encoding="utf-8"?>
<Books xmlns:books="http://www.cpandl.com" xmlns:money="http://www.cohowinery.com">
<money:Book>
<books:TITLE>A Book Title</books:TITLE>
<money:PRICE books:currency="US Dollar">
<money:price>9.95</money:price>
</money:PRICE>
</money:Book>
</Books>
这是绑定 XML 的类:
public class OrderedItem
{
[XmlElement(Namespace = "http://www.cpandl.com")]
public string ItemName;
[XmlElement(Namespace = "http://www.cpandl.com")]
public string Description;
[XmlElement(Namespace = "http://www.cohowinery.com")]
public decimal UnitPrice;
[XmlElement(Namespace = "http://www.cpandl.com")]
public int Quantity;
[XmlElement(Namespace = "http://www.cohowinery.com")]
public decimal LineTotal;
// A custom method used to calculate price per item.
public void Calculate()
{
LineTotal = UnitPrice * Quantity;
}
}
此函数将 XML 读入“OrderedItem”类:
Console.WriteLine("Reading with Stream");
// Create an instance of the XmlSerializer.
var serializer = new XmlSerializer(typeof(OrderedItem));
// Reading the XML document requires a FileStream.
Stream reader = new FileStream(filename, FileMode.Open);
// Declare an object variable of the type to be deserialized.
// Call the Deserialize method to restore the object's state.
var i = (OrderedItem)serializer.Deserialize(reader);
Console.SetOut(new StreamWriter("a_output.xml"));
serializer.Serialize(Console.Out, i);
这是读取和重写后的 XML:
<?xml version="1.0" encoding="utf-8"?>
<OrderedItem xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<ItemName xmlns="http://www.cpandl.com">Widget</ItemName>
<Description xmlns="http://www.cpandl.com">Regular Widget</Description>
<UnitPrice xmlns="http://www.cohowinery.com">2.3</UnitPrice>
<Quantity xmlns="http://www.cpandl.com">10</Quantity>
<LineTotal xmlns="http://www.cohowinery.com">23</LineTotal>
</OrderedItem>
如您所见,命名空间已扩展。我应该如何编写输出,以获得具有命名空间标签的相同 XML,而不是 uri?
