如何反序列化此XML文档:
<?xml version="1.0" encoding="utf-8"?> <Cars> <Car> <StockNumber>1020</StockNumber> <Make>Nissan</Make> <Model>Sentra</Model> </Car> <Car> <StockNumber>1010</StockNumber> <Make>Toyota</Make> <Model>Corolla</Model> </Car> <Car> <StockNumber>1111</StockNumber> <Make>Honda</Make> <Model>Accord</Model> </Car> </Cars>
我有这个:
[Serializable()] public class Car { [System.Xml.Serialization.XmlElementAttribute("StockNumber")] public string StockNumber{ get; set; } [System.Xml.Serialization.XmlElementAttribute("Make")] public string Make{ get; set; } [System.Xml.Serialization.XmlElementAttribute("Model")] public string Model{ get; set; } }
。
[System.Xml.Serialization.XmlRootAttribute("Cars", Namespace = "", IsNullable = false)] public class Cars { [XmlArrayItem(typeof(Car))] public Car[] Car { get; set; } }
public class CarSerializer { public Cars Deserialize() { Cars[] cars = null; string path = HttpContext.Current.ApplicationInstance.Server.MapPath("~/App_Data/") + "cars.xml"; XmlSerializer serializer = new XmlSerializer(typeof(Cars[])); StreamReader reader = new StreamReader(path); reader.ReadToEnd(); cars = (Cars[])serializer.Deserialize(reader); reader.Close(); return cars; } }
似乎不起作用:-(
这是工作版本。我将XmlElementAttribute标签更改为,XmlElement因为在xml中StockNumber,Make和Model值是元素,而不是属性。我也删除了reader.ReadToEnd();(该函数读取整个流并返回一个字符串,因此该Deserialize()函数不再使用读取器…该位置位于流的末尾)。我也对命名使用了一些自由:)。
XmlElementAttribute
XmlElement
reader.ReadToEnd();
Deserialize()
这些是类:
[Serializable()] public class Car { [System.Xml.Serialization.XmlElement("StockNumber")] public string StockNumber { get; set; } [System.Xml.Serialization.XmlElement("Make")] public string Make { get; set; } [System.Xml.Serialization.XmlElement("Model")] public string Model { get; set; } } [Serializable()] [System.Xml.Serialization.XmlRoot("CarCollection")] public class CarCollection { [XmlArray("Cars")] [XmlArrayItem("Car", typeof(Car))] public Car[] Car { get; set; } }
反序列化功能:
CarCollection cars = null; string path = "cars.xml"; XmlSerializer serializer = new XmlSerializer(typeof(CarCollection)); StreamReader reader = new StreamReader(path); cars = (CarCollection)serializer.Deserialize(reader); reader.Close();
略微调整的xml(我需要添加一个新元素来包装 … Net对于反序列化数组很挑剔):
<?xml version="1.0" encoding="utf-8"?> <CarCollection> <Cars> <Car> <StockNumber>1020</StockNumber> <Make>Nissan</Make> <Model>Sentra</Model> </Car> <Car> <StockNumber>1010</StockNumber> <Make>Toyota</Make> <Model>Corolla</Model> </Car> <Car> <StockNumber>1111</StockNumber> <Make>Honda</Make> <Model>Accord</Model> </Car> </Cars> </CarCollection>
