对实体类做标记
[DataContract] 标记在class前。
[DataMember] 标记在需要保存的属性前。
1 [DataContract]
2public class Car
3{
4 [DataMember]
5 public string name;
6
7 [DataMember]
8 double power;
9
10 [DataMember]
11 List<Wheel> wheels;
12}
拷贝这两个函数
保存：保存文件到xml，文件目录和程序目录相同，文件名自定。
读取：从指定文件名读取。
1static void SaveViaDataContractSerialization<T>(T serializableObject, string filepath)
2{
3 var serializer = new DataContractSerializer(typeof(T));
4 var settings = new XmlWriterSettings()
5 {
6 Indent = true,
7 IndentChars = "\t",
8 };
9 var writer = XmlWriter.Create(filepath, settings);
10 serializer.WriteObject(writer, serializableObject);
11 writer.Close();
12}
13
14
15static T LoadViaDataContractSerialization<T>(string filepath)
16{
17 var fileStream = new FileStream(filepath, FileMode.Open);
18 var reader = XmlDictionaryReader.CreateTextReader(fileStream, new XmlDictionaryReaderQuotas());
19 var serializer = new DataContractSerializer(typeof(T));
20 T serializableObject = (T)serializer.ReadObject(reader, true);
21 reader.Close();
22 fileStream.Close();
23 return serializableObject;
24}
读取方法
使用上面两个方法来读取和存储
1// Save single object
2Car bmw = new Car("BMW", 200, new List<string> { "Left", "Right" }); // create object
3SaveViaDataContractSerialization(bmw, "bmw.xml"); // save object
4bmw = null; // delete object
5bmw = LoadViaDataContractSerialization<Car>("bmw.xml"); // reload object
6Console.WriteLine(bmw.ToString()); // print object
7
8
9// Save list of objects
10List<Car> carList = new List<Car> // create object list
11{
12new Car("Porsche", 250, new List<string> { "Left" }),
13new Car("Mercedes", 150, new List<string> { "Front", "Back" }),
14new Car("Aston Martin", 300, new List<string> { "Front" })
15};
16SaveViaDataContractSerialization(carList, "cars.xml"); // save object list
17carList = null; // delete object list
18carList = LoadViaDataContractSerialization<List<Car>>("cars.xml"); // reload object list
19foreach (var a in carList) // print object list
20Console.WriteLine(a.ToString());
21
22Console.ReadLine();
