示例
下面的示例演示了一个名为 WriteObjectWithInstance 包含 XmlObjectSerializer 参数的方法。 该方法使用 DataContractSerializer 或 NetDataContractSerializer 调用 WriteObject 方法序列化对象。
public class Test
{
private void WriteObjectWithInstance(XmlObjectSerializer xm, Company graph,
string fileName)
{
// Use either the XmlDataContractSerializer or NetDataContractSerializer,
// or any other class that inherits from XmlObjectSerializer to write with.
Console.WriteLine(xm.GetType());
FileStream fs = new FileStream(fileName, FileMode.Create);
XmlDictionaryWriter writer = XmlDictionaryWriter.CreateTextWriter(fs);
xm.WriteObject(writer, graph);
Console.WriteLine("Done writing {0}", fileName);
}
private void Run()
{
// Create the object to write to a file.
Company graph = new Company();
graph.Name = "cohowinery.com";
// Create a DataContractSerializer and a NetDataContractSerializer.
// Pass either one to the WriteObjectWithInstance method.
DataContractSerializer dcs = new DataContractSerializer(typeof(Company));
NetDataContractSerializer ndcs = new NetDataContractSerializer();
WriteObjectWithInstance(dcs, graph, @"datacontract.xml");
WriteObjectWithInstance(ndcs, graph, @"netDatacontract.xml");
}
[DataContract]
public class Company
{
[DataMember]
public string Name;
}
static void Main()
{
try
{
Console.WriteLine("Starting");
Test t = new Test();
t.Run();
Console.WriteLine("Done");
Console.ReadLine();
}
catch (InvalidDataContractException iExc)
{
Console.WriteLine("You have an invalid data contract: ");
Console.WriteLine(iExc.Message);
Console.ReadLine();
}
catch (SerializationException serExc)
{
Console.WriteLine("There is a problem with the instance:");
Console.WriteLine(serExc.Message);
Console.ReadLine();
}
catch (QuotaExceededException qExc)
{
Console.WriteLine("The quota has been exceeded");
Console.WriteLine(qExc.Message);
Console.ReadLine();
}
catch (Exception exc)
{
Console.WriteLine(exc.Message);
Console.WriteLine(exc.ToString());
Console.ReadLine();
}
}

注解
XmlObjectSerializer扩展创建自己的序列化程序以序列化和反序列化对象。
实施者说明
从XmlObjectSerializer中继承时，必须重写以下成员：WriteStartObject(XmlDictionaryWriter, Object)、、 WriteObjectContent(XmlDictionaryWriter, Object)WriteEndObject(XmlDictionaryWriter)。 此外， IsStartObject 必须实现用于读取和反序列化的和 ReadObject 方法。
