namespace ConsoleApplication1

{

class Program

{

static void Main(string[] args)

{

var f = new XmlSerializer(typeof(TestClass));

using (var sw = new StringWriter())

{

f.Serialize(sw, new TestClass());

using (var sr = new StringReader(sw.ToString()))

{

var bt = (TestClass) f.Deserialize(sr);

Console.WriteLine(bt.ListIdentical());

}

public class TestClass

{

private List<int> PrivateList;

public List<int> MyList;

public bool ListIdentical()

{

return PrivateList == MyList;

}

public TestClass()

{

PrivateList = new List<int>() { 123, 567 };

MyList = PrivateList;

}

运行结果为 True 。实际上，如果把 MyList 换成只读属性，只要其值非 null / Nothing，则程序仍可以正常运行。

也就是说，反序列化过程复用了已有的集合实例。继续阅读“XmlSerializer 测试 2”
