如何序列化List <object>
我正在编写通用函数来序列化给定对象和List <object>，如下所示
public string SerializeObject(Object pObject)// for given object
{
try
{
String XmlizedString = null;
MemoryStream memoryStream = new MemoryStream();
XmlSerializer xs = new XmlSerializer(typeof(pObject));
XmlTextWriter xmlTextWriter = new XmlTextWriter(memoryStream, Encoding.UTF8);
xs.Serialize(xmlTextWriter, pObject);
memoryStream = (MemoryStream)xmlTextWriter.BaseStream;
XmlizedString = UTF8ByteArrayToString(memoryStream.ToArray());
return XmlizedString;
}
catch (Exception e) { System.Console.WriteLine(e); return null; }
}
public string SerializeObject(List<Object> pObject)// for given List<object>
{
try
{
String XmlizedString = null;
MemoryStream memoryStream = new MemoryStream();
XmlSerializer xs = new XmlSerializer(typeof(pObject));
XmlTextWriter xmlTextWriter = new XmlTextWriter(memoryStream, Encoding.UTF8);
xs.Serialize(xmlTextWriter, pObject);
memoryStream = (MemoryStream)xmlTextWriter.BaseStream;
XmlizedString = UTF8ByteArrayToString(memoryStream.ToArray());
return XmlizedString;
}
catch (Exception e) { System.Console.WriteLine(e); return null; }
}
第一个工作正常。 如果我传递任何类型，它成功返回xml字符串。
更正：第二个编译错误发生（错误：无法从List<MyType>转换为List<object> 。
我重写了第二个，解决了我的问题。 现在它正在序列化给定的List<generic types> 。
private string SerializeObject<T>(T source)
{
MemoryStream memoryStream = new MemoryStream();
XmlSerializer xs = new XmlSerializer(typeof(T));
XmlTextWriter xmlTextWriter = new XmlTextWriter(memoryStream, Encoding.UTF8);
xs.Serialize(xmlTextWriter, source);
memoryStream = (MemoryStream)xmlTextWriter.BaseStream;
string XmlizedString = UTF8ByteArrayToString(memoryStream.ToArray());
return XmlizedString;
}

文章中的相关代码：
private static string SerializeObject<T>(T source)
{
var serializer = new XmlSerializer(typeof(T));
using (var sw = new System.IO.StringWriter())
using (var writer = XmlWriter.Create(sw))
{
serializer.Serialize(writer, source);
return sw.ToString();
}
}
我已经尝试过你的两个功能，没有太大麻烦。 我改变的唯一的东西是这一行：
XmlSerializer xs = new XmlSerializer(typeof(pObject));
对此：
XmlSerializer xs = new XmlSerializer(pObject.GetType());
typeof（）需要一个实际类型，而GetType（）则返回该对象的类型。
