私はこれに対する決定的な反応を見つけることができないようで、それは私を夢中にさせています。XmlSerializerクラスは、定義されているものすべてに対して、さらにはネストされたクラスに対してもうまく機能するようです。ただし、クラスの1つにSystem.Objectが含まれていると、それは嘔吐します。誰かがこれを回避する簡単な方法を知っていますか?
namespace test
{
public class SomeList
{
public object obj;
}
public class Person
{
public string first;
public string last;
}
class Program
{
static void Main(string[] args)
{
try
{
Console.WriteLine("Creating object...");
Person me = new Person();
me.first = "MyFirst";
me.last = "MyLast";
Console.WriteLine("- Serialized: " + serialize_xml<Person>(me));
Console.WriteLine("");
Console.WriteLine("Creating object with embedded generic...");
SomeList test = new SomeList();
test.obj = me;
Console.WriteLine("- Serialized: " + serialize_xml<SomeList>(test));
Console.WriteLine("");
Console.Write("Press ENTER to exit.");
Console.ReadLine();
return;
}
catch (Exception e)
{
print_exception(e);
Console.WriteLine("");
Console.Write("Press ENTER to exit.");
Console.ReadLine();
return;
}
}
static string serialize_xml<T>(T obj)
{
XmlSerializer xmls = new XmlSerializer(typeof(T));
using (MemoryStream ms = new MemoryStream())
{
XmlWriterSettings settings = new XmlWriterSettings();
XmlSerializerNamespaces ns = new XmlSerializerNamespaces();
ns.Add("", "");
settings.Encoding = Encoding.UTF8;
settings.Indent = false;
settings.NewLineChars = "";
settings.NewLineHandling = NewLineHandling.None;
settings.NewLineOnAttributes = false;
settings.ConformanceLevel = ConformanceLevel.Document;
settings.OmitXmlDeclaration = true;
using (XmlWriter writer = XmlTextWriter.Create(ms, settings))
{
xmls.Serialize(writer, obj, ns);
}
string xml = Encoding.UTF8.GetString(ms.ToArray());
// remove the BOM character at the beginning which screws up decoding
if (xml.Length > 0 && xml[0] != '<')
{
xml = xml.Substring(1, xml.Length - 1);
}
return xml;
}
}
static void print_exception(Exception e)
{
Console.WriteLine(" = Exception Type: " + e.GetType().ToString());
Console.WriteLine(" = Exception Dat " + e.Data);
Console.WriteLine(" = Inner Exception: " + e.InnerException);
Console.WriteLine(" = Exception Message: " + e.Message);
Console.WriteLine(" = Exception Source: " + e.Source);
Console.WriteLine(" = Exception StackTrace: " + e.StackTrace);
}
}
}
コンソールに次の出力を作成します。
