[Mono-devel-list] Deserialization (reflection) bug

[Herscovici, Avi]

Hi guys + lluis,

  Got a new deserialization bug.  I've pasted code.  Problem goes away when
I get rid of the second Add method in obj1 class.  Seems like reflection
doesn't like overloaded methods?  May also have to do with implementing
CollectionBase.  I think I've had the exact same problem that came from the
XmlSerializer constructor (that Lluis fixed) with an example that
implemented collectionbase, but now it is coming from deserialize. Either
way here are the files and the error:


// --------------test.cs---------------
using System;
using System.Xml.Serialization;
using System.IO;
using System.Xml;
using Test;


namespace Serial.test {

public class sertest {

		public static void Save(System.IO.Stream stream, object x)
		{
			XmlSerializer ser = new XmlSerializer(typeof(obj1));
			ser.Serialize(stream, x);
		}

		public static void Save(string filename, object x)
		{
			FileStream str = new FileStream(filename,
FileMode.Create, FileAccess.Write);
			Save(str, x);
			str.Close();
		}

		public static object Load(System.IO.Stream stream)
		{
			object s;
			Console.WriteLine("Debug line 1a");
			XmlSerializer ser = new XmlSerializer(typeof(obj1));
			Console.WriteLine("Debug line 2a");
			s = (object)ser.Deserialize(stream);
			return s;
		}


		public static object Load(string filename)
		{
				object s;
				Console.WriteLine("Debug line 2");
				FileStream str = new FileStream(filename,
FileMode.Open, FileAccess.Read);
				Console.WriteLine("Debug line 3");
				s = Load(str);
				Console.WriteLine("Debug line 4");
				str.Close();
				return s;
		}

	static void Main() {
	string filename = "st4.ser";
	obj1 x =  new obj1();
	x.Add(new obj2());
	Save(filename, x);
	obj1 temp = (obj1)Load(filename);
	Console.WriteLine("Finished");
	}
}
}
