Serialization problem
Hi Every body
I have a problem and want help.
I have created a phonebook application and it works fine after a awhile i liked to make an upgrade for my application and i started from scratch i didn't inherit it from my old class,and i successes too ,my request
"I want to migrate my contacts from the old application to the
new one"
,so i made an adapter class for this reason in my new application with the following code
Code:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;
using System.Windows.Forms;
using System.Runtime.Serialization;
using System.Runtime.Serialization.Formatters.Binary;
namespace PhoneBook
{
class Adapter
{
PhoneRecord PhRecord; //the new application object
CTeleRecord TelRecord; //the old application object
string fileName;
public Adapter(string filename)
{
fileName = filename;
}
public void convert()
{
PhRecord = new PhoneRecord();
TelRecord = new CTeleRecord();
FileStream OpFileSt = new FileStream(fileName, FileMode.Open,FileAccess.Read);
BinaryFormatter readBin = new BinaryFormatter();
for (; ; )
{
try
{
TelRecord.ResetTheObject();
TelRecord = (CTeleRecord)readBin.Deserialize(OpFileSt);
PhRecord.SetName = TelRecord.GetName;
PhRecord.SetHomeNumber = TelRecord.GetHomeNumber;
PhRecord.SetMobileNumber = TelRecord.GetMobileNumber;
PhRecord.SetWorkNumber = TelRecord.GetWorkNumber;
PhRecord.SetSpecialNumber = TelRecord.GetSpecialNumber;
PhRecord.SetEmail = TelRecord.GetEmail;
PhRecord.SetNotes = TelRecord.GetNotes;
PhBookContainer.phBookItems.Add(PhRecord);
}
catch (IOException xxx)
{
MessageBox.Show(xxx.Message);
}
catch (ArgumentException tt)
{
MessageBox.Show(tt.Message);
}
//if end of file is reached
catch (SerializationException x)
{
MessageBox.Show(x.Message + x.Source);
break;
}
}
OpFileSt.Close();
PhBookContainer.Save(@"d:\MyPhBook.pbf");
}
}
}
the problem is when i try to read the file ctreated by my old application i receive serialization exception with this message
"Unabel to find assembly 'PhoneBook,Version=1.0.0.0,Culture=neutral,PublicK eyToken=null"
and the source of exceptionis mscorlib.
when i read the same file with my old application(Which is the origin of the file)i have no problem and idon't know what to do to make my
adapter class work.so can somebody help please.

Falcon,
Is this your entire program? If you have other classes in the Phonebook namespace then it would be nice to see them. I would first check that you use the exact same class definition (for the old type of phone book) in your new program as you do in the old. I have had serialization problems, too, and so have others. Also see if you declared a single instance when you needed a variable.
If it wouldn't be too much trouble, could you upload your entire program? If you can't do this, at least upload the class definitions for the old and the new. Thanks.

The binary serializer is looking for an assembly called Photobook.dll. If you 'new' application isn't compiled into a DLL called that then it isn't going to match.
One solution would be, rather than define the old class again in the new application simply add a reference to the old DLL.
