Having trouble loading serialized object file into another program

[Zarz]

Hello,

I have been trying to save a object to a file then read the object back into
another program. I have a map maker program and a map reader program and
for some reason after I save the map data to file in the maker it will not read
it in the map reader program. I can read and load the file fine in the
mapmaker program but i get this error that seems to indicate that it is looking
for the original program that made the file as part of the deserializing of the
object from the file. Mapmaker is the original program that produced the data
file.

An unhandled exception of type 'System.Runtime.Serialization.SerializationExcepti on' occurred in system.runtime.serialization.formatters.soap.dll

Additional information: Parse Error, no assembly associated with Xml key a1:http://schemas.microsoft.com/clr/nsa...r/Mapmaker,%
20Version%3D1.0.3022.24556%2C%20Culture%3Dneutral% 2C%20PublicKeyToken%3Dnull Map

Here is the code segment I have been using I have tried both soap and binary
formatters and basically get the same error. All this should do is load the file
back into a Map Object.

Dim fs As FileStream
Dim mapin As Map
Dim bf As SoapFormatter = New SoapFormatter


Dim result As DialogResult
Open.InitialDirectory = Application.StartupPath
result = Open.ShowDialog
If result <> DialogResult.Cancel Then
fs = New FileStream(Open.FileName, FileMode.Open)
mapin = CType(bf.Deserialize(fs), Map)
fs.Close()
End If

Here is the Map object I am trying to serialize and read into a seperate
program.

<Serializable()> Public Class Map
Private StartX As Integer
Private StartY As Integer

Private Textures(,) As Image

Public Sub New(ByVal tex(,) As Image)
StartX = 0
StartY = 0
Textures = tex
End Sub

Public Sub New(ByVal x As Integer, ByVal y As Integer, ByVal tex(,) As Image)
StartX = x
StartY = y
Textures = tex
End Sub
End Class

Nothing much just testing some ideas on saving and loading image files.
All the class is is an x and y coordinates for start location and a 2 dimensional
array to hold the Image files to be sent to the drawing routine.

Is reading a serialized object from a file into a seperate program even
possible in vb.net? And if so what steps am I missing Any help would be appreciated.

p.s.
sorry for duplicate post meant to post it here first time

Serialization of "Map" type is assembly specific, defining a "Map" type in both your apps (assemblies) will not create compatible types for serialization. To do that define the "Map" type in a class library and reference this assembly from both apps.

Thanks for your help thats what I ended up doing and it works great
