Sending Through Network with Binary Serialization

[music7611]

I have this program that sends an object to a differant program on a differant computer. It uses BinaryFormatter. That program has an exact copy of that class. Is there any way to do this without using DLLs or anything? Edited March 22, 2004 by music7611

Can you send me more details?

 

I can manage to produce a binary serialization of my class , storing it on a folder and then loading it from other application instance. I am not using any DLL, you can serialize using a normal APP or a WEB app as well.

 

Indeed I have four engines running as a service that serialize the data and can share information.

OK. So I have 2 Entirely Differant Applications. They each have the same class inside of them. They are each on 2 differant computers. The sender program is called ATM. Whenever I send the data, I get an error that says this...

 

System.IO.FileNotFoundException: File or assembly name ATM, or one of its dependencies, was not found.

Can you help me?

You need to derive a class from SerializationBinder and then set the Binder property on your BinaryFormatter.

 

e.g.

internal class ConvertingBinder : SerializationBinder

{

 

public override Type BindToType(string assemblyName, string typeName)

{

if ( assemblyName.StartsWith("MyOtherProgram") )

{

return System.Type.GetType( typeName ); // Get it from this assembly

}

else

{

return System.Type.GetType( typeName + "," + assemblyName );

}

 

}

}

Thanks a lot

Thanks a lot for the code! It will help a whole ton!!! I'm so excited and I can't wait to try it out.
