Getting binary serialization / deserialization progress

Question

Hello !

I would like to handle the progress of binary serialization / deserialization of files to show a "loading" progress bar to the user but I cant't find a solution to do that.

Is there a good solution please ?

Thanks

Steeve

Answer 1

I dont think you can see what the serialization code do behind the scene at runtime but try to run your serialization and deserialization method with progress bar or backgroundworker. With backgroundworker, the user can see the progress status.

Thanks for your reply but I think you didn't understood what I wanted.

Imagine a big file (about 100MB) that would be deserialized. I would like to display the progress of the deserialization of this only file. So if I make what you said, I would only have a two states progressbar :

- State to 0% before deserialization

- State to 100% when the file is deserialized

But no intermediate states from 1% to 99%.

Or perhaps, what you told me has a mechanism to catch the serialization/deserialization progress ? If so, can you please give me an example please ?

Thanks

Hi insomniak49,

As we know, BinaryFormatter does not expose any events we can hook to listen for progress notifications. But if we can figure out how much of the stream the BinaryFormatter has read, we can create a good approximation for how much of the deserialization process has been completed.

I have found an article regards deserialization progress that you may want to read. http://msdn.microsoft.com/en-us/magazine/cc163515.aspx

I hope this information is helpful.

 

Best Regards,

Hi Kee,

 

Thanks for your answer, this article is really great. I've contacted the author to see if he had a solution for serialization because his article only talks about deserialization but he said that there is no real solution to approximate the size of the serialized tree object.

Why will you serialize and deserialize a 100MB file, is it than not better to use one of the compression methods?

It was only for the example, but thanks for your information, I didn't knew I could do that :)
