Yes you are right. After commenting out some code the sockets weren't disconnecting but I still don't get it as I understood that too many processes in the application are causing this but how do they lead sockets(async) to disconnect? Because this has never happened before and I'm curious to know what is it exactly happening causing this issue.

Are these some mistakes that are causing the socket to disconnect?

I tried using Encoding.UTF8.GetBytes() and Encoding.UTF8.GetString().

I tried
byte[] dataRead = File.ReadAllBytes(op.FileName);
byte[] data = Encoding.UTF8.GetBytes(Encoding.UTF8.GetString(dataRead));
to get the file into UTF8 and after writing it returns with corrupt file with invalid size
File.WriteAllBytes(filenameandpath, data);

So should I change my whole architecture of the application to UTF8Encoding? Because how my application works is client request server data by sending a string as request type|request data|ip address and server replies with request type|requested data|actual data so this is all happening in ASCII. So are you suggesting me to do everything in UTF8Encoding, UnicodeEncoding, or UTF32Encoding?

Second, I'm using byte[] dataToDownload = Encoding.ASCII.GetBytes(dataString); and later using it in File.WriteAllBytes() which is not working.

Hello Pete, thanks for your reply. I have noted your points and would definitely implement them in my program and also in my habits.

Sure I will try to implement it.

Will the sending of whole info into single message be a mess because server wouldn't know how much to receive?
and regarding the network transfer I'm renting a server i.e. Amazon EC2 or Azure Webjobs.

Yes, thanks for the information but this is for personal and limited use so file size is not large but still would you let me know any tutorials where I can get knowledge about how can I recognize change on the screen?
I'm new to this and very much eager to learn.

Oh now I got it. So I should receive data from client and send an acknowledgement back to client and client should send the data and wait for correct acknowledgement from server to send next data?

To make things clear. The client is the sender here and the server is the receiver. FYI I'm not assuming here I've demonstrated and replied to you. In my case this is what happening

Client sends the size(logged and checked)
Server receives it
Client sends the data(logged and checked)
Server receives it and checks for the size
Client sends the size(logged and checked)
Server receives it but incorrectly
Client sends the data(logged and checked)
Server receives it and checks for the size

As I've said I tried to check both the sides the sender and receiver(with catch block to log the errors) and client is sending data correctly as I have logged the data sent and error message too. Client is not throwing any error and data sent is also correct.
With server the case is that server receives the size at first which itself is incorrect and if you're saying that previous data might be out of sync so that has not happened because previous data was successfully sent and received. So taking the incorrect value as size the server declares a byte[incorrect size] to receive the data and as size is incorrect the byte[] throws an error.

The exception is ok but my question is regarding the value that is causing the compiler to throw error. Exception is thrown on overflow of byte[] but the value i.e. data size is incorrect comparing to what is sent and that size is throwing exception. I don't know what is happening to the data size when received on server.

Server is throwing "Exception of type 'System.OutOfMemoryException' was thrown." on byte[] data = new byte[size]; as the value I got is "1734438217".

I said "Also I tried logging exceptions as you said but it seems client is not throwing any exceptions"

Actually the data is sent correctly from the client as you can see in the results on sent byte[] value from client. Also I tried logging exceptions as you said but it seems client is not throwing any exceptions and working correctly. I think the problem is with the server as it seems it's messing with the byte[] of datasize.

Thanks for the answer. I will check this.

How can I achieve sending image file name and image both in the same byte[]?

The code is my previous code that works but I using that same working byte[] to convert to string and again to byte[] won't work.

Thanks for your solution but I tried using binary formatter method before and it's very slow process as it gives me 3fps on my local server and I can't imagine how slow it would process if I used a hosted server on the internet.

but how can I work with while(true) in both write and read? As if I'm reading the chunked data received in a while loop get total number of bytes received but write keeps writing the data in the networkstream and this causes the chunk reading to go in infinite loop.

I have searched it for weeks but still no luck. What making me mad is there are some other applications have that functionality but I can't find any solution till date.

This is not what I want. I want to fetch skype conversation from skype installed on the system to my c# application.
