c# - NetworkStream.Read did not get all the bytes after a null byte/s -

I am creating an application that can remotely control a device such as camera (Scopia XT5000 - Radvision) Will happen. I need to send an initialization command to the device so that I can send AT commands which will control the device.

Once I send the initial order, the server should answer it:
In the string

? ? \ 0 \ 0 \ 0 AT [& lt; IP400C9XT5000-03.01.00.0028 \ r ?? \ 0 \ 0 \ 0 ok \ r \ /

Bytes

170 170 0 32 65 84 91 60 73 80 52 48 48 67 57 88 84 53 48 48 48 45 48 51 46 48 49 46 48 48 46 48 48 50 56 13 170 170 0 0 3 79 75 13

I have to debug Tried and received those values ​​when I broke here

serverStream.Read (instream, 0, inStream.Length);

But every time I run programs without debugging or braking, it will give me different strings and bytes. Just like in the string

? \ 0 \ 0 \ 0 \ 0 \ 0 \ 0 \ 0 \ 0 \ 0 \ 0 \ 0 \ 0 \ 0 \ 0 \ 0 \ 0 \ 0 \ 0 \ 0 \ 0 \ 0

Bytes

170 170 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0

What could be the problem? Is it:
- Tap bytes?
- Carriage return? "\ R"?
- Multiple lines?

 read  read  Returns the number of bytes, you have a 10025-byte buffer, but it is not complete after  read . You want to be able to read all the bytes as long as you want.  
 This works when you debug because, due to the extra time spent, the result of the network stream is fully received, so when  < / P> 
 references:    is read, all data is available And is put into buffer
