Thank you so much Dave.
I got my answer somehow, as soon as I post this thread.
I was thinking maybe the number of packets are too much. But as you said, It was a problem in my code.
Thank you again.

ReadAllBytes from both files and loop through them. What's the problem?

Your question is not clear; how does system information relate to security here?

Security is a broad subject, and there's not a "code to include" or library that you can hookup and say "I'm secure".

Just as your house, when you install a large lock on the door, you feel safer - but hire an expert on the subject and he'll point out the ladder in the backyard, the unlocked windows, and the spare key under the second rock next to your front door.

What is it that you need to secure? A webapp, data, a server, sourcecode, passwords, a physical room with limited access?

Although Microsoft by default give you security like try one thing in Microsoft Visual Studio there exist venerability like XSS(Cross Site Scripting), Sql Injection, http request attack, Directory Listening etc but if you are using older version then you have to secure it by code tricks but in next version Microsoft have been solved this venerability so take regular updates to your visual studio you don't need to worry regarding your application, Although you wan't more security then you can use HTTPS that can be configure by WCF but for that you have to purchase ssl certificate it is mostly use by gmail pages.

Now for that try one thing Create new web application

Visual Studio > New > Website > C# web apllication > Take new Textbox and command button

Now run this project and write

"Alert("Hi");"

Now click on Submit button

It will give you an error like that XSS or CSS(Cross Site Scripting) so now you are secure. Not to worry regarding that just use latest things avoide to use old versions automatically secure.

Basically all wrong.

Software does not and never will be able to provide complete protection.
Technology certainly doesn't.

As an example of that, you store your credit card numbers on your computer and you believe your application is secure. So I just walk into your office and walk out the door with your computer.

Even if you use normal encryption idioms the box I walked out with will still have everything I need to retrieve them in an unencrypted form.

Then you don't know how to ask question dear because you should ask like that how to secure webpage using https encrption i.e. ssl certification with 128bit encryption . You know anything about hacking you have every crack any security have you uploaded any shells, rooted any server, done any type of hacking or something then based on what you can doing so see man in security your mind plays because i know security codding i make my own codding see suppose your website have something another venerability like DNN then there is no meaning for any encryption for that your website should be secured.

For Encrption see one video tutorial

I don't need to ask how to do that. I do however know that if you think doing just that makes your business secure then you are wrong.

Not sure what that means except you seem to be agreeing with me in that technology does not make a business secure.
