Solution 1

For all applications or just your own that is doing some transferring of data??

For all applications, no, there is no setting to limit this. Theere are two ways of doing this. The first would be to put a proxy/firewall server between the client machine and its destination server, which has the capability of throttling bandwidth.

The second would be to write a driver that is inserted into the network stack that does the same job. This cannot be easily written in C# and, frankly, you don't want the full weight of the .NET Framework added to the kernel anyway. You would normally use C/C++ for this job.

For only your application, you would need to write your sending code to pace itself, only sending data in small bursts once in a while.

Frankly, now-a-days, I don't see the point in limiting bandwidth.

I already told you what needs to be done.

There is nothing more. I already told you what to do. If you can't write a driver, which is a VERY advanced thing to take on, then you have no choice but to buy and off-the-shelf proxy server product. You'll, of course, have to learn to administer that too.

The second method is better?
I'm a newbie.
Where can I get help from.
Thanks for the reply

If you're a newbie, there's no way you're going to be writing a driver. Like I said, it's a VERY advanced topic in Windows development. You better have a very good knowledge of the Windows network stack, Windows internals, and how to do kernel-mode debugging. There is no one tutorial that will take you through the entire process of developming such a driver. You can find pieces of this process, but you've got a ton of research to do to even attempt this. Good luck. You can start with:
