Is there a way to detect the network speed and bandwidth usage in C#? Even pointers to open-source components are welcome.

Try using the System.Net.NetworkInformation classes. In particular, System.Net.NetworkInformation.IPv4InterfaceStatistics ought to have some information along the lines of what you're looking for.

Specifically, you can check the bytesReceived property, wait a given interval, and then check the bytesReceived property again to get an idea of how many bytes/second your connection is processing. To get a good number, though, you should try to download a large block of information from a given source, and check then; that way you should be 'maxing' the connection when you do the test, which should give more helpful numbers.
