Question
Is there a way to detect the network speed and bandwidth usage in C#? Even pointers to open-source components are welcome.
Solution
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.
OTHER TIPS
You should be able to calculate everything you need from the IPGlobalStatistics class.
