I don't know about .NET, but the Win32 functions are all listed here: Console Functions (MSDN).

You will need to enable mouse input with SetConsoleMode.
You can read it using ReadConsoleInput.

Use GetStdHandle to get a windows handle for the console input.
Use GetNumberOfConsoleInputEvents to poll for any console input, or use the console input handle with one of the wait functions.

Hope this helps.

[EDIT] Alas, AD, the cursor info is for the little blinking square or underline in the output console display.
