.NET reverse engineering - how to start?

[.netter]

Hi,

I want to crack an .exe file which proff if there is a usb dongle plugged in. It's written in .NET and I used .Net Reflector for getting the source code.

This seems to be the cechk-function.

Do anyone have an idea how to crack the .exe-file. The -net reflectr code is not compileable

PHP Code:

private bool CheckDongleDialog()
        {
         ..........
        } 


I think it's no problem to change the function.

while (1=1) or something like that ...

But how should I start this problem-solving?
