.net 2.0 - Registry Watcher C# -

I am a newbie for WMI and I need to implement in the C # service.

I need an event handler that gets triggered every time, a set of registry values ​​changes. I want behavior similar to class event, but for registry values.

If there is any other technique that I can use to accomplish the same work, then I also appreciate it. My minimum expectation is that this would be the better solution I now have: voting in every 20 seconds and comparing the registry value with the end result.

Please provide example code in your answer. If I can just get an example of seeing a registry value, then it will be fine.

I need a solution in Net 2.0

Thank you.

WMI can sometimes be interesting to work with ... I think I I understand the question, so take a look at the code snippet below and let me know that this is what you are looking for.
