How do I check whether a user is allowed to read / write a particular registry key?

Question

Does anybody know how I can programmatically check (using C#) whether my program will be able to read / write a particular registry key (specifically: \"SOFTWARE\\Microsoft\

Answer 1

Simplest option is to try and open the key with write access and see if you get it. Remember to close the key afterwards.

bool fWriteAccess;
try {
    Registry.LocalMachine.OpenSubKey("SOFTWARE\Microsoft\Windows\CurrentVersion\Run", True).Close();
    fWriteAccess = True;
} catch (SecurityException) {
    fWriteAccess = False;
}
