Reading a registry key in C#

Question

I have developed an application and installed it on a client computer. In my application I need to get its installation path. My application has a registry entry at:

HKEY_LOCAL_MACHINE\SOFTWARE\MyApplication\[AppPath] 

How can I read AppPath using C#?

Answer 1

You're looking for the cunningly named Registry.GetValue method.

Answer 2

string InstallPath = (string)Registry.GetValue(@"HKEY_LOCAL_MACHINE\SOFTWARE\MyApplication\AppPath", "Installed", null);     if (InstallPath != null) {     // Do stuff } 

That code should get your value. You'll need to be

using Microsoft.Win32; 

for that to work though.
