C# windows client get registry value

I have a c# windows client app packaged using ClickOnce. Us开发者_C百科ing c# how can I programmatically get the registry entry for that application? As I am wanting to write a registry entry for a child app NEAR the same location

AFAIK, the only registry key ClickOnce might create is the key related to displaying the application in the system's Add/Remove Programs control panel for uninstall purposes. I doubt this is what you want. It is not appropriate to write configuration settings there. Thus, there is no existing "registry entry for that application" for you to get.

If you want to store settings, there is a whole "application settings" infrastructure for this. It is file-based, not registry-based. It play well with ClickOnce.

You can, of course, create a registry entry yourself in any part of the registry where the user has suitable access. The class for doing this is Microsoft.Win32.Registry: http://msdn.microsoft.com/en-us/library/microsoft.win32.registry.aspx

A good choice of registry location would be HKEY_CURRENT_USER\Software\YourCompanyName\YourProductName.

U can define and get a registry key like this.

        // Define a key
        Microsoft.Win32.RegistryKey key;
        key = Microsoft.Win32.Registry.CurrentUser.CreateSubKey("AppName");
        key.SetValue("AppName", "Cracker");
        key.Close();


        // Retrieving data
        object keyData = Microsoft.Win32.Registry.CurrentUser.GetValue("AppName");
