How to delete a registry value in C#

Question

I can get/set registry values using the Microsoft.Win32.Registry class. For example,

Microsoft.Win32.Registry.SetValue(     @"HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run",     "MyApp",      Application.ExecutablePath); 

But I can't delete any value. How do I delete a registry value?

Answer 1

To delete the value set in your question:

string keyName = @"Software\Microsoft\Windows\CurrentVersion\Run"; using (RegistryKey key = Registry.CurrentUser.OpenSubKey(keyName, true)) {     if (key == null)     {         // Key doesn't exist. Do whatever you want to handle         // this case     }     else     {         key.DeleteValue("MyApp");     } } 

Look at the docs for Registry.CurrentUser, RegistryKey.OpenSubKey and RegistryKey.DeleteValue for more info.
