C# How do i iterate through the registry?

Question

Hey, how can iterate through the registry using c#? I wish to create a structure for representing attributes of each key.

I think what you need is GetSubKeyNames() as in this example.

private void GetSubKeys(RegistryKey SubKey)
{
    foreach(string sub in SubKey.GetSubKeyNames())
    {
      MessageBox.Show(sub);
      RegistryKey local = Registry.Users;
      local = SubKey.OpenSubKey(sub,true);
      GetSubKeys(local); // By recalling itself it makes sure it get all the subkey names
    }
}

//This is how we call the recursive function GetSubKeys
RegistryKey OurKey = Registry.Users;
OurKey = OurKey.OpenSubKey(@".DEFAULT\test",true);
GetSubKeys(OurKey);
