Iterate through registry sub keys.

[James]

I am trying to read values to the subkeys under HKLM\...\Uninst all.

I get to this point...

RegistryKey Sftw = RegistryKey.Ope nRemoteBaseKey( RegistryHive.Lo calMachine,
name).OpenSubKe y("software").O penSubKey("Micr osoft").OpenSub Key("Windows"). OpenSubKey("Cur rentVersion").O penSubKey("Unin stall");

foreach (string SubKey in Sftw.GetSubKeyN ames())
{

}

and now I want to read some of the values to the subkeys. Nothing I have
tried works. All I have been able to accomplish is reading the name of the
subkey itself.

I feel I am missing something here...

Thanks for any assistance!

James,

You say it doesn't work. Are you sure you have permission to access
those keys? Also, do you get an exception, or it doesn't return the value
that you think you should get?

I'm guessing I just don't know the method to read the subkeys. The only
value I have been able to figure out how to return is the name of the
subkeys... I did try this...

foreach (RegKey SubKey in Sftw.GetSubKeyN ames())
{
Console.WriteLi ne(SubKey.GetVa lue("DisplayNam e").ToString()) ;
}

and caught an error converting string to registrykey.

James,

I see it now. You will have to open each sub key, you can't just cast
it to a registry key. You need to do this:

foreach (string subKeyName in Sftw.GetSubKeyN ames())
{
// Open the key.
using (RegistryKey subKey = Sftw.OpenSubKey (subKeyName))
{
// Write the value.
Console.WriteLi ne(subKey.GetVa lue("DisplayVal ue").ToString() );
}
}

That made the difference... I saw the keyword using in the MSDN examples I
just could not see how to apply it here. Thanks for your help!
