RegistryKey.Close Method

Closes the key and flushes it to disk if its contents have been modified.

Namespace:  Microsoft.Win32
Assembly:  mscorlib (in mscorlib.dll)

public void Close()

Calling this method on system keys will have no effect, because system keys are never closed.

This method does nothing if you call it on an instance of RegistryKey that is already closed.

This code example is part of a larger example provided for the RegistryKey class.

// Delete or close the new subkey.
Console.Write("\nDelete newly created registry key? (Y/N) ");
if(Char.ToUpper(Convert.ToChar(Console.Read())) == 'Y')
{
    Registry.CurrentUser.DeleteSubKeyTree("Test9999");
    Console.WriteLine("\nRegistry key {0} deleted.", 
        test9999.Name);
}
else
{
    Console.WriteLine("\nRegistry key {0} closed.", 
        test9999.ToString());
    test9999.Close();
}
