RegistryKey
Synopsis
The RegistryKey class contains
the core functionality for
reading and writing to the Windows registry. Each
RegistryKey object represents an individual key in
the registry. You can use the properties of this class to find out
how many values this key contains (ValueCount),
how many subkeys (SubKeyCount) there are, and the
fully qualified key name (Name).
To open a subkey for modification, use the overloaded version of the
OpenSubKey( ) method—which allows you to
specify the writable parameter—and set it to
true. You can open subkeys that are several levels
deep by separating keys with a backslash (\). In C#, the backslash
must be escaped, as in
mykey.OpenKey("Software\\Microsoft").
You can also use methods such as CreateSubKey( )
and DeleteSubKey( ). In the registry, keys are
logical groupings, and values are the entries used to store the
actual data. You can use the GetValue( ),
SetValue( ), and DeleteValue( )
methods to manipulate a named value in the current key.
Changes to the registry are propagated across the system
automatically and are flushed to disk automatically by the system.
You should never need to use methods such as Flush( ), unless you require absolute certainty that a registry
change has been written to disk. The OpenRemoteBaseKey( ) method opens the registry on a remote computer, provided
both machines are running the remote registry service and have remote
administration enabled.
