public static string GetEnvironmentVariable (string variable, environmentvariabletarget target);
Summary: Retrieves all environment variable names and their values from the current process.
public static IDictionary getenvironmentvariables ();
Summary: Retrieves all environment variable names and their values from the current process or from the Windows operating system registry key for the current user or local computer.
