This article mainly explains the "case analysis of C # operation registry". The content of the explanation is simple and clear, and it is easy to learn and understand. Please follow the editor's train of thought. Let's study and learn "C # operation registry case analysis".

In the following example, note:

Build function: CreateSubKey ()

Create subkey function: SetValue ()

Practice of class Program / / C # operating registry instance {static string Generateguid () / / function {return System.Guid.NewGuid (). ToString () to establish guid values;} static void Main (string [] args) {RegistryKey pregkey; string preName; / / pregkey = Registry.CurrentUser.OpenSubKey ("Control Panel\\ Desktop\\ WindowMetrics", true); pregkey = Registry.LocalMachine.OpenSubKey ("SOFTWARE\ Microsoft\\ Internet Explorer\ Extensions", true) / / retrieve subkey if (pregkey = = null) {Console.WriteLine ("the key does not exist");} / / practice else {preName = Generateguid (); Console.WriteLine (preName); Console.WriteLine ("find the key"); preName = "{" + preName + "}"; / / pregkey.SetValue ("MinAnimate", "1"); pregkey.CreateSubKey (preName) / / create a subkey pregkey = Registry.LocalMachine.OpenSubKey ("SOFTWARE\\ Microsoft\\ Internet Explorer\\ Extensions\\" + preName, true); / / pregkey.SetValue ("bbbbb", "0"); / / create a subkey, if there is one, set the value. Pregkey.SetValue ("ButtonText", "add"); / the text pregkey.SetValue ("CLSID", "{1FBA04EE-3024-11d2-8F1F-0000F87ABD16}") displayed when the mouse is over the bar; / / CLSID fixed pregkey.SetValue ("Default Visible", "yes"); / / default view, C # operating registry instance practice pregkey.SetValue ("Exec", "D:/IEbar/IEpinout.exe") / / the associated exe file pregkey.SetValue ("HotIcon", "D:/IEbar/Icon2.ico"); / / the pattern pregkey.SetValue ("Icon", "D:/IEbar/Icon1.ico") displayed when the mouse is over bar; / / the pattern displayed when the mouse is not over bar / / pregkey.SetValue ("MenuStatusBar", "Yang"); / / pregkey.SetValue ("MenuText", "I am Yang!") ;} / / C # operating registry instance practices pregkey.Close ();}}

This example has been debugged under vs2005,xp system.

Generate the exe file, run it directly, and then open ie to see the effect on the toolbar.

Note: there must be two files "D:/IEbar/Icon2.ico" and "D:/IEbar/Icon1.ico", otherwise the effect will not be seen on ie.
