C#. How to operate registry RegistryKey in net

Look at the help of RegistryKey, this thing is not complicated, such as:

1, add key plus value

01.string appName = "Poweroffontime";
02.//gets the assembly that executes the method and gets the file path of the assembly (the directory where the assembly is located by the file path)   
03.string Thisexecutablepath = System.Reflection.Assembly.GetExecutingAssembly (). Location;  
This path in the 04.//software\\microsoft\\windows\\currentversion\\run registry is the boot-initiated path   
05.microsoft.win32.registrykey Rkey = +  
.    Microsoft.Win32.Registry.LocalMachine.CreateSubKey  
.    ("Software\\microsoft\\windows\\currentversion\\run");  
08.rkey.setvalue (AppName, thisexecutablepath);   
09.rkey.close ();  

The effect is as follows:

2, read the key value

Microsoft.Win32.RegistryKey Rkey =  
                   Microsoft.Win32.Registry.LocalMachine.CreateSubKey  
                   ("software\\ Microsoft\\windows\\currentversion\\run ");
String  Key = Rkey.getvalue ("Poweroffontime"). ToString ();

The effect is as follows:

3. Create a new file in the registry and add a key value under the folder

String appName = "Poweroffontime";  
Gets the assembly that executes the method, and gets the file path of the assembly (the directory where the assembly is located by the file path)  
string thisexecutablepath = System.Reflection.Assembly.GetExecutingAssembly (). Location;  
RegistryKey src = Registry.LocalMachine.OpenSubKey ("SOFTWARE", true). OpenSubKey ("Microsoft", true). OpenSubKey ("Windows", true). OpenSubKey ("CurrentVersion", true). OpenSubKey ("Run", true);  
Write to the registry key (that is, the folder)  
RegistryKey red = src. CreateSubKey ("Poweroffontime");  
Write the value red in this folder  
. SetValue (AppName, Thisexecutablepath);

The effect is as follows:

4, delete key

RegistryKey src = Registry.LocalMachine.OpenSubKey ("SOFTWARE", true). OpenSubKey ("Microsoft", true). OpenSubKey ("Windows", true). OpenSubKey ("CurrentVersion", true). OpenSubKey ("Run", true);

Src. DeleteSubKey ("Poweroffontime");

The effect is as follows:

Note

Modify the registry, especially the boot automatically startup registry The biggest advantage is that when you write small programs, you can automatically perform every day, such as: you want to write a time when the automatic shutdown of the small program ...
