Visual C#来创建修改注册信息

核心提示： listBox1.Items.Clear ( ) ; RegistryKey hklm = Registry.LocalMachine ; RegistryKey software = hklm.OpenSubKey ( "HARDWARE", true ) ; Reg

listBox1.Items.Clear ( ) ;
RegistryKey hklm = Registry.LocalMachine ;
RegistryKey software = hklm.OpenSubKey ( "HARDWARE", true ) ;
RegistryKey dddw = software.OpenSubKey ( "aaa" , true ) ;
dddw.SetValue ( "bbb" , "abcd" ) ;　

四．本文中源程序代码( reg.cs )　

reg.cs程序代码如下：
