通过注册表开机启动程序

//此方法把启动项加载到注册表中

//获得应用程序路径
string  strAssName = Application.StartupPath +  @"\"  + Application.ProductName +  @".exe" ;
//获得应用程序名
string  ShortFileName = Application.ProductName;

RegistryKey rgkRun = Registry.LocalMachine.OpenSubKey( "SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Run" ,  true );
if  (rgkRun ==  null )
{
    rgkRun = Registry.LocalMachine.CreateSubKey( "SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Run" );
}
rgkRun.SetValue(ShortFileName, strAssName);


//此删除注册表中启动项

//获得应用程序名
string  ShortFileName = Application.ProductName;

RegistryKey rgkRun = Registry.LocalMachine.OpenSubKey( "SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Run" ,  true );
if  (rgkRun ==  null )
{
    rgkRun = Registry.LocalMachine.CreateSubKey( "SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Run" );
}
rgkRun.DeleteValue(ShortFileName,  false );
