没有权限写注册表,如何解决.
我是在系统管理员账户下运行调试的.可以读,可是就是不能写注册表.
写注册代码如下:

private void checkautorun_CheckedChanged(object sender, EventArgs e)
{
RegistryKey key = Registry.CurrentUser;
RegistryKey subkey = key.OpenSubKey( "SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Run\\ ");


if (checkautorun.Checked)
{

subkey.SetValue( "autobackup ", System.Diagnostics.Process.GetCurrentProcess().MainModule.FileName);
}
else
{
subkey.DeleteValue( "autobackup ");
}
}

[解决办法]
把
RegistryKey key = Registry.CurrentUser;
RegistryKey subkey = key.OpenSubKey( "SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Run\\ ");
改为
RegistryKey key = Registry.LocalMachine;
RegistryKey subkey = key.OpenSubKey
( "SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Run ",true)

[解决办法]
默认是只读打开的
