如何禁用特定的usb端口com2 c＃64位

Question

I have tried to disable com port by using

Microsoft.Win32.Registry.SetValue(
    @"HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\USBSTOR",
    "Start",
    4,
    Microsoft.Win32.RegistryValueKind.DWord
); 

//enable USB storage...
Microsoft.Win32.Registry.SetValue(
    @"HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\USBSTOR",
    "Start",
    3,
    Microsoft.Win32.RegistryValueKind.DWord
);

but doesn't work in 64 bit pc.

Is there any other solution to disable com port in 64 bit?

Eugh. Don't do this. Use SetupDiSetClassInstallParams or WMI + devcon or really anything other than editing the registry!

_{But to use registry you need to specify RegistryView.Registry64 , or clear the Prefer 32 bit flag in the project properties}
