推荐答案

我需要使用c＃禁用计算机的USB端口。 />


以下是适用于32位窗口但不能正常工作的解决方案...我需要一个相同的功能，它可以为64位做同样的事情... 。



//禁用USB存储...

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



//启用USB存储...

Micr osoft.Win32.Registry.SetValue（@HKEY_LOCAL_MACHINE \SYSTEM \ CurrentControlSet \ Services \ USBSTOR，Start，3，Microsoft.Win32.RegistryValueKind.DWord）;



i可以读取Windows 64位上的值，但无法写入值....

RegistryKey registryKey = RegistryKey.OpenBaseKey（Microsoft.Win32.RegistryHive.LocalMachine，RegistryView.Registry64 ）;



Console.WriteLine（registryKey+ registryKey）;





registryKey = registryKey.OpenSubKey（@SYSTEM\CurrentControlSet\Services\USBSTOR）;

Object val = registryKey.GetValue（Start）;

Console.WriteLine（val是：+ val）;

这里我得到当前设置的val ...

但是当我尝试在写模式下打开...

registryKey = registryKey.OpenSubKey（@SYSTEM\CurrentControlSet \ Services \ USBSTOR，true）;

并尝试设置值为4到di sable它无法工作......

registryKey.SetValue（开始，4）;

I need to disable USB port of the computer using c# ..

below is the solution which is working for 32 bit windows but not working 64 bit ... I need a same function which can do the same thing for 64 bit ....

//disable USB storage...
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);

i can read the value on windows 64 bit but can not write the value....
RegistryKey registryKey = RegistryKey.OpenBaseKey(Microsoft.Win32.RegistryHive.LocalMachine, RegistryView.Registry64);

Console.WriteLine("registryKey" + registryKey);


registryKey = registryKey.OpenSubKey(@"SYSTEM\CurrentControlSet\Services\USBSTOR");
Object val = registryKey.GetValue("Start");
Console.WriteLine("The val is:" + val);
here i am getting the current val which is set ...
but when i try to open in write mode...
registryKey = registryKey.OpenSubKey(@"SYSTEM\CurrentControlSet\Services\USBSTOR", true);
and try to set a value 4 to disable it cant work...
registryKey.SetValue("Start", 4);
