Win32 API 允许以编程方式禁用和启用设备。但是,并非所有设备都支持此功能。尝试使用 SetupDi API 禁用触摸板时,可能无法实现,因为默认鼠标驱动程序通常不支持此操作。
要验证设备是否可禁用,请检查禁用选项是否可用装置经理。如果存在,则可以使用以下代码:
public static void EnableMouse(bool enable) { // Example mouse GUID: {4d36e96f-e325-11ce-bfc1-08002be10318} Guid mouseGuid = new Guid("{4d36e96f-e325-11ce-bfc1-08002be10318}"); // Get the instance path from Device Manager string instancePath = @"ACPI\PNP0F03&3688D3F&0"; DeviceHelper.SetDeviceEnabled(mouseGuid, instancePath, enable); } ```` Here's the supporting library:
using System;
using System.Text;
using System.Collections.Generic;
using DisableDevice;
使用 System.Runtime.InteropServices;
使用 System.ComponentModel;
使用Microsoft.Win32.SafeHandles;
使用 System.Security;
使用 System.Runtime.ConstrainedExecution;
使用 System.Management;
命名空间 DisableDevice
