如何找到设备所属类的GUID

在这里插入图片描述

/// <summary>
/// HID
/// </summary>
private static readonly string HIDDevice = "{745a17a0-74d3-11d0-b6fe-00a0c90f57da}";

/// </summary>
private static readonly string Keyboard = "{4d36e96b-e325-11ce-bfc1-08002be10318}";

/// </summary>
private static readonly string Mouse = "{4d36e96f-e325-11ce-bfc1-08002be10318}";
/// <summary>
/// USB
/// </summary>
private static readonly string USB = "{36fc9e60-c465-11cf-8056-444553540000}";

禁用方法

public static void DisableDevice(string deviceClassGuid)
{
    IntPtr info = IntPtr.Zero;
    Guid NullGuid = Guid.Empty;
    try
    {
        info = SetupDiGetClassDevsW(ref NullGuid, null, IntPtr.Zero, DIGCF.ALLCLASSES|DIGCF.PROFILE);
        SP_DEVINFO_DATA devdata = new SP_DEVINFO_DATA();
        devdata.cbSize = (UInt32)Marshal.SizeOf(devdata);
        ///遍历设备
        for (uint i = 0; SetupDiEnumDeviceInfo(info, i, out devdata); i++)
        {
            if (devdata.ClassGuid == new Guid(deviceClassGuid))
            {
                SP_CLASSINSTALL_HEADER header = new SP_CLASSINSTALL_HEADER();
                header.cbSize = (UInt32)Marshal.SizeOf(header);
                header.InstallFunction = DIF.PROPERTYCHANGE;
                SP_PROPCHANGE_PARAMS propchangeparams = new SP_PROPCHANGE_PARAMS
                {
                    ClassInstallHeader = header,
                    StateChange = DICS.DISABLE,
                    Scope = DICS_FLAG.GLOBAL,
                    HwProfile = 0
                };
                SetupDiSetClassInstallParams(info, ref devdata, ref propchangeparams, (UInt32)Marshal.SizeOf(propchangeparams));
                SetupDiChangeState(info, ref devdata);
            }
        }
    }
    catch (Exception ex)
    {
        throw new Exception(string.Format("ChangeMouseState failed,the reason is {0}", ex.Message));
    }
    finally
    {
        if (info != IntPtr.Zero)
            SetupDiDestroyDeviceInfoList(info);
    }
}

启用方法

public static void EnableDevice(string deviceClassGuid)

        devdata.cbSize = (UInt32)Marshal.SizeOf(devdata);
        ///遍历设备
        for (uint i = 0; SetupDiEnumDeviceInfo(info, i, out devdata); i++)
        {
            if (devdata.ClassGuid == new Guid(deviceClassGuid))
            {
                SP_CLASSINSTALL_HEADER header = new SP_CLASSINSTALL_HEADER();
                header.cbSize = (UInt32)Marshal.SizeOf(header);
                header.InstallFunction = DIF.PROPERTYCHANGE;
                SP_PROPCHANGE_PARAMS propchangeparams = new SP_PROPCHANGE_PARAMS
                {
                    ClassInstallHeader = header,
                    StateChange = DICS.ENABLE,
                    Scope = DICS_FLAG.GLOBAL,
                    HwProfile = 0
                };
                SetupDiSetClassInstallParams(info, ref devdata, ref propchangeparams, (UInt32)Marshal.SizeOf(propchangeparams));
                SetupDiChangeState(info, ref devdata);
            }
        }
    }
    catch (Exception ex)
    {
        throw new Exception(string.Format("ChangeMouseState failed,the reason is {0}", ex.Message));
    }
    finally
    {
        if (info != IntPtr.Zero)
            SetupDiDestroyDeviceInfoList(info);
    }
}
