[英]C# Detect USB Mouse (Logitech Mouse)
我在该网站上关注了其他一些有关在C#中检测鼠标状态的问题。 我的第一个理解是鼠标检测并不简单。 没有这样做的本机库,这对我来说似乎很奇怪。 但是我希望编写一个轻巧的C#控制台应用程序,最终将其转换为Windows服务,以检测是否存在我的USB Logitech鼠标。
当Windows 10中存在鼠标并且我遵循的所有指南都不适合我时,我一直在尝试禁用触摸板的方法,因此,我决定为其构建自己的小程序。 我不希望使用nuget库来实现此目的,我想在这里提供一些简单的功能。
我拥有当前的代码块,但我只看到过我认为是我的触摸板的Elan设备。
static async Task StartListenForMouseChangeAsync()
{
await Task.Factory.StartNew(()=> {
do
{
var mouse = new ManagementObjectSearcher("winmgmts:\\.\\root\\CIMV2");
mouse.Query = new ObjectQuery("SELECT * FROM Win32_PointingDevice");
var data = mouse.Get();
foreach (var obj in data)
{
foreach (var item in obj.Properties)
{
Console.WriteLine($"{item.Name} -- {item.Value}");
}
}
Thread.Sleep(5000);
Console.Clear();
} while (true);
}, TaskCreationOptions.LongRunning);
}
样本输出:

将代码更改为此解决了我的问题
