如何访问使用c＃lang安装的驱动程序列表。 [英] how to access the list of drivers installed using c# lang.

问题描述

我试过这个并没有给出驱动程序列表。我试图在列表或数组中获取驱动程序列表。

I have tried this and its not giving the list of drivers. I am trying to get the driver list in a list or array.

ManagementObjectSearcher searcher = new ManagementObjectSearcher("SELECT * FROM Win32_PnPSignedDriver");

                foreach (ManagementObject obj in searcher.Get())

                {
                    string s;
                    s = string.IsNullOrEmpty(obj.GetPropertyValue("DeviceName").ToString()) ? string.Empty : obj.GetPropertyValue("DeviceName").ToString();
                    Debug.Print(s);
                }

请为我推荐一些不同的方法。



提前谢谢

推荐答案

您的代码中存在一个错误，调试器可能会找到该错误。试试我修改后的版本：

There is a bug in your code, which the debugger would have found for you. Try my modified version which works:

foreach (ManagementObject obj in searcher.Get())
{
    if (obj.GetPropertyValue("DeviceName") == null)
        continue;
    string s = obj.GetPropertyValue("DeviceName").ToString();
    if (!string.IsNullOrEmpty(s))
        Debug.Print(s);
}
