c# - 如何查看是否安装了驱动程序？

Question

我正在做一个 VPN 项目。我对 TUN/TAP 有一点疑问。 .

如何在 C# 中以编程方式检查/检测系统上是否安装了 TUN/TAP 驱动程序？

Answer 1

您可以通过执行 WQL SelectQuery 检查是否安装了特定的驱动程序.

using System;
using System.Management;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine("Searching for driver...");

            System.Management.SelectQuery query = new System.Management.SelectQuery("Win32_SystemDriver");
            query.Condition = "Name = 'SomeDriverName'";
            System.Management.ManagementObjectSearcher searcher = new System.Management.ManagementObjectSearcher(query);
            var drivers = searcher.Get();

            if (drivers.Count > 0) Console.WriteLine("Driver exists.");
            else Console.WriteLine("Driver could not be found.");

            Console.ReadLine();
        }
    }
}

如果上述代码无法编译，请确保添加对 System.Management 程序集的引用。
