我如何以编程方式检查/如果TUN / TAP驱动程序是用C＃在系统上安装检测？

How do I programmatically check/detect if a TUN/TAP driver is installed on a system in C#?

推荐答案

您可以检查是否有特定的驱动程序被执行的。

You can check if a particular driver is installed by executing a WQL SelectQuery.

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();
        }
    }
}

如果上面的code编译失败，一定要添加引用 System.Management 组件。

If the above code fails to compile, make sure you add a reference to the System.Management assembly.
