win10 系统，c#如何禁用和启用网卡

我需要将网卡禁用，然后再启用，网上搜了很多代码，都只能是启用或者禁用，想要用反过来就必须重启程序，但是win7可以自由禁用和启用，win10要么禁用要么启用，代码如下：
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
const string discVerb = "禁用(&B)";
const string connVerb = "启用(&A)";
public void Start(string netName,string action)
{
Shell sh = new Shell32.Shell();

Folder folder;
folder = sh.NameSpace(49);
foreach (FolderItem myItem in folder.Items())
{
if (myItem.Name == netName)
{

//禁用//启用网络
foreach (FolderItemVerb Fib in myItem.Verbs())
{
if (Fib.Name == action)
{
Fib.DoIt();
break;
}
}
}
}
}

private void buttonStart_Click(object sender, EventArgs e)
{
Start(textBox1 .Text , connVerb);
}
private void buttonStop_Click(object sender, EventArgs e)
{
Start(textBox1.Text, discVerb);
}
}

    麻烦看一下问题在哪里，或者有其它办法实现这个功能，谢谢

有调试过，就是右键的状态没有刷新，比如说程序开启的时候网卡是启用状态，执行FolderItemVerb Fib in myItem.Verbs这段的时候，里面就有禁用的选项，就可以禁用网卡，这个时候网卡处于禁用状态，当我需要启用的时候，执行这段代码，里面还是之前的状态，有禁用没有启用选项，win7就不会有这个情况。

试试看 wmi 的方法

楼主的代码 如果不重启程序 切换启用和禁用 是什么效果？有报错吗？有的话 贴出来看看
或者调试跟踪一下 看看有没有异常
