C＃-如何以编程方式关闭Windows 8 10的WiFi

Question

我正在编写一个禁用WiFi的应用程序。 这不能通过使用WMI禁用网络适配器或调用netsh等来完成。对于Windows 10，我可以运行以下代码。 对于Windows 8，该如何做？

using Windows.Devices.Radios;

public async void TurnWifiOff()
{
    await Radio.RequestAccessAsync();
    var radios = await Radio.GetRadiosAsync();

    foreach (var radio in radios)
    {
        if (radio.Kind == RadioKind.WiFi)
        {
            await radio.SetStateAsync(RadioState.Off);
        }
    }
}

Mike Petrichenko，谢谢您的提示。 我找到了基于CodePlex提供的“ wlanapi.dll”的解决方案： https : //archive.codeplex.com/? p=managedwifi在将两个文件“ Interop.cs”和“ WlanApi.cs”添加到项目后，以下代码完成了工作

using NativeWifi;
using System.Runtime.InteropServices;

{

    WlanClient client = new WlanClient();
    foreach (WlanClient.WlanInterface wlanIface in client.Interfaces)
    {
        IntPtr radioStatePtr = new IntPtr(0L);
        try
        {
            Wlan.WlanPhyRadioState radioState = new Wlan.WlanPhyRadioState();
            radioState.dwPhyIndex = 0;
            radioState.dot11HardwareRadioState = Wlan.Dot11RadioState.On;
            radioState.dot11SoftwareRadioState = Wlan.Dot11RadioState.Off; //In this place we set WiFi to be enabled or disabled

            radioStatePtr = Marshal.AllocHGlobal(Marshal.SizeOf(radioState));
            Marshal.StructureToPtr(radioState, radioStatePtr, false);

            Wlan.ThrowIfError(
                Wlan.WlanSetInterface(
                            client.clientHandle,
                            wlanIface.InterfaceGuid,
                            Wlan.WlanIntfOpcode.RadioState,
                            (uint)Marshal.SizeOf(typeof(Wlan.WlanPhyRadioState)),
                            radioStatePtr,
                            IntPtr.Zero));
        }
        finally
        {
            if (radioStatePtr.ToInt64() != 0)
                Marshal.FreeHGlobal(radioStatePtr);
        }
    }
}
