我可以在Windows Phone 8.1上以编程方式打开和关闭WiFi吗?

如果是这样,如何在C#上打开/关闭wifi?

实际上,我已经在另一个平台上做到了这一点:

<DllImport("coredll.dll")> Public Shared Function DevicePowerNotify(ByVal device As String, ByVal state As CEDEVICE_POWER_STATE, ByVal flags As Integer) As Integer  
End Function  

<DllImport("coredll.dll")> Public Shared Function SetDevicePower( _  
ByVal pvDevice As String, _  
ByVal df As Integer, _  
ByVal ds As CEDEVICE_POWER_STATE) As Integer  
End Function  

Public Shared Sub wifi_power_on()  
    Try  
        DevicePowerNotify("{98C5250D-C29A-4985-AE5F-AFE5367E5006}\cardname", CEDEVICE_POWER_STATE.D0, 1)  
        SetDevicePower("{98C5250D-C29A-4985-AE5F-AFE5367E5006}\cardname", 1, CEDEVICE_POWER_STATE.D0)  
        Application.DoEvents()  
    Catch  
    End Try  

End Sub  

Public Shared Sub wifi_power_off()  
    Try  
        DevicePowerNotify("{98C5250D-C29A-4985-AE5F-AFE5367E5006}\cardname", CEDEVICE_POWER_STATE.D4, 1)  
        SetDevicePower("{98C5250D-C29A-4985-AE5F-AFE5367E5006}\cardname", 1, CEDEVICE_POWER_STATE.D4)  
        Application.DoEvents()  
    Catch  
    End Try  
End Sub 

但在Wondows Phone 8.1中,我不知道如何在 C#中做同样的事情。

我担心它不会以同样的方式支持吗?

这是我在C#中尝试的:

    [DllImport("coredll.dll")]
    public static extern int DevicePowerNotify(string device, CEDEVICE_POWER_STATE state, int flags);

    [DllImport("coredll.dll")]
    public static extern int SetDevicePower(string pvDevice, int df, CEDEVICE_POWER_STATE ds);

    public static void wifi_power_on()
    {
        try
        {
            DevicePowerNotify("{98C5250D-C29A-4985-AE5F-AFE5367E5006}\\cardName", CEDEVICE_POWER_STATE.D0, 1);
            SetDevicePower("{98C5250D-C29A-4985-AE5F-AFE5367E5006}\\cardName", 1, CEDEVICE_POWER_STATE.D0);
            Application.DoEvents();
        }
        catch
        {
        }

    }

    public static void wifi_power_off()
    {
        try
        {
            DevicePowerNotify("{98C5250D-C29A-4985-AE5F-AFE5367E5006}\\cardName", CEDEVICE_POWER_STATE.D4, 1);
            SetDevicePower("{98C5250D-C29A-4985-AE5F-AFE5367E5006}\\cardName", 1, CEDEVICE_POWER_STATE.D4);
            Application.DoEvents();
        }
        catch
        {
        }
    }

在Windows Phone(从7.0到当前版本8.1的所有版本)中,无法以编程方式关闭或打开WiFi。这是因为平台始终将这些设置留在用户的控件中。

您最接近的是以编程方式启动WiFi设置页面,用户可以在其中修改设置:

await Launcher.LaunchUriAsync(new Uri("ms-settings-wifi:"));
