android - 是否可以使用 Xamarin 以编程方式连接到 Wi-Fi 网络？

Question

使用 Xamarin.iOS 和 Xamarin.Android，可以检查 Wi-Fi 是否已启用？而且，如果被禁用，是否可以启用它？启用后，如何搜索并连接到网络？

Answer 1

启用/禁用 Wifi:

WifiManager wifiManager = (WifiManager)GetSystemService(WifiService);
if (!wifiManager.IsWifiEnabled)
    wifiManager.SetWifiEnabled(true);
else 
    wifiManager.SetWifiEnabled(false);

更改 Wifi 状态的权限:

android.permission.CHANGE_WIFI_STATE

添加网络:

var networkSSID = "Stack";
var networkPass = "Overflow";
var config = new WifiConfiguration();
config.Ssid = '"' + networkSSID + '"';

// For WPA/WPA2, WEP is different (still using WEP? shame on you ;-)
config.PreSharedKey = '"' + networkPass + '"';
wifiManager.AddNetwork(config);

连接到网络:

IList<WifiConfiguration> myWifi = wifiManager.ConfiguredNetworks;
wifiManager.Disconnect();
wifiManager.EnableNetwork(myWifi.FindFirst(x => x.Ssid.Contains(networkSSID)), true);
wifiManager.Reconnect();
