是否可以使用Xamarin以编程方式连接到Wi-Fi网络? [英] Is possible to programmatically connect to Wi-Fi network using Xamarin?

问题描述

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

Using Xamarin.iOS and Xamarin.Android, it is possible to check if the Wi-Fi is enabled? And, if is disabled, it's possible to enable it? Once it's enabled, how to search and connect to a network?

推荐答案

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();
