MonoTouch WIFI SSID

Question

是否有可能在IPhone上使用Monotouch连接WIFI SSID ?

我发现有可能检查Wi-Fi状态，但没有办法检查SSID。https://github.com/xamarin/monotouch-samples/blob/master/ReachabilitySample/reachability.cs有人知道怎么做吗?感谢大家的评论

您可以像@Jason链接到的样例代码那样做。但是目前MonoTouch的当前版本中还没有 captivennetwork 的绑定(但它将包含在未来的测试版中)。

同时，你可以在你的应用程序中复制粘贴以下代码来获得SSID。

    using System;
    using System.Runtime.InteropServices;
    using MonoTouch;
    using MonoTouch.CoreFoundation;
    using MonoTouch.Foundation;
    using MonoTouch.ObjCRuntime;
    [DllImport (Constants.SystemConfigurationLibrary)]
    extern static IntPtr CNCopyCurrentNetworkInfo (IntPtr interfaceName);
    static string GetSSID ()
    {
        IntPtr scl = Dlfcn.dlopen (Constants.SystemConfigurationLibrary, 0);
        try {
            using (NSString en0 = new NSString ("en0")) {
                using (NSDictionary dict = new NSDictionary (CNCopyCurrentNetworkInfo (en0.Handle))) {
                    using (NSString key = Dlfcn.GetStringConstant (scl, "kCNNetworkInfoKeySSID")) {
                        return dict [key].ToString ();
                    }
                }
            }
        }
        catch (EntryPointNotFoundException) {
            // this is not available when running on the simulator
            return String.Empty;
        }
        finally {
            Dlfcn.dlclose (scl);
        }
    }

UPDATE:最新的MonoTouch 5.2+版本包括对CaptiveNetwork的支持。以上代码简化为:

using MonoTouch.SystemConfiguration;
static string GetSSID ()
{
    var dict = CaptiveNetwork.CopyCurrentNetworkInfo ("en0");
    return dict [CaptiveNetwork.NetworkInfoKeySSID].ToString ();
}
