  您可以像@Jason链接到的示例代码那样执行此操作 . 但是目前在当前版本的MonoTouch中没有 CaptiveNetwork 的绑定（但它将包含在未来的beta版本中） .

  在此期间，您可以在应用程序中复制粘贴以下代码以获取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 ();
  }
