实现使用C#代码完成wifi的切换和连接功能
代码如下：

namespace Wifi连接器
{public partial class Form1 : Form{private List<Wlan.WlanAvailableNetwork> NetWorkList = new List<Wlan.WlanAvailableNetwork>();private WlanClient.WlanInterface WlanIface;public Form1(){InitializeComponent();}void WlanIface_WlanConnectionNotification(Wlan.WlanNotificationData notifyData, Wlan.WlanConnectionNotificationData connNotifyData){if (notifyData.notificationSource == NativeWifi.Wlan.WlanNotificationSource.MSM){//这里是完成连接if ((NativeWifi.Wlan.WlanNotificationCodeMsm)notifyData.NotificationCode == NativeWifi.Wlan.WlanNotificationCodeMsm.Connected){Invoke(new Action(() =>{label2.Text = connNotifyData.profileName;}));}}else if (notifyData.notificationSource == NativeWifi.Wlan.WlanNotificationSource.ACM){//连接失败if ((NativeWifi.Wlan.WlanNotificationCodeAcm)notifyData.NotificationCode == NativeWifi.Wlan.WlanNotificationCodeAcm.ConnectionAttemptFail){Invoke(new Action(() =>{label2.Text = "未连接";}));MessageBox.Show("连接失败，请检查密码是否正确");WlanIface.DeleteProfile(connNotifyData.profileName);}if ((NativeWifi.Wlan.WlanNotificationCodeAcm)notifyData.NotificationCode == NativeWifi.Wlan.WlanNotificationCodeAcm.Disconnected){Invoke(new Action(() =>{label2.Text = "未连接";}));}if ((NativeWifi.Wlan.WlanNotificationCodeAcm)notifyData.NotificationCode == NativeWifi.Wlan.WlanNotificationCodeAcm.Disconnecting){Invoke(new Action(() =>{label2.Text = "未连接";}));}if ((NativeWifi.Wlan.WlanNotificationCodeAcm)notifyData.NotificationCode == NativeWifi.Wlan.WlanNotificationCodeAcm.ConnectionStart){Invoke(new Action(() =>{label2.Text = "连接中…";}));}}}private void Form1_Load(object sender, EventArgs e){WlanClient client = new WlanClient();WlanIface = client.Interfaces[0];//一般就一个网卡，有2个没试过。WlanIface.WlanConnectionNotification += WlanIface_WlanConnectionNotification;LoadNetWork();}private void LoadNetWork(){System.Int32 dwFlag = new Int32();Wlan.WlanAvailableNetwork[] networks = WlanIface.GetAvailableNetworkList(0);foreach (Wlan.WlanAvailableNetwork network in networks){string SSID = WlanHelper.GetStringForSSID(network.dot11Ssid);if (network.flags.HasFlag(Wlan.WlanAvailableNetworkFlags.Connected)){label2.Text = SSID;}//如果有配置文件的SSID会重复出现。过滤掉if (!listBox1.Items.Contains(SSID)){listBox1.Items.Add(SSID);NetWorkList.Add(network);}}//信号强度排序NetWorkList.Sort(delegate(Wlan.WlanAvailableNetwork a, Wlan.WlanAvailableNetwork b){return b.wlanSignalQuality.CompareTo(a.wlanSignalQuality);});listBox1.Items.Clear();foreach (Wlan.WlanAvailableNetwork network in NetWorkList){listBox1.Items.Add(WlanHelper.GetStringForSSID(network.dot11Ssid));}}private void button1_Click(object sender, EventArgs e){Wlan.WlanAvailableNetwork wn = NetWorkList[listBox1.SelectedIndex];if (wn.securityEnabled && !WlanHelper.HasProfile(WlanIface, WlanHelper.GetStringForSSID(wn.dot11Ssid))){Form_Password fp = new Form_Password();if (fp.ShowDialog() == DialogResult.OK){string pw = fp.Password;WlanHelper.ConnetWifi(WlanIface, wn, pw);fp.Dispose();}}else{WlanHelper.ConnetWifi(WlanIface, wn);}}private void listBox1_SelectedIndexChanged(object sender, EventArgs e){Wlan.WlanAvailableNetwork wn = NetWorkList[listBox1.SelectedIndex];toolTip1.SetToolTip(listBox1, WlanHelper.GetWifiToolTip(wn));}private void label3_Click(object sender, EventArgs e){NetWorkList.Clear();listBox1.Items.Clear();LoadNetWork();}}
}
