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();
}
}
}
