有没有一种方法可以获取并显示C#中应用程序设备的当前无线信号强度?我有一个应用程序检测是否有通过计时器连接,但我需要知道当前的信号强度,然后以图形方式显示在状态栏中。下面是我目前的代码,每隔几秒检测一次基本连接。我可以添加什么来显示力量呢?谢谢。计时器代码由S.O.给出。用户:parapura拉库玛获取并显示窗体上的网络信号强度
private void Form1_Load(object sender, EventArgs e)
{
//create an object to hold app settings FIRST
appsetting apps = new appsetting();
apps.getsetting();
netMessage.Clear();
//creates a timer for refresh rate on connectivity check
var timer = new Timer();
timer.Tick += new EventHandler(timer_Tick);
timer.Interval = 2000; //2 seconds
timer.Start();
}
//starts the timer
void timer_Tick(object sender, EventArgs e)
{
//if connection is not detected
if (System.Net.NetworkInformation.NetworkInterface.GetIsNetworkAvailable() ==f
false)
{
//clear the buffer
netMessage.Clear();
//turn RED indicator on and display message
netConnect.BackColor = Color.Red;
this.netMessage.Text = ("No Connection");
noConn = true;//set "No connection" to true
conn= false;
}
else
//turn GREEN indicator on and display message
netConnect.BackColor = Color.Lime;
this.netMessage.Text = ("Connected");
conn = true;// set connection to "true
noConn = false;
//if box is red but connection is established, turn it back to green
if (noConn == true &&
System.Net.NetworkInformation.NetworkInterface.GetIsNetworkAvailable() ==
true)
{
netConnect.BackColor = Color.Lime;
this.netMessage.Text = ("Connected");
conn = true;
noConn = false;
}
}
//need to display signal strength in a text box with color codes or status bar HERE
