有没有一种方法可以获取和显示C#中应用程序设备的当前无线信号强度?我有一个应用程序可以通过计时器检测是否存在连通性,但是我需要知道当前信号强度,然后在状态栏中以图形方式显示它。下面是我当前的代码,每隔几秒钟检测一次基本连接。我还可以添加什么来显示强度?谢谢。计时器代码由S.O.用户:parapura rajkumar
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
最佳答案
经过研究并参考了其他一些问题之后,我能够通过以下网址提供的开源API解决我的问题:managedwifi.codeplex.com
只需下载api,然后通过add-> csproj将其添加到您的项目中即可。
使用WlanClient类中提供的“ public int RSSI”。

关于c# - 在Windows窗体上获取并显示网络信号强度,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/11953994/
