Get SSID of the wireless network I am connected to with C# .Net on Windows Vista
提问by mariosangiorgio
I'd like to know if there is any .Net class that allows me to know the SSID of the wireless network I'm connected to. So far I only found the library linked below. Is the best I can get or should I use something else? Managed WiFi(http://www.codeplex.com/managedwifi)
我想知道是否有任何 .Net 类可以让我知道我连接到的无线网络的 SSID。到目前为止，我只找到了下面链接的库。是我能得到的最好的还是应该使用其他的？ 托管 WiFi( http://www.codeplex.com/managedwifi)
The method that exploits WMIworks for Windows XP but is it not working anymore with Windows Vista.
利用WMI的方法适用于 Windows XP，但它不再适用于 Windows Vista。

I resolved using the library. It resulted to be quite easy to work with the classes provided:
我解决了使用库。结果很容易使用提供的类：
First I had to create a WlanClient object
首先我必须创建一个 WlanClient 对象
wlan = new WlanClient();
And then I can get the list of the SSIDs the PC is connected to with this code:
然后我可以使用以下代码获取 PC 连接到的 SSID 列表：
Collection<String> connectedSsids = new Collection<string>();
foreach (WlanClient.WlanInterface wlanInterface in wlan.Interfaces)
{
Wlan.Dot11Ssid ssid = wlanInterface.CurrentConnection.wlanAssociationAttributes.dot11Ssid;
connectedSsids.Add(new String(Encoding.ASCII.GetChars(ssid.SSID,0, (int)ssid.SSIDLength)));
}

It looks like this will do what you want:
看起来这会做你想做的：
ManagementObjectSearcher searcher = new ManagementObjectSearcher("root\WMI",
"SELECT * FROM MSNdis_80211_ServiceSetIdentifier");
foreach (ManagementObject queryObj in searcher.Get())
{
Console.WriteLine("-----------------------------------");
Console.WriteLine("MSNdis_80211_ServiceSetIdentifier instance");
Console.WriteLine("-----------------------------------");
if(queryObj["Ndis80211SsId"] == null)
Console.WriteLine("Ndis80211SsId: {0}",queryObj["Ndis80211SsId"]);
else
{
Byte[] arrNdis80211SsId = (Byte[])
(queryObj["Ndis80211SsId"]);
foreach (Byte arrValue in arrNdis80211SsId)
{
Console.WriteLine("Ndis80211SsId: {0}", arrValue);
}
}
}

You are going to have to use native WLAN API. There is a long discussion about it here. Apparently this is what Managed Wifi API uses, so it will be easier for you to use it if you do not have any restrictions to use LGPL code.
您将不得不使用本机 WLAN API。有一个关于它的长时间的讨论在这里。显然这是 Managed Wifi API 所使用的，因此如果您对使用 LGPL 代码没有任何限制，那么使用它会更容易。

there is some more information in How do I get the available wifi APs and their signal strength in .net?

We were using the managed wifi library, but it throws exceptions if the network is disconnected during a query.
我们使用的是托管 wifi 库，但如果在查询期间网络断开，它会抛出异常。
Try:
尝试：
var process = new Process
{
StartInfo =
{
FileName = "netsh.exe",
Arguments = "wlan show interfaces",
UseShellExecute = false,
RedirectStandardOutput = true,
CreateNoWindow = true
}
};
process.Start();
var output = process.StandardOutput.ReadToEnd();
var line = output.Split(new[] { Environment.NewLine }, StringSplitOptions.RemoveEmptyEntries).FirstOrDefault(l => l.Contains("SSID") && !l.Contains("BSSID"));
if (line == null)
{
return string.Empty;
}
var ssid = line.Split(new[] { ":" }, StringSplitOptions.RemoveEmptyEntries)[1].TrimStart();
return ssid;

I found a rather old library dating back to 2014:
我发现了一个可以追溯到 2014 年的相当古老的图书馆：
Microsoft.WindowsAPICodePack-Core version 1.1.0.2
Although it is not conforming to .NET Standard, this library integrates with my .NET Core 3.0 app, but obviously is not cross-platform.
虽然它不符合 .NET Standard，但该库与我的 .NET Core 3.0 应用程序集成，但显然不是跨平台的。
Sample code:
示例代码：
var networks = NetworkListManager.GetNetworks(NetworkConnectivityLevels.Connected);
foreach (var network in networks) {
sConnected = ((network.IsConnected == true) ? " (connected)" : " (disconnected)");
Console.WriteLine("Network : " + network.Name + " - Category : " + network.Category.ToString() + sConnected);
}

I wanted to do exactly this, and tried using ManagedWifi, as suggested in other answers. But that led to unresolvable Exceptions as per here: Issues with using Managed WiFi (NativeWiFi API)
我想完全做到这一点，并按照其他答案中的建议尝试使用 ManagedWifi。但这导致了无法解决的异常，如下所示： Issues with using Managed WiFi (NativeWiFi API)
I solved this by switching to using SimpleWiFientirely and ignored the ManagedWifi package.
我通过完全切换到使用SimpleWiFi解决了这个问题，并忽略了 ManagedWifi 包。
Glancing at the source code, it looks like SW is a fixed reimplementation of some of the functionality in MW.
看一下源代码，看起来 SW 是 MW 中某些功能的固定重新实现。
