有没有一种方法来检测我使用的是什么类型的连接？ WIFI，3G或以太网？ [英] Is there a way to detect what kind of connection I'm using ? WiFi, 3G or Ethernet?

问题描述

我试图发现什么样的网络连接，我连接。它是WiFi或3G？
是有办法做到这一点使用C＃赢形式的.NET 2.0或4.0？

 的foreach（在NetworkInterface的适配器适配器）
 {
如果（adapter.OperationalStatus == OperationalStatus.Up）
 {
如果（adapter.NetworkInterfaceType == NetworkInterfaceType.Wireless80211）
 {
 lblNetworkType.Text =您正在使用WiFi; 
中断; 
} 
，否则如果（adapter.NetworkInterfaceType == NetworkInterfaceType.Ppp）
 {
 lblNetworkType.Text =您正在使用3G或ADSL或拨号 
中断; 
} 
，否则如果（adapter.NetworkInterfaceType == NetworkInterfaceType.Ethernet）
 {
 lblNetworkType.Text =您使用的是以太网; 
中断; 
} 
} 
} 
  

解决方案

不幸的是，不是'整洁'的方式来做到这一点本身。 3G连接看起来一样的ADSL或拨号连接（与网络类型为PPP）。

如果你确信你永远只能是在WiFi / 3G，那么你可以检查通过的的NetworkInterface 类的信息=http://msdn.microsoft.com/en-us/library/system .net.networkinformation.networkinterface.getallnetworkinterfaces.aspx相对=nofollow> GetAllNetworkInterfaces ，并把它作为3G如果接口类型为PPP。但正如我所说，这是其他类型的调制解调器连接的相同

编辑：你可能有一些运气寻找3G，HSPA，HSDPA 加密狗，在设备名称或说明。但this'd只能是一个体面的猜测而不是绝对肯定的。

I'm trying to detect what kind of network connection I'm connected to. is it WiFi or 3G? is there a way to do that using c# win forms .net 2.0 or 4.0 ?

        foreach (NetworkInterface adapter in adapters)
        {
            if (adapter.OperationalStatus == OperationalStatus.Up)
            {
                if (adapter.NetworkInterfaceType == NetworkInterfaceType.Wireless80211)
                {
                    lblNetworkType.Text = "you are using WiFi";
                    break;
                }
                else if (adapter.NetworkInterfaceType == NetworkInterfaceType.Ppp)
                {
                    lblNetworkType.Text = "you are using 3G or ADSL or Dialup";
                    break;
                }
                else if (adapter.NetworkInterfaceType == NetworkInterfaceType.Ethernet)
                {
                    lblNetworkType.Text = "you are using Ethernet";
                    break;
                }
            }
        }

解决方案

Unfortunately there isn't a 'neat' way to do this as such. A 3G connection will look the same as a ADSL or dialup connection (with the network type being PPP).

If you are certain that you'll only ever be on WiFi/3G, then you could check the information in the NetworkInterface class provided by GetAllNetworkInterfaces and treat it as 3G if the the interface type is PPP. But as I mentioned this is the same for other types of modem connection.

Edit: You may have some luck looking for "3G", "HSPA", "HSDPA", "Dongle" in the device name or description. But this'd only be a 'decent guess' rather than being absolutely certain.
