在SharpPCap如何找到设备的IP地址？ [英] In SharpPCap How do I find the IP Address of the Device?

问题描述

我使用的是WinPCapDevice并已初始化它。我只想能够从该设备获得IP，我找不到任何地方如何提取设备的IP地址。如果心不是一个办法做到这一点则有另一种方式来获得一个WinPCapDevice的IP地址，以便我可以检查它反对IPAddresses列表？

下面是该小块的，我讲的代码

  IPHostEntry主机; 
主机= Dns.GetHostEntry（Dns.GetHostName（））; 
 
的foreach（在host.AddressList ip地址IP）
 {
如果（ip.AddressFamily.ToString（）==网间）
 {
 
 localIPAddress = ip.ToString（）; 
 //想检查我的WinPCapDevice设备的IP等于ip的
} 
} 
  

解决方案

的 WinPcapDevice 类包含一个名为地址属性。这个属性保存与设备相关联的所有地址（IP）：

 字符串localIPAddress =...; 
 
 WinPcapDeviceList设备= WinPcapDeviceList.Instance; 
 
的foreach（WinPcapDevice开发中的设备）
 {
 Console.Out.WriteLine（{0}，dev.Description）; 
 
的foreach（在dev.Addresses PcapAddress地址）
 {
如果（addr.Addr = NULL&放大器;！&安培;！addr.Addr.ipAddress = NULL）
 {
 Console.Out.WriteLine（addr.Addr.ipAddress）; 
 
如果（localIPAddress == addr.Addr.ipAddress.ToString（））
 {
 Console.Out.WriteLine（捕捉设备中找到）; 
} 
} 
} 
} 
  

中当然，你也可以使用 CaptureDeviceList 类来获得特定设备的列表。在此列表中的每个工具设备 ICaptureDevice 。那么你必须转换为 WinPcapDevice ，一个 LibPcapLiveDevice 或 AirPcapDevice 以访问地址属性。

希望，这有助于。

I am using a WinPCapDevice and have already initialized it. I just want to be able to get the IP from that device and I cannot find anywhere how to extract the IP address of the Device. If there isnt a way to do it then is there another way to get the IP address of a WinPCapDevice so that I can check it against a list of IPAddresses?

Here is the small chunk of code that I am talking about.

        IPHostEntry host;
        host = Dns.GetHostEntry(Dns.GetHostName());

        foreach (IPAddress ip in host.AddressList)
        {
            if (ip.AddressFamily.ToString() == "InterNetwork")
            {

                localIPAddress = ip.ToString();
                //Want to check if my WinPCapDevice device's IP is equal to ip
            }
        }

解决方案

The WinPcapDevice class contains a property called Addresses. This property holds all addresses (IP) associated with the device:

string localIPAddress = "...";

WinPcapDeviceList devices = WinPcapDeviceList.Instance;

foreach(WinPcapDevice dev in devices)
{
  Console.Out.WriteLine("{0}", dev.Description);

  foreach(PcapAddress addr in dev.Addresses)
  {
    if(addr.Addr != null && addr.Addr.ipAddress != null)
    {
      Console.Out.WriteLine(addr.Addr.ipAddress);

      if(localIPAddress == addr.Addr.ipAddress.ToString())
      {
        Console.Out.WriteLine("Capture device found");           
      }
    }
  }
}

Of course, you could also use the CaptureDeviceList class to get a list of specific devices. Every device in this list implements ICaptureDevice. You then have to cast to a WinPcapDevice, a LibPcapLiveDevice or a AirPcapDevice in order to access the Address property.

Hope, this helps.
