實驗結果

SharpPcap 採用了分層結構，在最頂層的是幾個管理所有裝置的類：

CaptureDeviceList——包含系統中所有裝置的列表

ICaptureDevice——所有繼承 ICaptureDevice 介面的裝置

通過執行下面一行程式碼，可以輕鬆獲得所有本機的所有網絡卡裝置：

CaptureDeviceListdevice_list = CaptureDeviceList.Instance;

在獲得網絡卡裝置以後，通過下面的 foreach 迴圈，就能將裝置資訊輸出到RichTextBox 中：

          foreach (ICaptureDevice dev in

              this.richTextBox1.Text+= string.Format("\n名稱：{0}\n閘道器：{1}\n描述：{2}\n", ((PcapDevice)dev).Interface.FriendlyName,((PcapDevice)dev).Interface.GatewayAddress, ((PcapDevice)dev).Interface.Description);
