以c＃編程方式查詢網卡的入站/出站IPv4數據包計數統計信息＃

Question

我想獲取有關網卡的發送和接收數據包計數（IP級別：包括TCP，UDP等）的統計信息。

如何從Windows查詢信息？

Answer 1

你可以看看Pcap.Net。

Getting the list of Live Devices on the local host. 
Reading packets from Live Devices (Network Devices) and Offline Devices (Files) using the different WinPcap methods. 
Receiving statistics on the entire capture. 
Receiving statistics of packets instead of the full packets. 
Using different sampling methods. 
Applying Berkley Packet Filters. 
Sending packets to Live Devices directly or using WinPcap's send queues. 
Dumping packets to Pcap files. 
Using Enumerables to receive packets (and LINQ). 

注意WinPcap的驅動程序必須在系統上安裝。

Answer 2

WMI。

不容易從C＃使用，但可能的。

Answer 3

首先，你必須

using System.Net.NetworkInformation; 

接下來，您必須：

var iFaceArr = NetworkInterface.GetAllNetworkInterfaces(); 
NetworkInterface iface = iFaceArr[0]; 
IPv4InterfaceStatistics iFaceStats = iface.GetIPv4Statistics(); 

然後你有這些變量：

iFaceStats.UnicastPacketsReceived; 
iFaceStats.UnicastPacketsSent; 
iFaceStats.NonUnicastPacketsReceived; 
iFaceStats.NonUnicastPacketsSent;
