C#获取系统网络使用情况

Question

我需要一种方法来获取当前系统网络使用情况的上下变化。

我在网上找到了一些，但它们不适合我。

谢谢你的帮助

代码片段:

 private void timerPerf_Tick(object sender, EventArgs e)
        {
            if (!NetworkInterface.GetIsNetworkAvailable())
                return;

            NetworkInterface[] interfaces
                = NetworkInterface.GetAllNetworkInterfaces();

            foreach (NetworkInterface ni in interfaces)
            {
                this.labelnetup.Text = "    Bytes Sent: " + ni.GetIPv4Statistics().BytesSent;
                this.labelnetdown.Text = "    Bytes Rec: " + ni.GetIPv4Statistics().BytesReceived;
            }

        }

请参阅Report information from NetworkInterface: network statistics对于一个好的示例程序:

using System;
using System.Net.NetworkInformation;

class MainClass
{
    static void Main()
    {
        if (!NetworkInterface.GetIsNetworkAvailable())
           return;

        NetworkInterface[] interfaces 
            = NetworkInterface.GetAllNetworkInterfaces();

        foreach (NetworkInterface ni in interfaces)
        {                
            Console.WriteLine("    Bytes Sent: {0}", 
                ni.GetIPv4Statistics().BytesSent);
            Console.WriteLine("    Bytes Received: {0}",
                ni.GetIPv4Statistics().BytesReceived);
        }
    }
}
