C# sử dụng mạng hệ thống

Question

Tôi cần một cách để sử dụng mạng hệ thống hiện tại, lên và xuống.

Tôi tìm thấy một số trên mạng nhưng chúng không hoạt động đối với tôi.

Nhờ sự giúp đỡ của bạn

đoạn Code:

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; 
      } 

     } 

Answer 1

Xin xem Report information from NetworkInterface: network statistics cho một chương trình mẫu tốt:

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); 
     } 
    } 
}

Bạn có thể lấy sử dụng mạng hệ thống hiện tại bằng cách làm việc với PerformanceCounterCategory quá:

using System; 
using System.Diagnostics; 

class Program 
{ 
    static void Main() 
    { 
     PerformanceCounterCategory pcg = new PerformanceCounterCategory("Network Interface"); 
     string instance = pcg.GetInstanceNames()[0]; 
     PerformanceCounter pcsent = new PerformanceCounter("Network Interface", "Bytes Sent/sec", instance); 
     PerformanceCounter pcreceived = new PerformanceCounter("Network Interface", "Bytes Received/sec", instance); 

     Console.WriteLine("Bytes Sent: {0}", pcsent.NextValue()/1024);
