计算带宽

Question

有没有办法可以通过网络计算exe /应用程序的带宽(发送和接收的数据包)？已经陷入了IPGlobalProperties,

和其他类....我想要由单个应用程序收到的数据包发送...我已经检查了http://netstatagent.com/ 我需要类似的东西... .net中有什么可以帮助我吗？

我的应用程序连接到Web服务以发送一些图像文件...并且还接收文件...

一种方法是为您的应用程序检索性能计数器 ".NET CLR Networking/Bytes Received"和".NET CLR Networking/Bytes Sent"的值:

PerformanceCounter bytesSentPerformanceCounter= new PerformanceCounter();
bytesSentPerformanceCounter.CategoryName = ".NET CLR Networking";
bytesSentPerformanceCounter.CounterName = "Bytes Sent";
bytesSentPerformanceCounter.InstanceName = GetInstanceName();
bytesSentPerformanceCounter.ReadOnly = true;

float bytesSent = bytesSentPerformanceCounter.NextValue();

//....

private static string GetInstanceName()
{
  // Used Reflector to find the correct formatting:
  string assemblyName = GetAssemblyName();
  if ((assemblyName == null) || (assemblyName.Length == 0))
  {
    assemblyName = AppDomain.CurrentDomain.FriendlyName;
  }
  StringBuilder builder = new StringBuilder(assemblyName);
  for (int i = 0; i < builder.Length; i++)
  {
    switch (builder[i])
    {
      case '/':
      case '\\':
      case '#':
        builder[i] = '_';
        break;
      case '(':
        builder[i] = '[';
        break;

      case ')':
        builder[i] = ']';
        break;
    }
  }
  return string.Format(CultureInfo.CurrentCulture, 
                       "{0}[{1}]", 
                       builder.ToString(), 
                       Process.GetCurrentProcess().Id);
}

private static string GetAssemblyName()
{
  string str = null;
  Assembly entryAssembly = Assembly.GetEntryAssembly();
  if (entryAssembly != null)
  {
    AssemblyName name = entryAssembly.GetName();
    if (name != null)
    {
      str = name.Name;
    }
  }
  return str;
}

请注意,性能计数器 在第一次使用相关网络库之前不会创建(您将获得InvalidOperation:指定类别中不存在实例'XXX')并且您需要插入

<configuration>
  <system.net>
    <settings>
      <performanceCounters enabled="true" />
    </settings>
  </system.net>
</configuration>

在你的app.config中.
