我正在尝试学习如何监视特定应用程序的网络带宽使用情况。 我正在查看IPv4InterfaceStatistics
,但这似乎监视了 NIC 卡的性能。
我想监视特定的应用程序,以查看每秒消耗多少带宽。
有谁知道如何做到这一点的例子?
using System;
using System.Diagnostics;
using System.Globalization;
using System.IO;
using System.Net;
using System.Net.Sockets;
using System.Reflection;
using System.Text;
using System.Threading;
namespace ConsoleApplication2
{
class Program
{
static void Main(string[] args)
{
while (true)
{
var bytesSentPerformanceCounter = new PerformanceCounter();
bytesSentPerformanceCounter.CategoryName = ".NET CLR Networking";
bytesSentPerformanceCounter.CounterName = "Bytes Sent";
bytesSentPerformanceCounter.InstanceName = GetInstanceName();
bytesSentPerformanceCounter.ReadOnly = true;
var bytesReceivedPerformanceCounter = new PerformanceCounter();
bytesReceivedPerformanceCounter.CategoryName = ".NET CLR Networking";
bytesReceivedPerformanceCounter.CounterName = "Bytes Received";
bytesReceivedPerformanceCounter.InstanceName = GetInstanceName();
bytesReceivedPerformanceCounter.ReadOnly = true;
Console.WriteLine("Bytes sent: {0}", bytesSentPerformanceCounter.RawValue);
Console.WriteLine("Bytes received: {0}", bytesReceivedPerformanceCounter.RawValue);
Thread.Sleep(1000);
}
}
private static string GetInstanceName()
{
string returnvalue = "not found";
//Checks bandwidth usage for CUPC.exe..Change it with your application Name
string applicationName = "CUPC";
PerformanceCounterCategory[] Array = PerformanceCounterCategory.GetCategories();
for (int i = 0; i < Array.Length; i++)
{
if (Array[i].CategoryName.Contains(".NET CLR Networking"))
foreach (var item in Array[i].GetInstanceNames())
{
if (item.ToLower().Contains(applicationName.ToString().ToLower()))
returnvalue = item;
}
}
return returnvalue;
}
}
}
下面是使用性能计数器的修改版本:
var processFileName = Path.GetFileName(Process.GetCurrentProcess().MainModule.FileName);
var bytesReceivedPerformanceCounter = new PerformanceCounter();
bytesReceivedPerformanceCounter.CategoryName = ".NET CLR Networking 4.0.0.0";
bytesReceivedPerformanceCounter.CounterName = "Bytes Received";
bytesReceivedPerformanceCounter.InstanceName = VersioningHelper.MakeVersionSafeName(processFileName, ResourceScope.Machine, ResourceScope.AppDomain);
bytesReceivedPerformanceCounter.ReadOnly = true;
Console.WriteLine("Bytes received: {0}", bytesReceivedPerformanceCounter.RawValue);
如果您
熟悉 OSI 模型 http://en.wikipedia.org/wiki/OSI_model 您会看到您尝试与应该与第 7 层交互的第 3 层进行交互。
我与你正在使用的任何类的连接,你都能够测量发送的字节数,特别是如果你正在传输单个字节,(这是因为我不知道你的代码看起来如何),你应该能够计算字节数在时间除以秒数,你会得到你的结果。
