从特定进程获取字节 [英] Get byte from specific process

问题描述

嗨
我写这段代码：

 PerformanceCounter pc =  new  PerformanceCounter（  .NET CLR Networking， 接收的字节数， 系统）; 
 
 Console.WriteLine（pc.RawValue）; 
 Console.ReadLine（）; 

为什么我收到错误：

 System.InvalidOperationException：'计数器是单个实例，实例名称'系统'对此计数器类别无效。'

< b>我尝试了什么：



我试试这个链接：我不能

解决方案

您可能需要使用其他类别网络接口 ，请看这里的答案：

网络 - 如何在C＃中显示每秒接收的字节数 - 堆栈溢出 [ ^ ]

但这不是特定于流程特定的......



替代方案可能是使用 TCPView 实用程序并使用其输出，请参阅： TCPView for Windows - Windows Sysinternals | Microsoft Docs [ ^ ]

Hi I write this code:

PerformanceCounter pc = new PerformanceCounter(".NET CLR Networking", "Bytes Received", "System" );

            Console.WriteLine(pc.RawValue);
            Console.ReadLine();

Why i get error:

System.InvalidOperationException: 'Counter is single instance, instance name 'System' is not valid for this counter category.'

What I have tried:

I try by this link: and i can't

解决方案

You probably need to use another category 'Network Interface', see the answer here:
networking - How to display bytes received per second in C# - Stack Overflow[^]
But this is not process specific sadly ...

An alternative might be using the TCPView utility and using the output of that, see: TCPView for Windows - Windows Sysinternals | Microsoft Docs[^]
