C++ 获取 Windows 10 资源监视器中网络活动的进程流量

要获取 Windows 10 下资源监视器中网络活动的进程网络发送与接收流量，可以使用 Windows API 来实现。以下是一个示例代码：

#include <iostream>
#include <Windows.h>
#include <Psapi.h>

int main()
{
    // 获取所有进程的 ID
    DWORD processes[1024], cbNeeded, cProcesses;
    if (!EnumProcesses(processes, sizeof(processes), &cbNeeded))
    {
        std::cout << 'Failed to enumerate processes.' << std::endl;
        return 1;
    }

    // 计算进程数量
    cProcesses = cbNeeded / sizeof(DWORD);

    // 遍历每个进程
    for (DWORD i = 0; i < cProcesses; i++)
    {
        // 打开进程
        HANDLE hProcess = OpenProcess(PROCESS_QUERY_INFORMATION | PROCESS_VM_READ, FALSE, processes[i]);
        if (hProcess != NULL)
        {
            // 获取进程名字
            char szProcessName[MAX_PATH];
            if (GetModuleBaseNameA(hProcess, NULL, szProcessName, sizeof(szProcessName)) != 0)
            {
                // 获取进程的网络信息
                MIB_TCPROW_OWNER_PID tcpRow;
                tcpRow.dwOwningPid = processes[i];
                if (GetExtendedTcpTable(&tcpRow, sizeof(tcpRow), TRUE, AF_INET, TCP_TABLE_OWNER_PID_ALL, 0) == NO_ERROR)
                {
                    // 输出进程名字和发送/接收流量
                    std::cout << 'Process Name: ' << szProcessName << std::endl;
                    std::cout << 'Sent Bytes: ' << tcpRow.dwBytesSent << std::endl;
                    std::cout << 'Received Bytes: ' << tcpRow.dwBytesReceived << std::endl;
                    std::cout << std::endl;
                }
            }

            // 关闭进程句柄
            CloseHandle(hProcess);
        }
    }

    return 0;
}
