推荐答案
如果您正在寻找与 netstat 相同的 WinAPI 方式.您可能需要以下 API:GetExtendedTcpTable
If you're looking for WinAPI way of doing the same as netstat. You probably want the following API:GetExtendedTcpTable
使用 TCP_TABLE_OWNER_PID_ALL 参数查找结果.
Look for the results with TCP_TABLE_OWNER_PID_ALL argument.
生成的 MIB_TCPTABLE_OWNER_PID 结构有许多 MIB_TCPROW_OWNER_PID 结构具有 dwOwningPid，这是您要查找的进程 ID.
The resulting MIB_TCPTABLE_OWNER_PID structure has many MIB_TCPROW_OWNER_PID structures that has dwOwningPid which is the process ID you are looking for.
