推荐答案

要检查Windows计算机上当前是否正在使用端口，请执行以下操作:
1)启动命令提示符.
2)在命令控制台中输入:
netstat -ano | findstr portNumber
这列出了行号中包含端口号的所有进程.
在行尾记下数字.这是进程ID(PID).
运行此PID的任务列表程序:
任务清单| findstr PID

还要检查此 [

To check if a port is currently in use on a Windows machine:
1)Start Command Prompt.
2)In the command console enter:
netstat -ano | findstr portNumber
This lists any processes where the port number is included somewhere on the line.
Make a note of the number at the end of the line. This is the process ID (PID).
Run the task-list program for this PID:
tasklist | findstr PID
