如何检查谁在C#中使用某些端口? [英] How to check who uses certain port in C#?

问题描述

如何确定正在使用哪个进程/可执行文件，例如本地主机的端口80?我想知道，例如它是否是Apache Server等.

How to determine what process/what executable is using, say, port 80 of my localhost? I would like to know, for example if it is Apache Server, etc.

我们可以从ipProperties.GetActiveTcpListeners()获得一些信息吗?我只看到本地端点，远程端点和状态.

Can we get some information from ipProperties.GetActiveTcpListeners() ? I've only seen local endpoint, remote endpoint and state.

推荐答案

您可以通过管道传输netstat -o的输出并对其进行解析，但这可能是一个充满头痛和极端情况的可怕主意.

You can pipe the output of netstat -o and parse it, but that's probably a terrible idea full of headaches and edge cases.

在后台，netstat -o使用 GetTcpTable2 API方法，该方法返回MIB_TCPTABLE2结构，每个端口均由MIB_TCPROW2结构表示.您必须使用P/Invoke从C#中访问此代码，为表和行构建互操作结构

Behind the scenes, netstat -o uses the GetTcpTable2 API method from the IPHelper library, which returns a MIB_TCPTABLE2 structure, with each port represented by a MIB_TCPROW2 structure. You'll have to use P/Invoke to access this from C#, building interop structs for the table and the row

检查PInvoke.Net，我发现类似的API调用已经映射到C#- GetExtendedTcpTable -列出了应用程序的可用TCP端口.您可以将其用作构建互操作结构和声明的基础.

Checking PInvoke.Net, I see that a similar API call has already been mapped to C# - GetExtendedTcpTable - which lists available TCP ports for an app. You can use that as a base for building your interop structs and declarations.
