You can view these with Process Explorer from sysinternals. Use the "Find -> Find Handle or DLL..." option and enter the pattern "\Device\NamedPipe\". It will show you which processes have which pipes open.

Use pipelist.exe from Sysinternals.

C#:

String[] listOfPipes = System.IO.Directory.GetFiles(@"\\.\pipe\");

Try the following instead:

String[] listOfPipes = System.IO.Directory.GetFiles(@"\\.\pipe\");

The second pipe was interpreted by this web site when submitted... You need two backslashes at the beginning. So make sure to use System.IO.Directory.GetFiles(@"\\.\pipe\").

Note that I have seen this function call throw an 'illegal characters in path.' exception when one of the pipes on my machine had invalid characters. PipleList.exe worked ok though, so it seems like a bug in MS's .NET code.

In the Windows Powershell console, type

[System.IO.Directory]::GetFiles("\\.\\pipe\\")

If your OS version is greater than Windows 7, you can also type

get-childitem \\.\pipe\

This returns a list of objects. If you want the name only:

(get-childitem \\.\pipe\).FullName

In Powershell 7, the second example \\.\pipe\ does not work (see this known bug), so you will have to stick to the first syntax.

I stumbled across a feature in Chrome that will list out all open named pipes by navigating to "file://.//pipe//"

Since I can't seem to find any reference to this and it has been very helpful to me, I thought I might share.

At CMD prompt:

Microsoft Windows [Version 10.0.18362.476]


>dir \\.\pipe\\
