How to get Id of a process by port number using Get-Process powershell command – Asp.net

I need to kill a process which does not list when I use the netstat command. The following command will find the process id of 4 which is not the one that I am looking for.

    $processPID =  $($(netstat -aon | findstr '5000')[0] -split 's+')[-1]
    Stop-Process $processPID

I know the process that I need is in the results of the following.

Get-Process -Name dotnet

And I can’t find a way to use the Get-Process to use with the port filter. For the information of dotnet people, I am running the project using the dotnet CLI command from powershell.

In the screenshot below, you can see the process id for the process listening on port
5100

    Thanks to @Mathias and @Sebastian. With your valuable inputs I came up with the following function to get the process id.

        function Get-ProcessByPort {
    param(
        [int]$Port
    )
    $services = netsh http show servicestate
    $positionSession=0
    $countSession=0
    $countProcess=0
    [bool] $takeNextPID=0
    $processId=$null
    foreach ($s in $services){
        if ($takeNextPID -eq 1) {
            $processId=$s
            break
        }
        if ($s -match 'Server session ID') {
            $countSession++
        }
        if ($s -match "HTTP://LOCALHOST:$Port/") {
            $positionSession=$countSession
        }
        if ($s -match 'Process IDs:') {
            $countProcess++
        }
        if ($positionSession -gt 0) {
            if ($countProcess -eq $positionSession) {
                $takeNextPID=1
            }
        }
    }
    if (-not ([string]::IsNullOrEmpty($processId)))
    {
        $processId=$processId.Trim()
    }   
    return $processId
}

    Use the Get-NetTCPConnection cmdlet to get the same output as netstat, but as structured objects instead of text:

    Get-NetTCPConnect -LocalPort 5000 |Get-Process -Id {$_.OwningProcess} -IncludeUsername:$false

    As above, here’s a function for getting the PID depending if this is either a LocalPort or RemotePort.

    function Get-ProcessByPort {
    param(
        [int]$Port,
        [ValidateSet('LocalPort', 'RemotePort')]
        [string]$PortType = 'LocalPort'
    )

    $splat = @{
        $PortType = $Port
    }

    $processes = Get-NetTCPConnection @splat | Select-Object -ExpandProperty OwningProcess | ForEach-Object { Get-Process -Id $_ } | Select-Object -Unique
    return $processes | Select-Object -ExpandProperty Id
}
