Bind and Listen on an Available Port in a Range

See more Socket/SSL/TLS Examples

Demonstrates Socket.BindAndListenPortRange, which searches an inclusive port range for an available TCP port, binds it, and begins listening. It returns the selected port, or -1 on failure.

Add-Type -Path "C:\chilkat\ChilkatDotNet47-x64\ChilkatDotNet47.dll"

$socket = New-Object Chilkat.Socket

#  Search the inclusive port range for an available TCP port, bind it, and begin listening.  The
#  method returns the selected port, or -1 when no port can be bound.
$boundPort = $socket.BindAndListenPortRange(5000,5100,25)
if ($boundPort -lt 0) {
    $($socket.LastErrorText)
    exit
