I have a C# console application that reads .csv files. I want to run this in the middle of a powershell script. What is the best way to do this?

Use Start-Process, perhaps with the -PassThru option, for example:

$csvProc = Start-Process my_csv_reader.exe -PassThru

This would allow you to do something like $csvProc | Stop-Process later on, or to check if it's still running at a later point in your script through $csvProc.HasExited

If you need even more control, you could do it this way:

$csvProc = New-Object System.Diagnostics.ProcessStartInfo

and then you can use $csvProc the same way you'd use ProcessStartInfo in C# (setting the file name, paramaters, redirecting standard in or out, starting the process, etc.).

If your executable isn't in your path you will need to tell powershell where to find it.

& "c:\some path with spaces\foo.exe" <arguments go here>

This has been answered before, here: Executing an EXE file using a PowerShell script

Easy:

Start-Process -Wait PathToFile

If you don't want to wait for the process to finish remove the "-Wait" switch.
