	While you can redirect standard output of WinSCP process, it is actually not very useful, as output of WinSCP does not have any predefined form (cannot be parsed). Though it can be useful to capture it, in case you want to show it to a user in your GUI or for diagnostic purposes.

-	If you want to collect the output, redirect the standard output before starting WinSCP (''[[dotnet>system.diagnostics.processstartinfo.redirectstandardoutput\|ProcessStartInfo.RedirectStandardOutput]]'') and read from output stream (''[[dotnet>system.diagnostics.process.standardoutput\|Process.StandardOutput]]''). You need to collect the output before calling ''[[dotnet>system.diagnostics.process.waitforexit\|Process.WaitForExit]]''. The output stream has limited capacity. Once it gets filled, WinSCP hangs waiting for free space, never finishing.	+	If you want to collect the output, redirect the standard output before starting WinSCP (''[[dotnet>system.diagnostics.processstartinfo.redirectstandardoutput\|ProcessStartInfo.RedirectStandardOutput]]'') and read from output stream (''[[dotnet>system.diagnostics.process.standardoutput\|Process.StandardOutput]]''). You need to continously collect the output while the script is running. The output stream has limited capacity. Once it gets filled, WinSCP hangs waiting for free space, never finishing. That means you cannot use ''[[dotnet>system.diagnostics.process.waitforexit\|Process.WaitForExit]]'' on its own to wait for script to finish. Convenient alternative is ''[[dotnet>system.io.streamreader.readtoend\|StreamReader.ReadToEnd]]'':
