How to read console output with buffer (pipe)

You can re-direct outputs of the console application into some streams you can provide by yourself. Use System.Diagnostics.Process.Start(ProcessStartInfo).

You can re-direct two output streams: System.Diagnostics.Process.StandardError and System.Diagnostics.Process.StandardOutput. You need to use System.Diagnostics.ProcessStartInfo in order to specify System.Diagnostics.ProcessStartInfo.RedirectStandardError or System.Diagnostics.ProcessStartInfo.RedirectStandardErrorRedirectStandardOutput.

You can use file stream for redirection of StandardError or StandardOutput or some other stream, as these properties should of the type System.IO.StreamReader. You can create your own class derived from System.IO.StreamReader or use its constructor accepting the parameter of the abstract class System.IO.Stream, so you can also use your own stream class derived from System.IO.Stream. In this way, you can implement any stream type to your requirements to be used for stream re-direction.

(One typical example of this re-direction feature is running a compiler or а linker (or other tool used for a build step) under IDE, where a compiler or а linker output (errors and warnings, in particular) is displayed in IDE control immediately as the build goes.)
