Question

C++ / C#

How to display process output stream?
When outputting a string there, it is necessary to display the string in this application in a timely manner

Answer 1

Example from MSDN

Process compiler = new Process();
compiler.StartInfo.FileName = "csc.exe";
compiler.StartInfo.Arguments = "/r:System.dll /out:sample.exe stdstr.cs";
compiler.StartInfo.UseShellExecute = false;
compiler.StartInfo.RedirectStandardOutput = true;
compiler.Start();    

Console.WriteLine(compiler.StandardOutput.ReadToEnd());

compiler.WaitForExit();

UseShellExecute must be set to False otherwise it won't work.
Similarly, compiler.StandardIntput can be used to provide input as if from a console.
