Opening console app using C# code in win forms

Question

I am trying to open the console application from my windows forms application. I have used the below code. The code is opening the Console application but not displaying anything (showing only black screen). But I am successfully able get the console output using StandardOutput.

Process proc = new Process();
proc.StartInfo.CreateNoWindow = false;
proc.StartInfo.UseShellExecute = false;
proc.StartInfo.RedirectStandardOutput = true;
proc.StartInfo.RedirectStandardError = true;
proc.StartInfo.RedirectStandardInput = true;
proc.StartInfo.FileName = @"C:\Program Filex86)\ConsoleTool.exe";

proc.Start();
StreamWriter sw = proc.StandardInput; 
sw.WriteLine("init");

txtOutput.Text += proc.StandardOutput.ReadToEnd().Replace("\n", "\r\n");

txtOutput.Text += proc.StandardError.ReadToEnd().Replace("\n", "\r\n");
proc.WaitForExit();

How to get the display on console window that is opened using code?

Please check your path. It has a ) in it. That maybe the reason you get a Black Screen!!!!!1 — Abhishek Kumar

for one you are redirecting the StandardOutput so it will never display any information in the Console's window. You will need to manually do it yourself, see stackoverflow.com/q/8787123/479512 and stackoverflow.com/questions/2547428/… — Mark Hall

@ Mark is there any way to display on console and get that data in my win form application ? — Niranjan NT

You have disconnected your console from all input and output and there is no way that I know to get the information back into it, you will need to do like Han's suggests in his accepted answer in the second link. — Mark Hall

Use AllocConsole function to open a console window and then use Console.WriteLine or other Console functions normally!

Example:

[System.Runtime.InteropServices.DllImport("kernel32")]  
extern static void AllocConsole();  
//....  
AllocConsole();  
Console.WriteLine("hello world");  
Console.ReadKey();
