I had designed an application app.exe which reads the input from command prompt and will perform action accordingly.

To run that application I am executing the following command in command prompt:
"C:/Users/abhinay/Desktop> echo int_value | app.exe"
Note: int_value is the integer to be passed.

Now I had to invoke that command through windows form application i.e, from a GUI that takes int_value through text box and invoke the app.exe by a button.

I am not getting how to invoke the cmd to pass message using pipe through windows form app.

Any help will be appreciated.
