System Windows Forms Application Exit   - Informs all message pumps that they must terminate  and then closes all application windows after the messages have been processed   This method stops all running message loops on all threads and closes all windows of the application  This method does not force the application to exit  The Exit   method is typically called from within a message loop  and forces Run   to return  To exit a message loop for the current thread only  call ExitThread     This is the call to use if you are running a Windows Forms application   As a general guideline  use this call if you have called System Windows Forms Application Run     System Environment Exit exitCode  - Terminates this process and gives the underlying operating system the specified exit code   This call requires that you have SecurityPermissionFlag UnmanagedCode permissions  If you do not  a SecurityException error occurs   This is the call to use if you are running a console application   I hope it is best to use Application Exit  See also these links    Application Exit   vs Application ExitThread   vs Environment Exit    http   geekswithblogs net mtreadwell archive 2004 06 06 6123 aspx

Application Exit is for Windows Forms applications - it informs all message pumps that they should terminate  waits for them to finish processing events and then terminates the application   Note that it doesn t necessarily force the application to exit    Environment Exit is applicable for all Windows applications  however it is mainly intended for use in console applications   It immediately terminates the process with the given exit code   In general you should use Application Exit in Windows Forms applications and Environment Exit in console applications   although I prefer to let the Main method   entry point run to completion rather than call Environment Exit in console applications    For more detail see the MSDN documentation

What role do they play when exiting an application in C     The same as every other application  Basically they get returned to the caller  Irrelvant if ythe start was an iicon double click  Relevant is the call is a batch file that decides whether the app worked on the return code  SO  unless you write a program that needs this  the return dcode IS irrelevant      But what is the difference    One comes from environment one from the System Windows Forms  Application  Functionall there should not bbe a lot of difference
