Terminates this process and gives the underlying operating system the specified exit code.
Assembly: mscorlib (in mscorlib.dll)
[SecurityPermissionAttribute(SecurityAction.Demand, Flags = SecurityPermissionFlag.UnmanagedCode)] public static void Exit( int exitCode )
- Type: System.Int32
Exit code to be given to the operating system. Use 0 (zero) to indicate that the process completed successfully.
The caller does not have sufficient security permission to perform this function.
For the exitCode parameter, use a non-zero number to indicate an error. In your application, you can define your own error codes in an enumeration, and return the appropriate error code based on the scenario. For example, return a value of 1 to indicate that the required file is not present and a value of 2 to indicate that the file is in the wrong format. For a list of exit codes used by the Windows operating system, see System Error Codes in the Windows documentation.
Calling the method differs from using your programming language's return statement in the following ways:
always terminates an application. Using the return statement may terminate an application only if it is used in the application entry point, such as in the Main method.
terminates an application immediately, even if other threads are running. If the return statement is called in the application entry point, it causes an application to terminate only after all foreground threads have terminated.
requires the caller to have permission to call unmanaged code. The return statement does not.
If is called from a try or finally block, the code in any catch block does not execute. If the return statement is used, the code in the catch block does execute.
