Gets or sets the exit code of the process.
Assembly: mscorlib (in mscorlib.dll)
If the Main method returns void, you can use this property to set the exit code that will be returned to the calling environment. If Main does not return void, this property is ignored. The initial value of this property is zero.
The property is a signed 32-bit integer. To prevent the property from returning a negative exit code, you should not use values greater than or equal to 0x80000000.
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.
The following example displays its own exit code.
Windows 8, Windows Server 2012, Windows 7, Windows Vista SP2, Windows Server 2008 (Server Core Role not supported), Windows Server 2008 R2 (Server Core Role supported with SP1 or later; Itanium not supported)
