int exitCode
)
public:
static void Exit (
int exitCode
)
public static void Exit (
int exitCode
)
public static function Exit (
exitCode : int
)

示例
下面的代码示例说明如何使用 Exit 方法终止程序执行并向操作系统返回退出代码。
' Example for the Environment.Exit( Integer ) method.
Imports System
Module ExitTest
Sub Main()
Console.WriteLine( _
"If this program is invoked with [{0}] " & _
"from the command prompt,", _
Environment.CommandLine)
Dim args As String() = Environment.GetCommandLineArgs()
' args[0] is the program name, and args[1] is the first argument.
' Test for a command-line argument.
If args.Length > 1 Then
' Parse the argument. If successful, exit with the parsed code.
Try
Dim exitCode As Integer = Integer.Parse(args(1))
Console.WriteLine("it exits with code: 0x{0:X8}.", exitCode)
Environment.Exit(exitCode)
' If the parse fails, you fall out of the program.
Catch
End Try
End If
Console.WriteLine("it exits by falling through.")
End Sub 'Main
End Module 'ExitTest
