How to close a console application by typing EXIT?
提问by Rajdeep
I have an VB.Net Console Application running and I do not want it to close when the user hit the ENTERbutton, rather I want it to close when they type EXITand then press ENTER. What should I do?
我有一个 VB.Net 控制台应用程序正在运行，我不希望它在用户点击ENTER按钮时关闭，而是希望它在他们键入EXIT然后按时关闭ENTER。我该怎么办？

Read from the console using Console.ReadLine()(which requires a carriage return to complete).
使用Console.ReadLine()从控制台读取（需要回车才能完成）。
If (Console.ReadLine() = "EXIT") Then
Environment.Exit(0) 'or, simply return from the Main method
End If
Another way to phrase it:
另一种表达方式：
While (Not Console.ReadLine() = "EXIT")
Console.WriteLine("Didn't say the magic word!")
End While
Remember that once you return from your Mainmethod, your console application closes. It's hard to advise you exactly what to do without seeing the logical structure of your application, but remember: if you want to prevent your application from exiting, don't let your Mainmethod return.
请记住，一旦您从您的Main方法返回，您的控制台应用程序就会关闭。如果不查看应用程序的逻辑结构，很难准确地建议您做什么，但请记住：如果您想阻止应用程序退出，请不要让您的Main方法返回。
