How to loop a Console App
提问by jay_t55
i just need to be able to loop a console app. what i mean by that is:
我只需要能够循环控制台应用程序。我的意思是：
program start:
display text
get input
do calculation
display result
display text
get input.
REPEAT PROCESS INFINATE NUMBER OF TIMES UNTIL THE USER EXITS THE APPLICATION.
program end.
i hope that made sense. can anyone please explain how i would go about doing this? thank you :)
我希望这是有道理的。任何人都可以请解释我将如何去做吗？谢谢你 ：）

You could wrap the whole body of your Main method in program.cs in a while loop with a condition that will always be satisfied.
您可以在 while 循环中将 program.cs 中的 Main 方法的整个主体包装起来，并始终满足条件。
E.g (in pseudo-code)
例如（在伪代码中）
While (true)
{
Body
}

while(true) {
DisplayText();
GetInput();
DoCalculation();
DisplayResult();
DisplayText();
GetInput();
}
The user can stop the program at any point with CTRL-C.
用户可以随时使用 停止程序CTRL-C。
Is this what you meant?

You can just put a loop around whatever you're doing in your program.
您可以围绕您在程序中所做的任何事情进行循环。

Use a While loop
使用 While 循环
bool userWantsToExit = false;
get input
while(!userWantsToExit)
{
do calc;
display results;
display text;
get input;
if (input == "exit")
userWantsToExit = true;
}
program end;
回答by Traveling Tech Guy
Console.WriteLine("bla bla - enter xx to exit");
string line;
while((line = Console.ReadLine()) != "xx")
{
string result = DoSomethingWithThis(line);
Console.WriteLine(result);
}
