持续输入至开关箱，直到我按下退出c#

我正在尝试创建一个程序，在按下选项“6”之前，应用程序不应退出。下面是我的示例程序：现在，如果我按下任何选项，它将执行相应的方法，执行完成后控制台窗口将关闭（退出应用程序）。我希望控制台等待输入下一个选项

Console.WriteLine(@"Select one of the following option:                                
                            1-Write Apps

                            3-Write OS
                            4-Write Packages
                            5-All the above
                            6-Exit");
           string strReadKey = Console.ReadKey().KeyChar.ToString();

           int.TryParse(strReadKey, out selectionKey);


           switch (selectionKey)
           {

               case 1:
                   DoApps(reqObj);
                   return;
               case 2:
                   DoDrivers(reqObj);
                   return;
               case 3:
                   DoOS(reqObj);
                   return;
               case 4:
                   DoPackages(reqObj);
                   return;
               case 5:
                   DoAll(reqObj);
                   return;
               case 6:
                   Environment.Exit(0);                       
                   return;
               default:
                   DoAll(reqObj);
                   return;
           }

您只需将代码放入循环中，然后将

return

语句更改为

break

语句：

while(true) // Loop forever
{
      string strReadKey = Console.ReadKey().KeyChar.ToString();
      int.TryParse(strReadKey, out selectionKey);


       switch (selectionKey)
       {

           case 1:
               DoApps(reqObj);
               break; // Break, don't return
           case 2:
               DoDrivers(reqObj);
               break;
           case 3:
               DoOS(reqObj);
               break;
           case 4:
               DoPackages(reqObj);
               break;
           case 5:
               DoAll(reqObj);
               break;
           case 6:
               Environment.Exit(0);                       
               break;
           default:
               DoAll(reqObj);
               break;
       }
}

如果希望在每次迭代中提示输入，也可以将提示移动到循环中。

如果希望在每次迭代中提示输入，也可以将提示移动到循环中。

只需将整个内容包装在while语句中即可

while (true)
{
     Console.WriteLine(@"Select one of the following option:

                            3-Write OS
                            4-Write Packages
                            5-All the above
                            6-Exit");
           string strReadKey = Console.ReadKey().KeyChar.ToString();

           int.TryParse(strReadKey, out selectionKey);


           switch (selectionKey)
           {

               case 1:
                   DoApps(reqObj);
                   break;
               case 2:
                   DoDrivers(reqObj);
                   break;
               case 3:
                   DoOS(reqObj);
                   break;
               case 4:
                   DoPackages(reqObj);
                   break;
               case 5:
                   DoAll(reqObj);
                   break;
               case 6:

用while语句来概括整个过程

                            5-All the above

           string strReadKey = Console.ReadKey().KeyChar.ToString();

           int.TryParse(strReadKey, out selectionKey);


           switch (selectionKey)

               case 1:

                   break;
               case 2:
                   DoDrivers(reqObj);
                   break;
               case 3:

首先，我要做的是把它变成一种方法：

public void AskForInput()
{
Console.WriteLine(@"Select one of the following options:                                
                        1-Write Apps 
                        2-Write Drivers
                        3-Write OS
                        4-Write Packages
                        5-All the above
                        6-Exit");
       string strReadKey = Console.ReadKey().KeyChar.ToString();
       int.TryParse(strReadKey, out selectionKey);
       switch (selectionKey)
       {
           case 1:
               DoApps(reqObj);
               return;
           case 2:
               DoDrivers(reqObj);
               return;
           case 3:
               DoOS(reqObj);
               return;
           case 4:
               DoPackages(reqObj);
               return;
           case 5:
               DoAll(reqObj);
               return;
           case 6:
               Environment.Exit(0);                       
               return;

然后像这样使用它：

里德，我试着给予，{true}{Case 1:DoApps（）；break；等等，}它一直在运行我的方法。它不会返回控制台进行下一步操作input@gogreen有道理。看看你怎么不提示输入？@gogreen试着在那里复制我的代码。每次通过while循环时，它都会对输入进行Prompts。里德和我得到了几乎完全相同的代码，只是我继续把输入例程放在那里。里德，我试着给出，{true}{Case 1:DoApps（）；break；等等。}它一直在运行我的方法。它不会返回控制台进行下一步操作input@gogreen有道理。看看你怎么不提示输入？@gogreen试着在那里复制我的代码。每次通过while循环时，它都会对输入进行Prompts。里德和我提出了几乎完全相同的代码，只是我继续把输入例程放在那里。
