C# 将用户信息存储到阵列以用于交换机状态

我的任务是菜单中的选项，目前我一直在尝试将用户输入（在本例中是带有t恤品牌和大小的字符串）存储到一个数组中，以便稍后在其他一些菜单选项中使用

namespace A4pf
{
    class Program
    {
        static void Main(string[] args)
        {
            int option = 0;

            Console.WriteLine("1. Add New T-shirt Details");
            Console.WriteLine("2. Edit Exisiting T-shirt detials");
            Console.WriteLine("3. Display All T-shirts in store");
            Console.WriteLine("4. Delete T-shirt information");
            Console.WriteLine("5. Exit");

            switch(option)
            {
                case 1:
                    Console.WriteLine("Please enter the T-Shirts Details. ");
                    Console.Write("Brand Name and size(eg. Thrasher-M");
                    string[] tshirtDetails = new string[12];

                    for (int i = 0; i < tshirtDetails.Length; i++)
                    {
                        tshirtDetails[i] = Console.ReadLine();
                    }
                    
                    break;
                default:
                    
                    break;
                  
            }
            Console.ReadLine();

您正在开关案例1中创建一个数组，因此每次输入案例1时，都会创建新的数组，从而删除以前的数据。我建议您尝试将该行移到

int option=0

上方，以便数组中的当前数据在其他案例中也可用，或者至少移动如果您想在输入案例1时删除以前的数据，请在开关案例外部设置数组。

正如其他人所说，您的数组范围太窄（太小）

假设你和4个人住在一起。你们每个人都有自己的房间，大家共享一个共同的空间——厨房。厨房里有一个冰箱，里面装着食物。你们都不允许进入彼此的房间。室友1决定冰箱放在他的房间里。现在没有其他人可以接触到冰箱里的食物rator，因为其他室友不允许进入他的房间。本质上，当你将数组声明放在case#1中时，就会发生这种情况。每个室友都需要在一个公共的地方——厨房。当你使用“{”和“}”以及诸如“if”、“For”、“switch case”等语句时，等等。您正在定义一个范围（即：一个房间）。最好只提供所需的访问权限，但同时确保需要访问变量（如数组）的所有内容都可以访问它

你是否被介绍/教过编写伪代码？写下你需要做的步骤。在适当的时候使用普通单词和C#语法——在编写伪代码时，使用正确的C#语法是不必要的，但有时是有帮助的。最初，从高级开始。然后修改它，直到你将这些步骤分解得足够多，你可以你可以决定细节是什么，需要多少细节

string[] tshirtDetails = new string[1];

下面是一个伪代码示例：

}

查看了5个选项后，我注意到我将向用户询问更多信息（t恤衫详细信息）。我将如何存储t恤衫详细信息？我将它们存储在字符串变量中。我需要存储多件t恤衫的详细信息。什么数据类型允许我存储多个值？我将使用一个数组--一个字符串数组。5个选项中有多少需要访问t恤细节？不止一个，因此我将确保它们都可以访问此数组。用户将输入多少t恤细节？我不确定--用户可以输入他/她想要的数量。我将从1开始，并调整大小根据需要设置数组

string[] tshirtDetails = new string[1];

让我们继续添加更多细节。我们将从为选项1添加更多细节开始

我需要了解t恤衫的详细信息。我如何才能让用户知道这一点

if userResponse = 1 then add new t-shirt details
{
    prompt user for t-shirt details (Console.WriteLine)     
    get t-shirt details from user (Console.ReadLine)
    store t-shirt details in array (tshirtDetails) 
}

让我们继续选项#2。我需要让用户编辑现有的t恤细节。他/她如何知道存在哪些t恤？选择此选项时我应该显示t恤细节，还是用户应该在选择此选项之前显示现有t恤？用户可以使用选项#3显示现有的t恤信息（如果不存在）他被解雇了

else if userResponse = 2 then edit existing t-shirt details
{
    prompt user for which t-shirt details to modify (Console.WriteLine)     
    get t-shirt index from user (Console.ReadLine)
    update t-shirt details in array (tshirtDetails) 
}

接下来，我们将为选项#3添加更多细节。由于我们使用的是数组，因此必须从变量中获取多个值。我们将使用循环。“for”（或“foreach”）应该可以工作

else if userResponse = 3 then display all t-shirts in store
{
   for each detail in tshirtDetails Console.WriteLine
}

转到选项4。我需要删除哪些t恤细节？我需要询问用户

else if userResponse = 4 then delete t-shirt information
{
    prompt user for which t-shirt details to modify (Console.WriteLine)     
    get t-shirt index from user (Console.ReadLine)
    remove t-shirt details from array (tshirtDetails)     
}

选项#5。这一个是不言自明的，所以我不需要在这里添加更多细节

else if userResponse = 5 then exit the program

若用户输入了一个无效的选项怎么办？我会通知他们，然后重新提示输入一个有效的选项

else 
    inform user of invalid option (Console.WriteLine)

修订版#3:

“在数组中存储t恤细节”。我的数组大小为1，如果用户输入三件t恤的细节会发生什么情况？在将每个t恤细节添加到数组中之前，我最好调整数组的大小。让我们在“在数组中存储t恤细节（tshirtDetails）”之前为选项#1添加一些伪代码

我们继续查看伪代码：

else if userResponse = 2 then edit existing t-shirt details
{
    prompt user for which t-shirt details to modify (Console.WriteLine)     
    get t-shirt index from user (Console.ReadLine)
    update t-shirt details in array (tshirtDetails) 
}

else if userResponse = 3 then display all t-shirts in store

   for each detail in tshirtDetails Console.WriteLine
}

else if userResponse = 4 then delete t-shirt information
{
    prompt user for which t-shirt details to modify (Console.WriteLine)     
    get t-shirt index from user (Console.ReadLine)
    remove t-shirt details from array (tshirtDetails)     
}

else if userResponse = 5 then exit the program

else 
    inform user of invalid option (Console.WriteLine)

我想我应该使用“switch case”语句而不是“if-else-if-else”语句

                        Console.WriteLine("\nT-shirt details deleted.\n");

                        break;

                    //    break;
                    default:

                        Console.WriteLine("\nError: Invalid option entered (" + optionStr + "). Please try again.\n");
                        break;
                }

                

            } while (option != 5);
        }
