Question

我有一个问题。我和我的朋友在一个程序代码上工作，但他使用bool函数true / false。我很困惑那一个。我想知道是否还有其他选择来获取输入以使代码更清晰。请为此提供解决方案感谢。

    static bool needToGetInputFromUser;
    static bool isUserEnteredValidInputData = false;

    static void Main(string[] args)
    {
        int Choice;

        do
        {
            needToGetInputFromUser = false;
            Console.WriteLine("Please select any of the following options to continue");
            Console.WriteLine("");

            Console.WriteLine("Press1: To Track Customer ");
            Console.WriteLine("Press2 : To track Supplier");
            Choice = Convert.ToInt16(Console.ReadLine());

            if (Choice == 1)
            {
                TrackCustomerData();

                Console.WriteLine("Would you like to track Supplier? (Y/N).");
                if (Convert.ToString(Console.ReadLine()).ToLower() == "y")
                {
                    TrackSupplierData();
                }
            }
            else if (Choice == 2)
            {
                TrackSupplierData();

                Console.WriteLine("Would you like to track customer? (Y/N).");
                if (Convert.ToString(Console.ReadLine()).ToLower() == "y")
                {
                    TrackCustomerData();
                }
            }
            else
            {
                Console.WriteLine("Please choose correct choice");
                Console.WriteLine("Would you like to re-enter choice? (Y/N).");

                if (Convert.ToString(Console.ReadLine()).ToLower() == "y")
                {
                    needToGetInputFromUser = true;
                }
            }
    } while (needToGetInputFromUser);

Answer 1

当涉及动态读取输入时，这将是最简单的一个。但是，您也可以使用Form（也是一种简单的方法）或WebPage来相应地读取和调用该方法。在这种情况下，您必须增加代码的复杂性。

步骤：

创建表单应用程序
在表单中，创建一个包含两个选项（客户和供应商）的下拉列表。
在表单中创建一个按钮，该按钮将根据下拉列表中的选定值调用方法。

Answer 2

只是一个想法

bool GetInput(){
  Console.WriteLine("");
 if( Convert.ToString(Console.ReadLine()).ToLower() == "y")
    return true;
 else 
    return false;
}

我不是一个控制台应用程序的人，任何人都可以编辑这个

do while是保持控制台重复直到获得所需输入的好方法。将以下代码复制到LinqPad中进行试用，并在不弄乱组代码的情况下进行调整。它以你想要的方式流动。

void Main()
{
    var needToGetInputFromUser = false;
    var isUserEnteredValidInputData = false;
    var choice = 0;

    do
    {
        needToGetInputFromUser = false;
        Console.WriteLine("Please select any of the following options to continue");
        Console.WriteLine();

        Console.WriteLine("Press 1 : To Track Customer ");
        Console.WriteLine("Press 2 : To track Supplier");

        //previous implementation could throw an exception and end program
        //use this for non integer inputs
        if (!int.TryParse(Console.ReadLine(), out choice))
        {
            needToGetInputFromUser = InvalidInput();
        }

        if (choice == 1)
        {
            TrackCustomerData();

            Console.WriteLine("Would you like to track Supplier? (Y/N).");
            if (Convert.ToString(Console.ReadLine()).ToLower() == "y")
            {
                TrackSupplierData();
            }
        }
        else if (choice == 2)
        {
            TrackSupplierData();

            Console.WriteLine("Would you like to track Customer? (Y/N).");
            if (Convert.ToString(Console.ReadLine()).ToLower() == "y")
            {
                TrackCustomerData();
            }
        }
        else
        {
            //Integers that are not 1 or 2
            needToGetInputFromUser = InvalidInput();
        }
    } while (needToGetInputFromUser);
}

public bool InvalidInput()
{
    Console.WriteLine("Please choose correct choice");
    Console.WriteLine("Would you like to re-enter choice? (Y/N).");

    if (Convert.ToString(Console.ReadLine()).ToLower() == "y")
    {
        return true;
    }
    return false;
}

public void TrackCustomerData()
{
    //Some customer data work
    Console.WriteLine("Customer tracked...");
}

public void TrackSupplierData()
{
    //come supllier data work
    Console.WriteLine("Supplier tracked...");
}

任何替代方法来获取输入而不是使用bool
