Question

我刚开始研究C＃。并遇到了一个问题：当我在 Main 方法中使用Console.WriteLine时，它可以正常工作。但是，当我尝试将代码分解为方法时，WriteLine不会返回任何内容。（我使用Visual Studio来构建和编译项目）。

任务是找到一个人在按月资本化存款时可以获得的最终金额。我有点怀疑我只是搞砸了一些微不足道的事情，但仍然会欣赏一个解释:)谢谢

没有方法的代码：

using System;

class Program
{
    static void Main()
    {
        //User input
        Console.WriteLine("Enter the initial amount, percentage, and deposit time (months)");
        string userInput = Console.ReadLine();

        //Separating the input string into substrings
        string[] separated = userInput.Split(' ');

        //Getting the main variables
        double sum1 = double.Parse(separated[0]);
        double oneMonthPercentage = double.Parse(separated[1]) / 1200; //find a montly amount in percent = amount / 12 month / 100 
        double months = double.Parse(separated[2]);
        double initialSum = sum1;


        //Calculation of the final ammount
        for (int i = 1; i <= months; i++)
        {
            sum1 += sum1 * oneMonthPercentage;
        }

        //Output
        Console.WriteLine("Ammount: " + initialSum);
        Console.WriteLine("Percentage: " + oneMonthPercentage * 1200 + "%");
        Console.WriteLine("Time: " + months);
        Console.WriteLine("Final amount: " + Math.Round(sum1, 2));

    }
}

输出 - no_methods

带方法的代码（WriteLine不起作用）：

using System;

class Program
{ 
    static void Main()
    {
        //User input
        Console.WriteLine("Enter the initial amount, percentage, and deposit time (months)");
        string userInput = Console.ReadLine();
    }

    //Separating string into substrings
    public static string[] SeparateString(string userInput)
    {
        string[] separated = userInput.Split(' ');
        return separated;
    }

    //calculating the final amount at the end of deposit time
    public static double Calculate(string userInput)
    {

        // defining main variables for calculation

        double sum1 = double.Parse(SeparateString(userInput)[0]);
        double oneMonthPercentage = double.Parse(SeparateString(userInput)[1]) / 1200;
        double months = double.Parse(SeparateString(userInput)[2]);
        double initialSum = sum1;

        //calculation as to the formula 
        for (int i = 1; i <= months; i++)
        {
            sum1 += sum1 * oneMonthPercentage;
        }

        //Output
        Console.WriteLine("Ammount: " + initialSum);
        Console.WriteLine("Percentage: " + oneMonthPercentage * 1200 + "%");
        Console.WriteLine("Time: " + months);
        Console.WriteLine("Final amount: " + Math.Round(sum1, 2));

        return sum1;
    }
}

输出 - with_methods

Answer 1

您需要调用这些方法才能使它们正常工作。现在你只调用初始的WriteLine和ReadLine

Answer 2

您不会调用任何方法。你应该调用Calculate()方法：

static void Main()
{
    //User input
    Console.WriteLine("Enter the initial amount, percentage, and deposit time (months)");
    string userInput = Console.ReadLine();
    var result = Calculate(userInput); // call here
}

不从方法调用C＃Console.WriteLine
