C＃如何将未知值变量（用户输入）传递给返回方法-英雄云拓展知识分享

早上好/下午，

我很乐意经过参考和价值进行一些澄清。如果我将变量值设置为“ 0”，但在用户输入以后不会覆盖，则发布的程序可行之有效的。因此，这种情况下，我相信这个问题是经过的，但是我的教授说，该计划的一切都应当是静态的。

简称：如何在不使用void的情形下传递输入变量？

我很新。这只是第3章，因此任何帮助都会很棒。

namespace Lesson3
{
class Program
{
public static void Main(string[] args)
{
// declarations
// 12 inches to a foot
// 36 inches to a yard
// 63360 inches per 1 mile
double userInput= 0; // if "0" is removed the program will not function CS0165 error
double feet = 12;
double yards = 36;
double miles = 63360;
double ansFeet = userDivFeet(ref feet, ref userInput);
double ansYards = userDivYards(ref yards, ref userInput);
double ansMiles = userDivMiles(ref miles, ref userInput);
Console.WriteLine("Please enter the number of inches to convert: ");
userInput = Convert.ToInt32(Console.ReadLine());
// output each calculation and display with console to hold the results
WriteLine(userInput + " inches converts into " + ansFeet + " feet.");
WriteLine(userInput + " inches converts into " + ansYards + " yards.");
WriteLine(userInput + " inches converts into " + ansMiles + " miles.");
Console.ReadKey();
}
public static double userDivFeet(ref double userInput, ref double feet)
{
return userInput / feet;
}
public static double userDivYards(ref double userInput, ref double yards)
{
return userInput / yards;
}
public static double userDivMiles(ref double userInput, ref double miles)
{
return userInput / miles;
}
}

}
