Question

在Messages类中有一个名为questionWhatisYourName()的方法，此方法由另一个名为questionSurname()的方法调用，此方法由类程序的主方法调用。是否可以将数据从questionWhatisYourName()返回到questionSurname()而不在消息类中调用它？也许我应该将它作为questionSurname()方法的参数传递？

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ConsoleApplication1
{
class TextEffects
{
    public void drawLine() {
        Console.WriteLine("------------------------------------");
    }
    public void drawLine(String linetype)
    {
        Console.WriteLine(linetype +
        linetype + linetype + linetype + linetype + linetype + linetype + linetype + linetype + linetype
        + linetype + linetype + linetype + linetype + linetype + linetype + linetype + linetype);
    }

}
class Messages
{
    public void hello()
    {
        Console.WriteLine("Hello and welcome.");
    }
    public String questionWhatIsYourName()
    {
        Console.WriteLine("What is your name?");
        String name = Console.ReadLine();
        return name;
    }
    public void questionSurname()
    {
        String myname = this.questionWhatIsYourName();
        Console.WriteLine(myname + " what is your surname?");

    }
}
class Program
{
    static void Main(string[] args)
    {
        TextEffects texteffects = new TextEffects();
        Messages messages = new Messages();
        texteffects.drawLine("+");
        messages.hello();
        messages.questionSurname();
    }
}
}

Answer 1

是的，将其作为字符串参数传递。

public void questionSurname(string myname)
{
    // ...
}

这样称呼：

string name = messages.questionWhatIsYourName();
messages.questionSurname(name);

只需将Name添加到类Propeties并使用它：

 class Messages
 {
     private string myName;
     public void Hello()
     {
         Console.WriteLine("Hello and welcome.");
     }
     public void QuestionWhatIsYourName()
     {
        Console.WriteLine("What is your name?");
        myName = Console.ReadLine();            
     }
     public void QuestionSurname()
     {
         QuestionWhatIsYourName();
         Console.WriteLine(myname + " what is your surname?");
     } 
}

请注意，您的代码不是标准。方法应该从uppper案例开始并且类消息的名称只是没有描述该类负责的内容。
