如何再次在类中调用"static void Main(string [] args)"

Question

我是C#的新手,现在正在研究控制台应用程序,我编写了以下代码:

Program.cs中

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

namespace Ch06Ex01
{
    class Program
    {
        static void Write()
        {
            Console.WriteLine("Please enter any string..!!");
        }

         static void Main(string[] args)
        {       

            Write();
            string name = Console.ReadLine();
            Write();
            string name1 = Console.ReadLine();
            Write();
            string name2 = Console.ReadLine();
            Write();
            string name3 = Console.ReadLine();

             Console.WriteLine("{0}, {1}, {2}, {3}",name,name1,name2,name3);

             Console.WriteLine("enter \"y\" to restart the program and \"n\" to exit the Program");
             string selectedOption = Console.ReadLine();

             if (selectedOption == "y")
             {
                 // howto call  static void Main(string[] args) here agin so that the program start itself from the start point

             }    

             //else if (selectedOption == "n")
            {
               //Terminate the Program
             }
             Console.ReadKey();
         }      

    }

}

现在到了这一点:

 if (selectedOption == "y")
             {
                 // howto call  static void Main(string[] args) here agin so that the program start itself from the start point

             }    

我想重新启动程序,如果用户输入"Y"并终止它,如果用户输入"N",对于所有我试图用goto语句像这个目的冷杉:

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

namespace Ch06Ex01
{
    class Program
    {
        static void Write()
        {
            Console.WriteLine("Please enter any string..!!");
        }

         static void Main(string[] args)
        {
            StartPoint;

            Write();
            string name = Console.ReadLine();
            Write();
            string name1 = Console.ReadLine();
            Write();
            string name2 = Console.ReadLine();
            Write();
            string name3 = Console.ReadLine();

             Console.WriteLine("{0}, {1}, {2}, {3}",name,name1,name2,name3);

             Console.WriteLine("enter \"y\" to restart the program and \"n\" to exit the Program");
             string selectedOption = Console.ReadLine();

             if (selectedOption == "y")
             {
                 // howto call  static void Main(string[] args) here agin so that the program start itself from the start point
                 goto StartPoint;
             }    

             //else if (selectedOption == "n")
             Console.ReadKey();
         }      

    }
}

但它对我没有用,StartPoint;它给出了错误

Only assignment, call, increment, decrement, await, and new object expressions can be used as a statement   C:\Users\Ahsan\Desktop\C# for Beginners Examples\Ch06Ex01\Ch06Ex01\Program.cs   18  13  Ch06Ex01

然后我试图在点上调用main函数本身

 if (selectedOption == "y")
         {
             // howto call  static void Main(string[] args) here agin so that the program start itself from the start point

         }    

但它在这里给我带来了很多错误,不知道现在该怎么做,任何人都可以帮助我吗？不知道该怎么做这个工作....再次在类中调用"static void Main(string [] args)"将是首选....

Answer 1

首先,您的标签不正确.标签的末尾应该有一个冒号字符:..所以你的标签应该是这样的:

StartPoint:

但是:

你应该循环直到满足条件.在这种情况下..条件是不重启:

bool running = true;

while (running) {
    /* 
     * all of your other code
     * should go here
     */
    if (selectedOption != "y") {
        running = false;
    }
}

Answer 2

你真的不应该使用goto或再次调用你的Main(递归),do while是一个更好的解决方案来重复你的逻辑多次:

    string selectedOption;
    do {
        Write();
        string name = Console.ReadLine();
        Write();
        string name1 = Console.ReadLine();
        Write();
        string name2 = Console.ReadLine();
        Write();
        string name3 = Console.ReadLine();

         Console.WriteLine("{0}, {1}, {2}, {3}",name,name1,name2,name3);

         Console.WriteLine("enter \"y\" to restart the program and \"n\" to exit the Program");
         selectedOption = Console.ReadLine();
      } while (selectedOption == "y")
      Console.ReadKey();
