如何調用「靜態無效的主要（字串[] args）」中的類再次

Question

我在C＃中新的控制檯應用程序的工作現在是一個天我寫了下面的代碼：

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(); 
     }  

    } 

}

現在在點：

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

      }  

我想重新啓動程序，如果用戶輸入「Y」並終止它，如果用戶輸入「N」，所有這一切的目的冷杉我試圖用像goto語句：

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(); 
     }  

    } 
} 

但事與願違在StartPoint;工作對我來說它給出錯誤

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 

然後我試着打電話給主函數本身在點

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

     }  

，但在這裏給了我很多的錯誤，不要懂得d現在呢，任何人都可以幫助我嗎？不知道如何做這個事情.... 調用「靜態無效主（字符串[] ARGS）」在該班再次將首選....

Answer 1

再打電話的方法，通過在相同的論點，凡在最初過去了，也try to avoid using goto if you can：

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

Answer 2

首先，你的標籤是不正確的。標籤的結束應該有一個冒號: ..所以你的標籤應該一直這樣：

StartPoint: 

然而：

你應該只循環，直到滿足條件。在這種情況下..條件是要不要重啓：

bool running = true; 

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

Answer 3

你真的不應該使用goto語句或致電主再次（遞歸），而做一個更好的解決方案來重複你的邏輯muliple時間：

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(); 

Answer 4

是這樣的：

static void Main(string[] args) 
      {  
       string selectedOption = ""; 

       do 
       { 

           ........... 

       } 
       while (selectedOption == "y") 

       if (selectedOption == "n") 
       { 
        //Terminate the Program 
        } 

      }

嘗試把您將在另一種方法的主類之外執行像

void execute() 
{ 
     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(); 

} 

然後在代碼的主要

static void Main(string[] args) 
{ 
    bool run = true 
    while(run){ 
     execute() 
     Console.WriteLine("enter \"y\" to restart the program and \"n\" to exit the Program"); 
     selectedOption = Console.ReadLine(); 
     if (selectedOption == "n") 
     { 
      run = false; 
     }  
    } 
}
