試圖運行我的代碼和編譯器似乎只是關閉後，它執行

Question

我想運行一個程序和編譯器似乎只是在執行後崩潰......我沒有生成錯誤。

我試過註釋掉代碼塊，但仍無濟於事。我已經將主複製到另一個文件並運行它，它的工作....所以我真的難住。

using System; 
using System.Collections.Generic; 
using System.Linq; 
using System.Text; 
using System.Threading.Tasks; 
namespace ConsoleApplication1 
{ 
    public class Student 
{ 

string Fname, Lname, Program ; 
int Sid ; 

// Inputting information for students 
public void InputStudentInfo() 
{ 
    Console.WriteLine ("Please enter your first name") ; 
    Fname = Console.ReadLine() ; 
    Console.WriteLine ("Please enter you last name") ; 
    Lname = Console.ReadLine() ; 
    Console.WriteLine ("Please enter you student ID#") ; 
    Sid = int.Parse(Console.ReadLine()) ; 
    Console.WriteLine ("Enter the Program that you are completeing") ; 
    Program = Console.ReadLine() ; 
} 

// Printing information for students 
public void PrintStudentInfo() 
{ 
    Console.Write (" Your name is " + Fname) ; 
    Console.Write(" " + Lname); 
    Console.WriteLine (" Your student identification number is " + Sid) ; 
    Console.WriteLine (" The program you are registered for is " + Program) ; 
}

    } 

    public string coname 
    { 
     get

      return coursename ; 
     } 
     set

      coursename = value ;

     for (int i = 0; i < 3; i++) 
     {

      grade.finalper[i] = (grade.midexam[i] + grade.finalegrade[i])/2; 
      grade.totalgrade[i] = (grade.courseper[i] + finalper[i])/2; 
     } 
    }

      Console.Writeline (" Your homework grade is" + grade.hwgrade[i]) ; 
      // .....

    } 
     static void Main(string[] args) 
     { 
      int accode ; 
      Student student = new Student() ; 
      Course course = new Course() ; 
      Grade grade = new Grade() ; 
      do 
      { 
       Console.WriteLine(" 1. Input Student information"); 
       Console.WriteLine(" 2. Input Course information"); 
       Console.WriteLine(" 3. Input Grade information"); 
       Console.WriteLine(" 4. Print Course information"); 
       Console.WriteLine(" 5. Print Student information"); 
       Console.WriteLine(" 6. Print Grade information"); 
       Console.WriteLine(" 7. Print Student information including Course they are registered in and the grade obtained for that course"); 
       Console.WriteLine(" 8. Print grade info of the course in which student has achieved the highest grade"); 
       Console.WriteLine(" 0. Exit"); 
       Console.WriteLine(" Please select a choice from 0-8"); 
       accode = Console.ReadLine(); 
       switch (accode) 
       { 
        case 1: 
         student.InputStudentInfo(); 
         break; 
        case 2: 
         course.InputCourseInfo(); 
         break; 
        case 3: 
         grade.InputGradeInfo(); 
         break; 
        case 4: 
         course.PrintCourseInfo(); 
         break; 
        case 5: 
         student.PRintStudentInfo(); 
         break; 
        case 6: 
         grade.PrintGradeInfo(); 
         break; 
        case 0: 
         Console.WriteLine(" You have chosen to exit the program have a good day. =)"); 
         break; 
       } 
      } while (accode != 0); 
      Console.ReadKey(); 
     } 
    } 
} 

時，我說，我複製了主......我的意思是我把所有的代碼，這是在主，打開一個新的項目，放在後面的代碼，程序運行起來的條款。我嘗試了關於使用try和catch的建議......但同樣的問題仍然會發生，當我按start時，沒有錯誤，cmd會在瞬間打開和關閉。當我按Ctrl + F5屏幕出現，但只說'按任意鍵繼續'。

把一個嘗試捕捉你的主要方法，這樣給你一個提示，什麼是錯的：

static void Main(string[] args) 
      { 
    try 
    { 
       int accode ; 
       Student student = new Student() ; 
       Course course = new Course() ; 
       Grade grade = new Grade() ; 
       do 
       { 
        Console.WriteLine(" 1. Input Student information"); 
... 
        Console.WriteLine(" 0. Exit"); 
        Console.WriteLine(" Please select a choice from 0-8"); 
        accode = Console.ReadLine(); 
        switch (accode) 
        { 
    ... 
        } 
       } while (accode != 0); 
    } 
    catch (Exception Ex) 
    { 
     Console.Writeline("Exception: " + ex.Message); 
    } 
       Console.ReadKey(); 
      }
