我正在尝试运行一个程序，编译器在执行后似乎只是崩溃...我没有构建错误。
我试过评论代码块但仍然无济于事。我已经将主要文件复制到另一个文件中并运行它并且它起作用....所以我真的很难过。

就我什么时候说我复制了主...我的意思是我把主要的所有代码都打开了，然后打开了一个新项目并放回了代码，程序运行了。我尝试了关于使用try和catch的建议......但仍然会出现同样的问题，当我按下开始时，没有错误，cmd打开并在瞬间关闭。当我按ctrl + f5时屏幕出现但只显示'按任意键继续'。
答案 0 :(得分：3)
在你的main方法中加一个try catch来给你一个关于错误的提示：
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();
}
