求解答！为什么用ADO.NET连接数据库并创建数据表结果是这样的呢？

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

namespace AdoNetConsoleApplication
{
    class Program
    {
        static void Main(string[] args)
        {
            new Program().CreateTable();
        }
        public void CreateTable()
        {
            SqlConnection con = null;
            try
            {
                // Creating Connection  
                con = new SqlConnection("database=aya; integrated security=SSPI");
                // writing sql query  
                SqlCommand cm = new SqlCommand("create table student_info(id int not null,name varchar(100), email varchar(50), join_date date)", con);
                // Opening Connection  
                con.Open();
                // Executing the SQL query  
                cm.ExecuteNonQuery();
                // Displaying a message  
                Console.WriteLine("Table created Successfully");
            }
            catch (Exception e)
            {
                Console.WriteLine("OOPs, something went wrong." + e);
            }
            // Closing the connection  
            finally
            {
                con.Close();
            }
        }
    }
}

这个样子之后窗口就关闭了！这是什么原因呢？求解答？

你没有停啊 肯定就走完了
你是想看打印的东西 ，加一句 Console.ReadKey();
