c# 连接数据库时 数据库的打开问题

Question

     try
            {
                using (SqlConnection conn = new SqlConnection(@"Data Source = ./SQLEXPRESS;AttachDBFilename = G:\传智播客\ADO.NET\第一个mdf\Database1.mdf;Integrated Security = True; User Instance = True"))
                {
                    conn.Open();
                    using (SqlCommand cmd = conn.CreateCommand())
                    {
                        cmd.CommandText = "insert into MyTable1(Name) values('abc')";
                        cmd.ExecuteNonQuery();
                        Console.WriteLine("插入成功!");
                    }
                }
            }
            catch (Exception e)
            {                Console.WriteLine(e.Message);
            }
            Console.WriteLine("打开数据库连接成功");我的程序运行到conn.open()就不往下执行了,这是为什么啊??

Answer 1

1.设置数据库连接的超时时间，conn.ConnectionTimeout=30;
2.断点调试
