                Console.WriteLine("General Exception: " + ex.Message);
            }
        }

2.使用实例

        private void button1_Click(object sender, EventArgs e)
        {
        SendEmail("135791@qq.com", "邮件主题", "邮件正文内容","smtp.qq.com", 587, true,"C:\\Users\\75252\\Desktop\\2024Test\\Source.bmp",false,new string[2]{"111111@qq.com","2222222@gmail.com"});
        }
