1.安装jmail4.3
2.找到jmail.dll 引用到项目中。
using jmail;
....................
jmail.Message Jmail = new jmail.Message();
DateTime t = DateTime.Now;
String Subject = "haohao 学习 天天向上";
String body = "你好 《》<br><b>科学</b>12:15";
String FromEmail = "escdns@gmail.com";
String ToEmail = "woolern@sohu.com";
//Silent属性:如果设置为true,JMail不会抛出例外错误. JMail. Send( () 会根据操作结果返回true或false
Jmail.Silent = true;
//Jmail创建的日志,前提loging属性设置为true
Jmail.Logging = true;
//字符集,缺省为"US-ASCII"
Jmail.Charset = "GB2312";
//信件的contentype. 缺省是"text/plain") : 字符串如果你以HTML格式发送邮件, 改为"text/html"即可。
//Jmail.ContentType = "Multipart/Mixed";
//添加收件人(若几个收件人就添加几行下面的代码)
Jmail.AddRecipient(ToEmail, "", "");
//Jmail.AddRecipientCC,Jmail.AddRecipientBCC (抄送,密送,用法同Jmail.AddRecipient)

//发件人邮件用户名

Jmail.MailServerPassWord = "********";
//设置邮件标题
Jmail.Subject = Subject;
//邮件添加附件,(多附件的话,可以再加一条Jmail.AddAttachment( "c:\\test.jpg",true,null);)就可以搞定了。
//[注]:加了附件,讲把上面的Jmail.ContentType="text/html";删掉。否则会在邮件里出现乱码。
Jmail.AddAttachment("c:\\img200610311000250.jpg", true, null);
//邮件内容,(若为纯文本就改为Jmail.Body )
Jmail.HTMLBody = body;
//Jmail发送的方法
Jmail.Send("smtp.sina.net", false);
Jmail.Close();
