在项目里新建一个email.aspx页面。在email里拖入三个文本框,分别命名为:tbTo、tbSubject、tbBody,它们分别是用做:收件人、Email的主题、Email的内容。然后再加入一个按钮。
双击按钮,在email.aspx.cs页面里,添加“using System.Web.Mail;”的引用。
再在Page_Load事件里加入以下代码:
if (!this.IsPostBack)
{}
然后在Button1_Click事件里加入以下代码:
MailMessage myMail = new MailMessage();
myMail.Subject = this.tbSubject.Text.Trim();
myMail.From = [email protected];
myMail.To = this.tbTo.Text.Trim();
myMail.Body = this.tbBody.Text;
SmtpMail.SmtpServer = "smtp服务器的地址";
SmtpMail.Send(myMail);
Response.Write("发送成功");
只要把SmtpMail.SmtpServer换成您的smtp服务器名或IP就可以了。编译看看运行结果吧。
完整的代码如下:
