第一步:首先新建一个页面register页面,在该页面的前台添加上用户名、密码、邮箱地址和三个文本框以及注册按钮。
第二步:在register页面的register.aspx.cs页面加上以下代码:
public void sendMail(string email, string activeCode,int number) {
MailMessage msg = new MailMessage(); msg.From = new MailAddress("q******09@126.com");填写一个126的邮箱 msg.To.Add(email); msg.Subject = "请激活注册";
StringBuilder contentBuilder = new StringBuilder(); contentBuilder.Append("请单击以下连接完成激活!"); contentBuilder.Append("<a href='http://localhost:8899/CheckActiveCode.aspx?activecode="+activeCode+"&id="+number+"'>激活</a>");
msg.Body = contentBuilder.ToString();
msg.IsBodyHtml = true;
SmtpClient client = new SmtpClient(); client.Host = "smtp.126.com";//发件方服务器地址 client.Port = 25;//发件方端口
NetworkCredential credetial = new NetworkCredential(); credetial.UserName = "qzc900809"; credetial.Password = "900809";
client.Credentials = credetial;//把证书交给代理。
client.Send(msg);/发送邮件 }
第三步:在注册按钮的单击事件中加上以下代码:
protected void Button1_Click(object sender, EventArgs e) { string userName = this.TextBox1.Text; string password = this.TextBox2.Text; string email = this.TextBox3.Text; string activeCode = Guid.NewGuid().ToString().Substring(0, 8);//生成激活码
string conStr = ConfigurationManager.ConnectionStrings["conStr"].ConnectionString;//在web.Confing中设置连接数据库字符串 int number; using (SqlConnection con = new SqlConnection(conStr)) { string sql = "insert into email (UserName,Password,Email,Active,ActiveCode) values(@username,@password,@email,@active,@activecode)"; SqlParameter[] prams = new SqlParameter[] { new SqlParameter("@username",userName), new SqlParameter("@password",password), new SqlParameter("@email",email), new SqlParameter("@active",false),/这个是查看是否激活 new SqlParameter("@activecode",activeCode)///激活码 }; using (SqlCommand cmd = new SqlCommand(sql, con)) { con.Open(); cmd.Parameters.AddRange(prams); number = cmd.ExecuteNonQuery(); } } if (number > 0) { sendMail(email, activeCode); //sendMail(string email,string activeCode,int id);//给注册用户发邮件
Response.Redirect("regionMessage.aspx");///这个可有可无,只是一个提示成功的页面 } else { Response.Write("注册失败,请重新注册!"); } }
第四步:再重新新建一个CheckActiveCode.aspx页面,然后再该页面(CheckActiveCode.aspx.cs)的Page_Load中
加上以下代码:
//1取出参数id int id = Convert.ToInt32(Request["zcid"]); string activeCode = Request["activecode"].ToString();
//2判断id为id的记录是否存在。 //连接数据库 string conStr = ConfigurationManager.ConnectionStrings["connStr"].ConnectionString; int number; using (SqlConnection con = new SqlConnection(conStr)) { string sql = "select count(*) from Registor where zcid=@id"; using (SqlCommand cmd=new SqlCommand(sql,con)) { con.Open(); cmd.Parameters.AddWithValue("@id",id); number=Convert.ToInt32(cmd.ExecuteScalar()); } } if (number > 0) { //如果该用户存在取出其ActiveCode字段进行比较。如果一样。把Ative字段修改为true
//连接数据库
string AC; using (SqlConnection con = new SqlConnection(conStr)) { string sql = "select ActiveCode from Registor where zcid=@id"; using (SqlCommand cmd = new SqlCommand(sql, con)) { con.Open(); cmd.Parameters.AddWithValue("@id", id); AC=cmd.ExecuteScalar().ToString();//wrong?
}
} if (activeCode == AC) { Response.Write("激活成功!"); using (SqlConnection con = new SqlConnection(conStr)) { string sql = "update Registor set Active=1 where zcid=@id"; using (SqlCommand cmd = new SqlCommand(sql, con)) { con.Open(); cmd.Parameters.AddWithValue("@id", id); number = Convert.ToInt32(cmd.ExecuteScalar());
}
}
} else { Response.Write("用户已存在,但是激活码错误!"); } } else { Response.Write("用户不存在,还没有注册成功!"); } } 第五步:这样完成之后,就可以去自己刚才填写的126邮箱中查看邮件,打开邮箱单击激活,就激活成功了,
然后再去数据库中查看Active的状态,此时应该是True,这样,一个完整的注册并发送邮件加激活的功能就完成了。
