ASP.NET实现邮箱发送验证码

*ASP.NET实现邮箱发送验证码

一：先在前台添加一个button按钮，用来点击发送验证码

二：封装一个类实现邮箱发送验证码
public class Email
{
///
/// 发送者
///
public string mailFrom { get; set; }

    /// <summary>
    /// 收件人
    /// </summary>
    public string[] mailToArray { get; set; }

    /// <summary>
    /// 抄送
    /// </summary>
    public string[] mailCcArray { get; set; }

    /// <summary>
    /// 标题
    /// </summary>
    public string mailSubject { get; set; }

    /// <summary>
    /// 正文
    /// </summary>
    public string mailBody { get; set; }

    /// <summary>
    /// 发件人密码
    /// </summary>
    public string mailPwd { get; set; }

    /// <summary>
    /// SMTP邮件服务器
    /// </summary>
    public string host { get; set; }

    /// <summary>
    /// 正文是否是html格式
    /// </summary>
    public bool isbodyHtml { get; set; }

    /// <summary>
    /// 附件
    /// </summary>
    public string[] attachmentsPath { get; set; }

    public bool Send()
    {
        //使用指定的邮件地址初始化MailAddress实例
        MailAddress maddr = new MailAddress(mailFrom);
        //初始化MailMessage实例
        MailMessage myMail = new MailMessage();


        //向收件人地址集合添加邮件地址
        if (mailToArray != null)
        {
            for (int i = 0; i < mailToArray.Length; i++)
            {
                myMail.To.Add(mailToArray[i].ToString());
            }
        }

        //向抄送收件人地址集合添加邮件地址
        if (mailCcArray != null)
        {
            for (int i = 0; i < mailCcArray.Length; i++)
            {
                myMail.CC.Add(mailCcArray[i].ToString());
            }
        }
        //发件人地址
        myMail.From = maddr;

        //电子邮件的标题
        myMail.Subject = mailSubject;

        //电子邮件的主题内容使用的编码
        myMail.SubjectEncoding = Encoding.UTF8;

        //电子邮件正文
        myMail.Body = mailBody;

        //电子邮件正文的编码
        myMail.BodyEncoding = Encoding.Default;

        myMail.Priority = MailPriority.High;

        myMail.IsBodyHtml = isbodyHtml;

        //在有附件的情况下添加附件
        try
        {
            if (attachmentsPath != null && attachmentsPath.Length > 0)
            {
                Attachment attachFile = null;
                foreach (string path in attachmentsPath)
                {
                    attachFile = new Attachment(path);
                    myMail.Attachments.Add(attachFile);
                }
            }
        }
        catch (Exception err)
        {
            throw new Exception("在添加附件时有错误:" + err);
        }

        SmtpClient smtp = new SmtpClient();
        //指定发件人的邮件地址和密码以验证发件人身份
        smtp.Credentials = new System.Net.NetworkCredential(mailFrom, mailPwd);


        //设置SMTP邮件服务器
        smtp.Host = host;

        try
        {
            //将邮件发送到SMTP邮件服务器
            smtp.Send(myMail);
            return true;

        }
        catch (System.Net.Mail.SmtpException ex)
        {
            return false;
        }

    }

}

三：还需要额外加载的类
Using System.Net.Mail;
Using System.Net;

四：生成一个6位长度的验证码
public string CreateValidateCode(int length)
{
int[] randMembers = new int[length];
int[] validateNums = new int[length];
string validateNumberStr = “”;
//生成起始序列值
int seekSeek = unchecked((int)DateTime.Now.Ticks);
Random seekRand = new Random(seekSeek);
int beginSeek = (int)seekRand.Next(0, Int32.MaxValue - length * 10000);
int[] seeks = new int[length];
for (int i = 0; i < length; i++)
{
beginSeek += 10000;
seeks[i] = beginSeek;
}
// 生成随机数字
for (int i = 0; i < length; i++)
{
Random rand = new Random(seeks[i]);
int pownum = 1 * (int)Math.Pow(10, length);
randMembers[i] = rand.Next(pownum, Int32.MaxValue);

        }
        //生成随机数字
        for (int i = 0; i < length; i++)
        {
            string numStr = randMembers[i].ToString();
            int numLength = numStr.Length;
            Random rand = new Random();
            int numPosition = rand.Next(0, numLength - 1);
            validateNums[i] = Int32.Parse(numStr.Substring(numPosition, 1));
        }
        // 生成验证码
        for (int i = 0; i < length; i++)
        {
            validateNumberStr += validateNums[i].ToString();
        }
        return validateNumberStr;
    }

五：使用qq邮箱的话需要开启一个服务
六：邮箱验证码的获取
//验证码 邮箱获取
public string CodeEmail(string emailinfo)
{
//Response.Write(“”);
//return View(“Register”);
return YZCode(emailinfo);
}
public string YZCode(string LoginEmial)
{
string code = CreateValidateCode(6);
YZMCode = code;
Email email = new Email
{
host = “smtp.qq.com”,
mailBody = code,
mailFrom = “**********@qq.com”,
mailPwd = “zlihferffrhdfjif”,
mailSubject = “来自明日yi游的登录验证码！”,
mailToArray = new string[] { LoginEmial }
};
bool b = email.Send();
if (b == true)
{
return “验证码已发送 请查收！”;
}
else
{
return “您输入的账号有误请重新输入”;
}
}
完成以上步骤就可实现邮箱发送验证码的功能了。
