这个例子很简单，初学者可以看一下，写的很明白，注释都加了大家看一下就行了，呵呵

实现的方法如下：

_Default : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {

    }
    protected void Button1_Click(object sender, EventArgs e)
    {
        try
        {
            MailMessage objMail = new MailMessage();

            //发件人地址
            objMail.From = new MailAddress(txtForm.Text.ToString().Trim());
            //邮件标题
            objMail.Subject = txttitle.Text.ToString().Trim();
            //邮件标题编码
            objMail.SubjectEncoding = System.Text.Encoding.UTF8;
            //邮件内容
            objMail.Body = txtBody.Text.ToString().Trim();
            //邮件内容编码
            objMail.BodyEncoding = System.Text.Encoding.UTF8;
            //收件人地址在这里可以加多个
            objMail.To.Add(txtTO.Text.ToString().Trim());
            //用SMTP发送邮件的方式
            SmtpClient client = new SmtpClient();
            //用户名和密码
            client.Credentials = new System.Net.NetworkCredential(txtForm.Text.ToString().Trim(), txtPwd.Text.ToString().Trim());
            //服务器名
            client.Host = "SMTP.163.com";
            //发送
            client.Send(objMail);
            ClientScriptManager csm = this.ClientScript;
            csm.RegisterStartupScript(this.GetType(), "sufei", "发送成功");
        }
        catch (Exception ex)
        {
            ClientScriptManager csm = this.ClientScript;
            csm.RegisterStartupScript(this.GetType(), "sufei", ex.Message.ToString().Trim());
        }

    }
}

也可以写在方法里面，这样用起来方便一点点

/// 发送邮件
 /// </summary>
 /// <param name="MailFromAddress">发件人地址</param>
 /// <param name="MailFromUserName">用户名</param>
 /// <param name="MailFormPwd">密码</param>
 /// <param name="MailTitle">邮件标题</param>
 /// <param name="MailBody">邮件内容</param>
 /// <param name="MailTo">收件人地址</param>
 /// <returns>发送成功返回True否则返回False</returns>
 public static Boolean SendMail(string MailFromAddress, string MailFormPwd, string MailTitle, string MailBody, string MailTo)
 {
 try
 {
 MailMessage objMail = new MailMessage();
 //发件人地址
 objMail.From = new MailAddress(MailFromAddress);
 //邮件标题
 objMail.Subject = MailTitle;
 //邮件标题编码
 objMail.SubjectEncoding = System.Text.Encoding.UTF8;
 //邮件内容
 objMail.Body = MailBody;
 //邮件内容编码
 objMail.BodyEncoding = System.Text.Encoding.UTF8;
 //收件人地址在这里可以加多个
 objMail.To.Add(MailTo);
 //用SMTP发送邮件的方式
 SmtpClient client = new SmtpClient();
 //用户名和密码
 client.Credentials = new System.Net.NetworkCredential(MailFromAddress, MailFormPwd);
 string StrMail = "";
 for (int i = 0; i < MailFromAddress.Length; i++)
 {
 if (MailFromAddress.Substring(i, 1).ToString().Trim() == "@")
 {
 StrMail = MailFromAddress.Substring(i + 1, MailFromAddress.Length - i - 1);
 }
 }
 //服务器名
 client.Host = "smtp." + StrMail.ToString().Trim();
 //发送
 client.Send(objMail);
 return true;
 }
 catch (Exception)
 {
 return false;
 }
 }

使用方法

{
 if (MessageSendServices.SendMail(txtFrom.Text.ToString().Trim(), txtFromPwd.Text.ToString().Trim(), txtTitle.Text.ToString().Trim(), txtNeiRong.Text.ToString().Trim(), txtTo.Text.ToString().Trim()))
 {
 ClientScriptManager csm = this.ClientScript;
 csm.RegisterStartupScript(this.GetType(), "one", "" + "邮件发送成功" + "");
 }
 else
 {
 ClientScriptManager csm = this.ClientScript;
 csm.RegisterStartupScript(this.GetType(), "one", "" + "邮件发送失败" + "");
 }
 }
 catch (Exception)
 {
 ClientScriptManager csm = this.ClientScript;
 csm.RegisterStartupScript(this.GetType(), "one", "" + "下发时发生异常信息" + "");
 }
