C#如何实现textbox内容自动发送到指定邮箱？

Answer 1

using System.Net.Mail

/// <summary>
/// 发送邮件程序
/// </summary>
/// <param name="from">发送人邮件地址</param>
/// <param name="fromname">发送人显示名称</param>
/// <param name="to">发送给谁（邮件地址）</param>
/// <param name="subject">标题</param>
/// <param name="body">内容</param>
/// <param name="username">邮件登录名</param>
/// <param name="password">邮件密码</param>
/// <param name="server">邮件服务器</param>
/// <param name="files">附件</param>
/// <returns>send ok</returns>
/// 调用方法 SendMail("abc@126.com", "某某人", "cba@126.com", "你好", "我测试下邮件", "邮箱登录名", "邮箱密码", "smtp.126.com", "");
private string SendMail(string from, string fromname, string to, string subject, string body, string username, string password, string server, string[] files)
{
try
{
//邮件发送类
MailMessage mail = new MailMessage();
//是谁发送的邮件
mail.From = new MailAddress(from, fromname);
//发送给谁
mail.To.Add(to);
//标题
mail.Subject = subject;
//内容编码
mail.BodyEncoding = Encoding.Default;
//发送优先级
mail.Priority = MailPriority.High;
//邮件内容
mail.Body = body;
//是否HTML形式发送
mail.IsBodyHtml = true;
//附件
for (int i = 0; i < fujian.Length; i++)
{
mail.Attachments.Add(new Attachment(fujian[i]));
}
//邮件服务器和端口
SmtpClient smtp = new SmtpClient(server, 25);
smtp.UseDefaultCredentials = true;
//指定发送方式
smtp.DeliveryMethod = SmtpDeliveryMethod.Network;
//指定登录名和密码
smtp.Credentials = new System.Net.NetworkCredential(username, password);
//超时时间
smtp.Timeout = 10000;
smtp.Send(mail);
return "send ok";
}
catch (Exception exp)
{
return exp.Message;
}
}

调用上面函数即可

Answer 2

#region
//email是邮箱名，txtbox1是文件框里的内容
public static void Sends(string email,string txtbox1)
{
string formto = "发件箱地址";
string to = email; //接收邮箱
string content = "";
string body = txtbox1;
string name = "发件箱";
string upass = "密码";
string smtp = "smtp地址";
SmtpClient _smtpClient = new SmtpClient();
_smtpClient.DeliveryMethod = SmtpDeliveryMethod.Network;//指定电子邮件发送方式
_smtpClient.Host = smtp; //指定SMTP服务器
_smtpClient.Credentials = new System.Net.NetworkCredential(name, upass);//用户名和密码
MailMessage _mailMessage = new MailMessage();
//发件人，发件人名
_mailMessage.From = new MailAddress(formto, "别名");
//收件人
_mailMessage.To.Add(to);
_mailMessage.SubjectEncoding = System.Text.Encoding.GetEncoding("gb2312");
_mailMessage.Subject = content;//主题

_mailMessage.Body = body;//内容
_mailMessage.BodyEncoding = System.Text.Encoding.GetEncoding("gb2312");//正文编码
_mailMessage.IsBodyHtml = true;//设置为HTML格式
_mailMessage.Priority = MailPriority.High;//优先级
try
{
_smtpClient.Send(_mailMessage);
}
catch (Exception)
{

}

}
#endregion
