注：个人邮箱发送时需要将邮箱密码设置为邮件授权码
邮件发送帮助类一：
public class EmailHelper
{
/// <summary>
/// 发送邮件
/// </summary>
/// <param name="To">收件地址</param>
/// <param name="Name">收件人</param>
/// <param name="Subject">标题</param>
/// <param name="Content">内容</param>
/// <returns></returns>
public static bool SendEmail(string To, string Name, string Subject, string Content)
{
SmtpClient client = new SmtpClient(); //获取或设置用于验证发件人身份的凭据。
client.Credentials = new System.Net.NetworkCredential("邮箱地址", "密码");
client.Port =; //端口号
//获取或设置用于 SMTP 事务的主机的名称或 IP 地址（这里是qq的,163邮箱的是smtp.163.com）
client.Host = "smtp.qq.com";
try
{
client.Send(InitMailMessage(To, Name, Subject, Content));
return true;
}
catch (System.Net.Mail.SmtpException ex)
{
return false;
}
} /// <summary>
/// 初始化信件相关信息
/// </summary>
/// <param name="To">收件地址</param>
/// <param name="name">收件人</param>
/// <param name="Subject">标题</param>

private static MailMessage InitMailMessage(string To, string name, string Subject, string sendEmailContent)
{
MailMessage mail = new MailMessage();
//发件人
mail.From = new MailAddress("邮箱地址", "设置个名称"); //收件人
if (name != "")
{
MailAddress mailAdd = new MailAddress(To, name);
mail.To.Add(mailAdd);
}
else
{
mail.To.Add(To);
}
//主题
mail.Subject = Subject; //内容
mail.Body = sendEmailContent; //邮件主题和正文的编码格式
mail.SubjectEncoding = System.Text.Encoding.UTF8;
mail.BodyEncoding = System.Text.Encoding.UTF8; //邮件正文允许html编码
mail.IsBodyHtml = true;
//优先级
mail.Priority = MailPriority.Normal; //密送——就是将信密秘抄送给收件人以外的人，所有收件人看不到密件抄送的地址
//mail.Bcc.Add(""); //抄送——就是将信抄送给收件人以外的人,所有的收件人可以在抄送地址处看到此信还抄送给谁
mail.CC.Add("抄送人地址"); mail.Attachments.Add(new Attachment(@"G:\2018\vue-devtools.zip")); //添加附件 return mail; }
}
邮件发送帮助类二（感觉这个发的快一点）：
public class EmailHelper
{
private MailMessage mMailMessage; //主要处理发送邮件的内容（如：收发人地址、标题、主体、图片等等）
private SmtpClient mSmtpClient; //主要处理用smtp方式发送此邮件的配置信息（如：邮件服务器、发送端口号、验证方式等等）
private int mSenderPort = ; //发送邮件所用的端口号（htmp协议默认为25）
private string mSenderServerHost = "smtp.exmail.qq.com"; //发件箱的邮件服务器地址（IP形式或字符串形式均可）
private string mSenderPassword = "密码"; //发件箱的密码
private string mSenderUsername = "发件箱的用户名"; //发件箱的用户名
private bool mEnableSsl = false; //是否对邮件内容进行socket层加密传输
private bool mEnablePwdAuthentication = true; //是否对发件人邮箱进行密码验证
private string fromMail = "发件箱的地址"; //发件箱的地址(与用户名一致) /// <summary>
/// 发送邮件
/// </summary>
/// <param name="Receive">接收人邮箱</param>
/// <param name="subject">标题</param>
/// <param name="emailBody">邮件内容</param>
/// <param name="cc">抄送人邮箱</param>
public EmailHelper(List<string> Receive, string subject, string emailBody,List<string>cc)
{ mMailMessage = new MailMessage();
foreach (string item in Receive)
{
mMailMessage.To.Add(item);
}
mMailMessage.From = new MailAddress(fromMail);
mMailMessage.Subject = subject;
mMailMessage.Body = emailBody;
mMailMessage.IsBodyHtml = true;
mMailMessage.BodyEncoding = System.Text.Encoding.UTF8;
mMailMessage.Priority = MailPriority.Normal;
foreach (string item in cc)
{
mMailMessage.To.Add(item);
} } ///<summary>
/// 添加附件
///</summary>
///<param name="attachmentsPath">附件的路径集合，以分号分隔</param>
public void AddAttachments(string attachmentsPath)
{ string[] path = attachmentsPath.Split(';'); //以什么符号分隔可以自定义

for (int i = ; i < path.Length; i++)
{

disposition = data.ContentDisposition;
disposition.CreationDate = File.GetCreationTime(path[i]);
