c# - 如何发送邮件，邮件正文作为参数并使用线程 - C#

Question

我有一个问题，我正在尝试使用像这样的一种结构发送邮件:

private void SendMail()
{

    var client = new SmtpClient("smtp.gmail.com", 587)
    {
        Credentials = new NetworkCredential("mymail@mail.com", "mypassword"),
        EnableSsl = true
    };
    client.Send("mymail@mail.com", "AdressClient@mail.com", "Subject", "Body");
}

好吧，这个结构工作得很好，但会导致我的主程序延迟，因此我想在另一个线程中执行 SendMail 函数，如下所示:

private void ButtonTestSendMail_Click(object sender, EventArgs e)
    {
        //THREAD
        Thread ThreadSendEmail = new Thread(new ThreadStart(this.SendMail));
        ThreadSendEmail .IsBackground = true;
        ThreadSendEmail .Start();
    }


private void SendMail()
{   
   var client = new SmtpClient("smtp.gmail.com", 587)
   {
      Credentials = new NetworkCredential("mymail@mail.com", "mypassword"),
      EnableSsl = true
   };
   client.Send("mymail@mail.com", "AdressClient@mail.com", "Subject", "Body");
}

此时我注意到我需要更改邮件的参数，例如 AdressClient@mail.com、主题和正文。

但我不知道怎么做:/

我怎样才能写一个接受参数的线程，像这样:

private void ButtonTestSendMail_Click(object sender, EventArgs e)
        {
            string Body = "BodyTest";
            string AdressMail = "AdressMail@test.com";
            string Subject = "SubjectTest";
        //THREAD
        Thread ThreadSendEmail = new Thread(new ThreadStart(this.SendMail(Body,AdressMail,Subject));
        ThreadSendEmail .IsBackground = true;
        ThreadSendEmail .Start();
    }


    private void SendMail(string Body, string Adress, string Subject)
    {   
       var client = new SmtpClient("smtp.gmail.com", 587)
       {
          Credentials = new NetworkCredential("mymail@mail.com", "mypassword"),
          EnableSsl = true
       };
       client.Send("mymail@mail.com", Adress, Subject, Body);
    }

我试过了但没有用，我有一个 MethodName Expected 和一个错误在这一行的通知:

Thread ThreadSendEmail = new Thread(new ThreadStart(this.SendMail(Body,AdressMail,Subject));

如何编写接受参数的线程？谢谢你的帮助!最好的问候!

Answer 1

你快到了:

Thread ThreadSendEmail = new Thread(() => this.SendMail(Body,AdressMail,Subject));

lambda 可以解决问题。您不能直接调用 SendMail，您希望将其作为未调用的函数传递。

请注意，如果您的 ASP.NET 进程回收(可能是因为您正在部署)，线程将被粗鲁地中止。邮件将丢失。
