问题描述

大家好，



我在下面的代码中得到以下错误，请您查看下面的代码，让我知道为什么它发生在我的代码中代码背后。



错误：方法'发送'没有重载需要'5'参数

  protected   void  ImgBtnSubmit_Click（ object  sender，ImageClickEventArgs e）

 尝试 
 {
 
  string  toadd =   [e-mail]; 
  var  fromAddress =   info @ abc。 co.uk; 
 
  var  toAddress = toadd;

提前感谢。

解决方案

错误非常明确：方法没有重载'发送'需要'5'参数

这是真的： http://msdn.microsoft.com/en-us/library/system.net.mail.smtpclient.send(v = vs.110）.aspx [ ^ 有一个参数，一个参数一个。没有采用密件抄送字符串的方法。

请尝试使用MailMessage对象，smtp.Send不会采用5参数。

  protected   void  ImgBtnSubmit_Click（ object  sender，ImageClickEventArgs e）
 {
  try  
 {
 
  string  toadd =   [e-mail]; 
  var  fromAddress =   info @ abc。 co.uk; 
 
  var  toAddress = toadd; 
  const   string  fromPassword =   abc; 
  string  subject =  联络; 
 
  string  bcc =   [e-mail]; 
  string  body =  < table border = 1>< tr>< td>名称< / td>< td> + txtname.Text +  < / td>< / tr> + 
  < tr>< td>电话< / td>< td> + txttel.Text +  < / td>< / tr> + 
  < ; tr>< td>移动< / td>< td> + txtmobile.Text +  < / td>< / tr> + 
  < tr> ;< td>电子邮件< / td>< td> + txtemail.Text +  < / td>< / tr> + 
   < tr>< td>查询< / td>< td>  + txtquery.Text +  < / td>< / tr>< / table> ; 
 
  var  smtp =  new  System.Net。 Mail.SmtpClient（）; 
 {
 smtp.Host =   mail.abc.co。英国; 
 smtp.Port =  25 ; 
 smtp.EnableSsl =  false ; 
 smtp.DeliveryMethod = System.Net.Mail.SmtpDeliveryMethod.Network; 
 smtp.Credentials =  new  NetworkCredential（fromAddress，from fromPassword）; 
 smtp.Timeout =  20000 ; 
} 
 MailMessage msg =  new  MailMessage（）; 
 msg.From =  new  MailAddress（fromAddress）; 
 msg.To.Add（ new  MailAddress（toAddress））; 
 msg.Bcc.Add（ new  MailAddress（bcc））; 
 msg.Subject = subject; 
 msg.Body = body; 
 msg.IsBodyHtml =  true ; 
 
 smtp.Send（msg）; 
 
 Response.Redirect（  replycontact.aspx）; 
 
 txtname.Text =  ; 
 txttel.Text =  ; 
 txtmobile.Text =  ; 
 txtemail.Text =  ; 
 txtquery.Text =  ; 
} 
  catch （例外）{} 
} 

< blockquote>答案很简单：



SmtpClient只有两种Send方法。第一个只需要一个MailMessage实例，第二个只需要四个字符串参数。



看这里： SmtpClient.Send方法 [ ^ ]。

Hi all,

I got a given below error in my code below, please have you look at my code below and let me know why its happened in my code behind.

error: No overload for method 'Send' takes '5' arguments

protected void ImgBtnSubmit_Click(object sender, ImageClickEventArgs e)
  {
      try
      {

          string toadd = "[e-mail]";
          var fromAddress = "[e-mail]";

          var toAddress = toadd;

          }
          smtp.Send(fromAddress,toAddress,bcc, subject,body);  // here am getting above mentioned error

          Response.Redirect("replycontact.aspx");

          txtname.Text = "";

      }
      catch (Exception) { }
  }

thanks in advance.

解决方案

The error is pretty explicit: "No overload for method 'Send' takes '5' arguments"
And it's true: http://msdn.microsoft.com/en-us/library/system.net.mail.smtpclient.send(v=vs.110).aspx[^] there is one with one parameter, and one with four. There is no method which takes a bcc string.

please try with MailMessage object and smtp.Send will not take 5 argument.

protected void ImgBtnSubmit_Click(object sender, ImageClickEventArgs e)
    {
        try
        {

            string toadd = "[e-mail]";
            var fromAddress = "[e-mail]";

            var toAddress = toadd;
            const string fromPassword = "abc";
            string subject = "Contact";

            string bcc = "[e-mail]";
            string body = "<table border=1><tr><td> Name </td><td>" + txtname.Text + "</td></tr>" +
                    "<tr><td> Telephone </td><td> " + txttel.Text + "</td></tr>" +
                    "<tr><td> Mobile </td><td> " + txtmobile.Text + "</td></tr>" +
                    "<tr><td> Email </td><td> " + txtemail.Text + "</td></tr>" +
                    "<tr><td> Query </td><td> " + txtquery.Text + "</td></tr></table>";

            var smtp = new System.Net.Mail.SmtpClient();
            {
                smtp.Host = "mail.abc.co.uk";
                smtp.Port = 25;
                smtp.EnableSsl = false;
                smtp.DeliveryMethod = System.Net.Mail.SmtpDeliveryMethod.Network;
                smtp.Credentials = new NetworkCredential(fromAddress, fromPassword);
                smtp.Timeout = 20000;
            }
            MailMessage msg = new MailMessage();
            msg.From = new MailAddress(fromAddress);
            msg.To.Add(new MailAddress(toAddress));
            msg.Bcc.Add(new MailAddress(bcc));
            msg.Subject = subject;
            msg.Body = body;
            msg.IsBodyHtml = true;

            smtp.Send(msg); 

            Response.Redirect("replycontact.aspx");

            txtname.Text = "";
            txttel.Text = "";
            txtmobile.Text = "";
            txtemail.Text = "";
            txtquery.Text = "";
        }
        catch (Exception) { }
    }

The answer is simple:

SmtpClient has exactly two Send methods. The first takes simply a MailMessage instance and the second takes exactly four string parameters.

Look here: SmtpClient.Send Method[^].

Being able to read is a good thing, use it every day!

Cheers!
