Question

好吧，我已经完成了我的作业，甚至在这个网站上看了几个例子，但没有用。我的程序旨在发送填写在表单上的数据，并将其发送到电子邮件。除了SmptMailMessage之外，我的其余代码都没有显示任何错误。这是我的代码：

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Net.Mail;

namespace FPSArrestReport
 {
public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
    }

    private void btn1_Click(object sender, EventArgs e)
    {

        SmtpClient SmptMailMessage = new SmtpClient();
        SmptMailMessage mail = new SmtpMailMessage("smtp.gmail.com", 25); // error on this line
         \\on the SmptMailmessage

           //set the to address to the primary email 
      mail.To.Add("xxx@abc.com"); 

     //set the message type and subject and body 
      mail.IsHtmlMessage = true; 
      mail.Subject = ""; 
      mail.Body = "Hello world!"; 

    //send the email 
      mail.Send();   
      }

Answer 1

System.Net.Mail库中没有类型为SmtpMailMessage（或SmptMailMessage）。看起来您正在尝试创建一个SmtpClient实例来发送消息。也许你的意思是做类似的事情;

SmtpClient client = new SmtpClient("smtp.gmail.com", 25); 

MailMessage mail = new MailMessage();
mail.To.Add("xxx@abc.com");
client.Send(mail);

您在这里使用了2个对象 - 一个SmtpMailClient（用于发送）和一个描述该消息的 MailMessage 。

Answer 2

.NET中没有StmpMailMessage类。你想要MailMessage。您还希望将服务器凭据传递给SmtpClient。

这应该是一个简单的解决方案。此外，尝试正确观察您的拼写。：d

    $
    using System;
    using System.Collections.Generic;
    using System.ComponentModel;
    using System.Data;
    using System.Drawing;
    using System.Linq;
    using System.Text;
    using System.Windows.Forms;
    using System.Net.Mail;
    using System.Net;
    namespace WindowsFormsApplication1
    {
        public partial class Form1 : Form
        {
            MailAddress fromAddress = new MailAddress("YourEmailAcct@gmail.com", "NameForIt");
            MailAddress toAddress = new MailAddress("DesinationEmailAddress", "NameForDestination");
            const string fromPassword = "password";
            const string subject = "Subject";
            const string body = "First line of text \n Second line of text.";

            public Form1()
            {
                InitializeComponent();

            }

            private void button1_Click(object sender, EventArgs e)
            {

                SmtpClient client = new SmtpClient()
                {
                    Host = "smtp.gmail.com",
                    Port = 587,
                    EnableSsl = true,
                    DeliveryMethod = SmtpDeliveryMethod.Network,
                    UseDefaultCredentials = false,
                    Credentials = new NetworkCredential(fromAddress.Address, fromPassword)
                };

                try
                {
                    MailMessage message = new MailMessage(fromAddress, toAddress)
                    {
                        Subject = subject,
                        Body = body
                    };

                    client.Send(message);
                }
                catch (Exception ex)
                {
                    MessageBox.Show("There was an error!" + ex.Message);
                }


            }

            }
        }
