C#中出错:找不到类型或命名空间"SmptMailMessage"

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();   
      }

有一个在System.Net.Mail库中没有这样的类型为SmtpMailMessage(或SmptMailMessage为此事).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.
