求vc#中的邮件类

找过了，可是好象关于vc#的少，而且找到的也不怎么满意。
不知道.net framework中有没有自带的呢？

我是在vc#中使用的，提示没有System.Web.Mail命名空间。

先要添加引用
using System.Web.Mail;

出现下面的错误：error CS0234: 类型或命名空间名称“Mail”在类或命名空间“System.Web”中不存在(是否缺少程序集引用？)

添加引用就可以了.System.Web.DLL

收邮件的话我最近只写了收pop3协议的 hotmail就不能收

有的，我刚做了一个小小的邮件发送的
//发送邮件
System.Web.Mail.MailMessage myEmail = new System.Web.Mail.MailMessage(); // SET MESSAGE PARAMETERS
myEmail.From = "[email protected]";
myEmail.To = "[email protected]";
myEmail.Subject = "主题"; //主题
myEmail.BodyFormat = System.Web.Mail.MailFormat.Html;
myEmail.Body = "内容" ; //正文
//SEND THE MESSAGE
System.Web.Mail.SmtpMail.Send(myEmail);

刚才我做了一个，明明提示成功了，为什么我查看邮件的时候还没有呢？
代码如下：
private void button1_Click(object sender, System.EventArgs e)
{
MailMessage mm = new MailMessage(); mm.From="[email protected]";
mm.To="[email protected]";
mm.Subject="主题";
mm.Body="我爱你!";
mm.BodyFormat=MailFormat.Html;
mm.Priority=MailPriority.High;
try
{
SmtpMail.Send(mm);
MessageBox.Show("成功了！");
}
catch
{
MessageBox.Show("错误了！");
}
}

调试易
