请高手帮我一下问什么会有这个问题,如何解决
这是一个类
using System;
using System.Web.Mail;

namespace WebA
{
/// <summary>
/// Mailsend 的摘要说明。
/// </summary>
public class Email
{
private MailMessage newMail;
public Email(string txtTo,string txtMessage)
{
newMail=new MailMessage();
newMail.From="TianHeng@TianHeng.com";
newMail.To=txtTo;
newMail.Subject="天恒购书网站密码取回信！";
newMail.Body=txtMessage;
newMail.BodyFormat=System.Web.Mail.MailFormat.Html;
}
public void SendEmail()
{
SmtpMail.Send(newMail);
}

}
}
----------------------------------------------------------------------
这是发送
private void Button2_Click(object sender, System.EventArgs e)
{
Email my=new Email(TextBox2.Text,TextBox3.Text);
my.SendEmail();
}
-------------------------------------------------
下面是出现的问题
Server Error in '/WebA' Application.
