一个比较好的.net 3.5的异常报告类

实现的是当有异常时,发邮件报告 
using System; 
using System.Collections.Generic; 
using System.Linq; 
using System.Web; 
using System.Net.Mail; 
namespace Experiement 
{ 
    public static class MyExtension 
    { 
        public static void SendErrorEmail(this Exception ex) 
        { 
            MailMessage mailMessage = new MailMessage(new MailAddress("from@gmail.com") 
                                       , new MailAddress("to@gmail.com")); 
            mailMessage.Subject = "Exception Occured in your site"; 
            mailMessage.IsBodyHtml = true; 
            System.Text.StringBuilder errorMessage = new System.Text.StringBuilder(); 
            errorMessage.AppendLine(string.Format("<B>{0}</B>:{1}","Exception",ex.Message)); 
            errorMessage.AppendLine(string.Format("<B>{0}</B>:{1}", "Stack Trace", ex.StackTrace)); 
            if (ex.InnerException != null) 
            { 
                errorMessage.AppendLine(string.Format("<B>{0}</B>:{1}", " Inner Exception", ex.InnerException.Message)); 
                errorMessage.AppendLine(string.Format("<B>{0}</B>:{1}", "Inner Stack Trace", ex.InnerException.StackTrace)); 
            } 
            mailMessage.Body = errorMessage.ToString(); 
            System.Net.NetworkCredential networkCredentials = new 
            System.Net.NetworkCredential("youraccount@gmail.com", "password"); 
            
            SmtpClient smtpClient = new SmtpClient(); 
            smtpClient.EnableSsl = true; 
            smtpClient.UseDefaultCredentials = false; 
            smtpClient.Credentials = networkCredentials; 
            smtpClient.Host = "smtp.gmail.com"; 
            smtpClient.Port = 587; 
            smtpClient.Send(mailMessage); 
            
        } 
    } 
} 

使用: 
using System; 
namespace Experiement 
{ 
    public partial class WebForm1 : System.Web.UI.Page 
    { 
        protected void Page_Load(object sender,System.EventArgs e) 
        { 
            try 
            { 
                throw new Exception("My custom Exception"); 
            } 
            catch (Exception ex) 
            { 
                ex.SendErrorEmail(); 
                Response.Write(ex.Message); 
            } 
        } 
    } 
}
