项目中报错邮件方法

　　项目中使用报错邮件的重要性,O(∩_∩)O~嘿嘿...重要性我就不多说,只说一点:可以帮助你快速定位项目中没有被捕获的BUG...这个报错邮件的方法一般都是添加在一个单独的类(例如BaseClass)中,给取数据的接口,登陆,详情页,...这些要害"部门"使用,这些页面的.cs文件都继承至这个类(BaseClass).

override protected void OnInit(EventArgs e)
    {
        InitializeComponent();
        base.OnInit(e);
    }

    private void InitializeComponent()
    {
        Error += Page_Error;
    }

    void Page_Error(object sender, EventArgs e)
    {
        //可以添加一个缓存
        string CacheKey = "errorinfo";
        try
        {
            Exception ex = Server.GetLastError();
            string errMsg = ex.Message;
            string param = string.Empty;
            string url = HttpContext.Current.Request.Url.Authority + HttpContext.Current.Request.Url.AbsolutePath + errMsg;

            Hashtable ErrorTable = HttpContext.Current.Cache[CacheKey] as Hashtable;
            if (ErrorTable == null)
            {
                ErrorTable = new Hashtable();
                HttpContext.Current.Cache.Insert(CacheKey, ErrorTable, null, DateTime.Now.AddHours(1), System.Web.Caching.Cache.NoSlidingExpiration);
            }
            if (ErrorTable.Contains(url)) 
            { 
                return;
            }
            else
            {
                //没找到
                ErrorTable.Add(url, errMsg);
            }

            if (Request.Form != null)
                param += Environment.NewLine + "接收Form:" + Server.UrlDecode(Request.Form.ToString());

            if (Request.QueryString != null)
                param += Environment.NewLine + "接收QueryString：" + Server.UrlDecode(Request.QueryString.ToString());

            if (Request.UrlReferrer != null)
            {
                errMsg += Environment.NewLine + "来源：" + Request.UrlReferrer.AbsoluteUri;
            }

            //这个收件人邮箱可以在配置文件中配置: <add key="EmailTo" value="renyong@soufun.com,bilingyun@soufun.com"></add>
            //string mailTo = ConfigurationManager.AppSettings["EmailTo"];
            //也可以直接写:
            string mailTo = "123@126.com,456@126.com";
            if (string.IsNullOrEmpty(mailTo))
            {
                mailTo = "123@soufun.com";
            }

            string[] arrMailTo = mailTo.Split(',');
            //这个地方的发件人,一写成你项目的邮箱地址..(也可以随意配一个你知道的邮箱地址...O(∩_∩)O~)
            MailMessage mm = new MailMessage(new MailAddress("issosystem@126.com"), new MailAddress(arrMailTo[0]));
            int arrLength = arrMailTo.Length;
            if (arrLength > 0)
            {
                for (int i = 0; i < arrLength; i++)
                {
                    mm.To.Add(new MailAddress(arrMailTo[i]));
                }
            }

            mm.Subject = HttpContext.Current.Request.ServerVariables["Local_addr"] + "  " + Request.Url.Authority + "   项目报错信息";//
            StringBuilder sbBody = new StringBuilder("发生时间：" + DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss"));
            sbBody.Append(Environment.NewLine + "发生异常页：" + HttpContext.Current.Request.Url.AbsoluteUri);
            if (HttpContext.Current.Request.UrlReferrer != null)
            {

            SmtpClient sendBox = new SmtpClient("mail.126.com");//你公司的邮件服务器
            sendBox.Send(mm);
