Web 配置设置 -
<appSettings>
<add key="MailServer" value="127.0.0.1"/>
<add key="MailReciever" value="you@yourSite.com"/>
<add key="LogName" value="EmpostErrLog"/>
</appSettings>
<system.net>
<mailSettings>
<smtp from="admin@yourSite.com">
<network host="127.0.0.1"/>
</smtp>
</mailSettings>
</system.net>
调用方法 -
catch(Exception ex)
{
string strMsg = "日期 : " + DateTime.Now.ToString("dd/MMM/yyyy HH:mm:ss") + " 错误 : " + ex.Message + " 控件 : " + ((Control)sender).ClientID.ToString() + " 页面 : " + Page;
errorHandler objErrorHandler = new errorHandler();
objErrorHandler.MsgType = MessageType.MailAndEventLog;
objErrorHandler.RaiseError(strMsg,ex);
}
希望能有所帮助。
