Error Reporting / Notification Service

Introduction

This tip/code will be helpful to a developer after an application has been launched or configured on a client's server. After a website is live or launched, users will access the website. If a user faces an unexpected error, then no one gets to know what error it was. Developer or website admin will never get to know about such errors on live websites. So I coded for that to enable the website admin or developer to know about errors.

Using the Code

In this sample web application, three classes are available:

• ErrorReporting
• Email
• Config

ErrorReporting.cs

We have a function SendApplicationError which accepts five parameters which are optional:

• vstrErrorMessage (to set custom error message)
• vstrErrorCode (to set custom error code)
• vstrErrorType (to set custom error type)
• vstrStackTrace (to set custom error stack trace)
• vstrRedirectURL (out parameter to set auto redirection if any specific error found)

Config oConfig = new Config();
string strApplicationName = oConfig.getApplicationName();
string ToAddress = oConfig.GetString(String.Format("SMTP.Error.EamilTo"));
string FromAddress = oConfig.GetString(String.Format("SMTP.Error.EamilFrom"));
string strBCC = oConfig.GetString(String.Format("SMTP.DefaultBCCEmail"));

if (oConfig.isErrorEnable() == false)
{
    vstrRedirectURL = "";
    return;
}

Above values will be fetched from web.config using the customized config class.

Email.cs

Using this class, the system will automatically send an email to the respective website admin or mentioned email address and also set default BCC email if provided in web.config.

Config.cs

This customized class is used to fetch information or key values from web.config. Using this class, we also can set datatype, i.e., string, int, etc..
