copied!<p>Seems like you're looking for some kind of base-level application error handling. Why not add the definition for the Application_Error method in your Global.asax file. This will catch any un-handled exceptions that crop up in your application (from controllers, or other libraries or views etc.)</p> <p>Here's the example: add this to your Global.asax:</p> <pre><code>protected void Application_Error(object sender, EventArgs e) { Exception exception = Server.GetLastError(); Response.Clear(); //Do your logging here. //Redirect to an appropriate error page. } </code></pre> <p>If you're wondering about what to log, there's plenty of information within the exception object that you've got access to inside this method. I usually write a class which writes out some of this information to a text file. Here's an example (in a class called Log) - it's not the most comprehensive method and I'm sure more information can be extracted from the exception object but:</p> <pre><code>public class Log { private StreamWriter _writer; public void WriteErrorMessage(string errorMessage, string pageUrl, Exception e) { _writer = new StreamWriter("LOG_FILE_OUTPUT_PATH_HERE.txt", true); StringBuilder fullError = new StringBuilder(); fullError.AppendLine("Error log: " + DateTime.Now); fullError.AppendLine(errorMessage); fullError.AppendLine("Error raised on: " + pageUrl); fullError.AppendLine("Associated exception message: " + e.Message + "\n" + e.InnerException); fullError.AppendLine("Exception class: " + e.GetType().ToString()); fullError.AppendLine("Exception source: " + e.Source.ToString()); fullError.AppendLine("Exception method: " + e.TargetSite.Name.ToString()); fullError.AppendLine(); _writer.WriteLine(fullError); _writer.Flush(); _writer.Close(); } } </code></pre> <p>Then, in your Application_Error method (that we defined above) just call:</p> <pre><code>new Log().WriteErrorMessage("Global error has occurred.", Request.Url.ToString(), exception); </code></pre>
