I would consider simplifying your web application by plugging in <a href="http://code.google.com/p/elmah/" rel="noreferrer">Elmah</a>.

You add the Elmah assembly to your project and then configure your web.config. It will then log exceptions created at controller or page level. It can be configured to log to various different places (like SQL Server, Email etc). It also provides a web frontend, so that you can browse through the log of exceptions.

Its the first thing I add to any asp.net mvc app I create.

I still use log4net, but I tend to use it for logging debug/info, and leave all exceptions to Elmah.

The Error.aspx view is defined like this:

<pre><code>namespace MvcApplication1.Views.Shared
{
 public partial class Error : ViewPage&lt;HandleErrorInfo&gt;
 {
 }
}
</code></pre>

The HandleErrorInfo has three properties:
string ActionName
string ControllerName
Exception Exception

You should be able to access HandleErrorInfo and therefore the Exception within the view.

You can hook into the OnError event in the Global.asax.

Something like this:

<pre><code>/// &lt;summary&gt;
/// Handles the Error event of the Application control.
/// &lt;/summary&gt;
/// &lt;param name="sender"&gt;The source of the event.&lt;/param&gt;
/// &lt;param name="e"&gt;The &lt;see cref="System.EventArgs"/&gt; instance containing the event data.&lt;/param&gt;
protected void Application_Error(object sender, EventArgs e)
{
 if (Server != null)
 {
 Exception ex = Server.GetLastError();

 if (Response.StatusCode != 404 )
 {
 Logging.Error("Caught in Global.asax", ex);
 }

 }


}
</code></pre>

MVC3
 
Create Attribute that inherits from HandleErrorInfoAttribute and includes your choice of logging

<pre><code>public class ErrorLoggerAttribute : HandleErrorAttribute 
{
 public override void OnException(ExceptionContext filterContext)
 {
 LogError(filterContext);
 base.OnException(filterContext);
 }

 public void LogError(ExceptionContext filterContext)
 {
 // You could use any logging approach here

 StringBuilder builder = new StringBuilder();
 builder
 .AppendLine("----------")
 .AppendLine(DateTime.Now.ToString())
 .AppendFormat("Source:\t{0}", filterContext.Exception.Source)
 .AppendLine()
 .AppendFormat("Target:\t{0}", filterContext.Exception.TargetSite)
 .AppendLine()
 .AppendFormat("Type:\t{0}", filterContext.Exception.GetType().Name)
 .AppendLine()
 .AppendFormat("Message:\t{0}", filterContext.Exception.Message)
 .AppendLine()
 .AppendFormat("Stack:\t{0}", filterContext.Exception.StackTrace)
 .AppendLine();

 string filePath = filterContext.HttpContext.Server.MapPath("~/App_Data/Error.log");

 using(StreamWriter writer = File.AppendText(filePath))
 {
 writer.Write(builder.ToString());
 writer.Flush();
 }
 }
</code></pre>

Place attribute in Global.asax RegisterGlobalFilters

<pre><code> public static void RegisterGlobalFilters(GlobalFilterCollection filters)
 {
 // filters.Add(new HandleErrorAttribute());
 filters.Add(new ErrorLoggerAttribute());
 }
</code></pre>

I'm currently using log4net in my ASP.NET MVC application to log exceptions. The way I'm doing this is by having all my controllers inherit from a BaseController class. In the BaseController's OnActionExecuting event, I log any exceptions that may have occurred:

<pre><code>protected override void OnActionExecuted(ActionExecutedContext filterContext)
{
 // Log any exceptions
 ILog log = LogManager.GetLogger(filterContext.Controller.GetType());

 if (filterContext.Exception != null)
 {
 log.Error("Unhandled exception: " + filterContext.Exception.Message +
 ". Stack trace: " + filterContext.Exception.StackTrace, 
 filterContext.Exception);
 }
}
</code></pre>

This works great if an unhandled exception occurred during a controller action.

As for 404 errors, I have a custom error set up in my web.config like so:

<pre><code>&lt;customErrors mode="On"&gt;
 &lt;error statusCode="404" redirect="~/page-not-found"/&gt;
&lt;/customErrors&gt;
</code></pre>

And in the controller action that handles the "page-not-found" url, I log the original url being requested:

<pre><code>[AcceptVerbs(HttpVerbs.Get)]
public ActionResult PageNotFound()
{
 log.Warn("404 page not found - " + Utils.SafeString(Request.QueryString["aspxerrorpath"]));

 return View();
}
</code></pre>

And this also works.

The problem that I'm having is how to log errors that are on the .aspx pages themselves. Let's say I have a compilation error on one of the pages or some inline code that will throw an exception:

<pre><code>&lt;% ThisIsNotAValidFunction(); %&gt;
&lt;% throw new Exception("help!"); %&gt;
</code></pre>

It appears that the HandleError attribute is correctly rerouting this to my Error.aspx page in the Shared folder, but it is definitely not being caught by my BaseController's OnActionExecuted method. I was thinking I could maybe put the logging code on the Error.aspx page itself, but I'm unsure of how to retrieve the error information at that level.
