Detecting unhandled errors in ASP.Net applications

For my own reference, here’s how to detect unhandled exceptions in Global.asax:

protected void Application_Error(object sender, EventArgs e)
{
  // Log error
  Exception ex = Server.GetLastError().GetBaseException();
  string msg = String.Format("Ohanterat fel!\r\nAdress: {0}\r\nFelmeddelande: {1}", Request.Url, ex.Message);
  LogHelper.Error(msg, ex);

  Server.ClearError();

  // Display simple error page
  Response.Write("Ett oväntat fel har inträffat...\r\n");
  Response.Write("<br/>\r\n<pre>\r\n");
  Response.Write(ex.ToString());
  Response.Write("<br/>\r\n</pre>\r\n");
  Response.End();
}

We mostly do it like this, if you have a better suggestion, please post a comment 🙂
