Log exception to file in c# .net core application explained

In production environment when any bug gets reported at that time as developer wants to get the exception details of bug to resolve the issue on high priority.
In some case there might be situation where exception is not logged in table but developer wants to check the bug immediately. for that purpose we need to write the
exception details including stack trace of bug in file. To implement this easily i am going to demonstrate the implementation of custom logging in file as below.

First we need to construct the exception and logger method in custom logger class as shown below.


public class CustomLogger { public static List<string> ConstructExceptionDetails(Exception ex,string FunctionName) { return new List<string>() { $"{DateTime.Now} - {FunctionName}", $"Exception: {ex.Message}", $"StackTrace: {ex.StackTrace}", $"InnerException: {ex.InnerException?.…

Internet explorer Loads pages from cache issue resolution in asp.net

Internet explorer have tendency to load pages from cache for same requested URL. Which makes thing worse where the content of the web page updated frequently. In this situation Internet Explorer not send request to the server for page rendering. To resolve the issue in asp.net there are two option available. Write the HTML code in head tag or write server side code to tell Internet explorer to not to load pages from cache.

If you are trying to add code in design or HTML page then add following code

<HTML><HEAD>
<META HTTP-EQUIV="Pragma" CONTENT="no-cache">
<META HTTP-EQUIV="Expires" CONTENT="-1">
</HEAD><BODY>
</BODY>
</HTML>  

In Asp.NET, you can do it on a page-by-page granularity by using this set of methods prior to calling the web page by following way.


HttpContext.Response.Cache.SetExpires(DateTime.UtcNow.AddDays(-1));
HttpContext.Response.Cache.SetValidUntilExpires(false);
HttpContext.Response.Cache.SetRevalidation(System.Web.HttpCacheRevalidation.AllCaches);
HttpContext.Response.Cache.SetCacheability(System.Web.HttpCacheability.NoCache);
HttpContext.Response.Cache.SetNoStore();

The above code also works well in Asp.Net MVC 3.0

Happy Coding !!! :)
