Track and Display Error Message in Asp.Net MVC Application Using C#.Net

Error handling one of the most important part of an application development. In  this article I will show you how you can use try , catch and finally block in your mvc application.

Some of previous articles are as follows: Increase Session TimeOut in MVC 4, Simple Login From in Asp.Net MVC Using C#.Net, Bind and Retrieve ListBox Selected Value in MVC Using C#.Net, Bind DropDownList Using Entity Framework in ASP.Net MVC Using C#, Error : SQL Server Compact is not intended for ASP.NET development. .

So for this article first we will create a new mvcapplication and add a model in our application.

using System; using System.Collections.Generic; using System.Linq; using System.Web; namespace ErrorHandeling_In_MVC.Models {     public class ErrorModel     {         public string ErrorMessage { get; set; }         public string FinallyBlockMesage { get; set; }     } }

Now we will create our controller and add the below code in our controller.

using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.Mvc; using ErrorHandeling_In_MVC.Models; namespace ErrorHandeling_In_MVC.Controllers {     public class HomeController : Controller     {         //         // GET: /Home/         /// <summary>         /// Track and Display error message in mvc application using c#.Net         /// </summary>         /// <returns></returns>         public ActionResult Index()         {             ErrorModel objerrormodel = new ErrorModel();             try             {                 int value1 = 0;                 int value2 = 2;                 int finalvalue = value2 / value1;             }             catch (Exception ex)             {                 objerrormodel.ErrorMessage = ex.Message.ToString();             }             finally             {                 objerrormodel.FinallyBlockMesage = "This message assign in finally block.";             }             return View(objerrormodel);         }     } }

In above code we have raised exception by dividing by zero to a number.  We will catch exception in catch block and finally we will raise the final block effect.

Now we will create view in for our controller. Now we will check the view code.

@model ErrorHandeling_In_MVC.Models.ErrorModel @{     ViewBag.Title = "Index"; } <h2>Error Handeling</h2> <ul> <li>Error Message :@Model.ErrorMessage</li> <li>Finally Block :@Model.FinallyBlockMesage</li> </ul>

Now run the application. You will get the exception as shown below.

And final output
