Creating Extension Method for Enumerated Type

In C#, you can extend the functionality of  Enumerated type by  using extension method same as for other types. Here , I will show you a simple example of creating extension method for Enumerated  type.

In my previous posts, I explained Check Internet Connection using C#, SQL Server Database BackUp using C#, Partial Methods, Contextual Keyword, C# Static Methods and some other articles related to C#, ASP.Net and SQL Server .

Below, I have created an extension method for DayofWeek enumarated type.

/// <summary>

/// Creating Extension Method for Enumarated Type

/// </summary>

/// <param name="day"></param>

/// <returns></returns>

public static string ToDoAlret(this DayOfWeek day)

{

   string strAlert = string.Empty;

   switch (day)

   {

     case DayOfWeek.Sunday:

        strAlert = "Cricket";

        break;

     case DayOfWeek.Monday:

         strAlert = "Reading";

         break;

     case DayOfWeek.Tuesday:

         strAlert = "Meeting";

         break;

     case DayOfWeek.Wednesday:

         strAlert = "Club";

         break;

     case DayOfWeek.Thursday:

         strAlert = "Movie";

         break;

     case DayOfWeek.Friday:

         strAlert = "Clebrating";

         break;

     case DayOfWeek.Saturday:

         strAlert = "Logn Drive";

         break;

    }

    return strAlert;

 }

Now you can call ToDoAlert method on any variable on constant of type DayOfWeek as shown below.

//Calling the ToDoAlert method of type DayOfWeek

DayOfWeek today = DayOfWeek.Saturday;

Console.WriteLine(today.ToDoAlert());

Console.WriteLine("---------------");

Console.WriteLine(DayOfWeek.Sunday.ToDoAlert());

Console.ReadKey();
