Can I populate Enum with For in C#?-CodePudding

I'm working with Asp.net and MVC, creating a code where the person needs to enter month and year to perform a search. I created an Enum for the months of the Year, but I can't find it "right" to create an Enum for the years, as I would have to manually populate and each year add a new value.

In my Cshtml I had done it that way

<select name="ano">

  @for (int i = DateTime.Now.Year; i > 1999; i--)
  {
    <option>@i</option>
  }
</select>

But to go to the MVC standard, I wanted to put this information in an Enum inside my Model. Can I do something similar to dynamically place the years in an Enum?

CodePudding user response：

MVC does not prescribe that everything must be a class or enum. It makes no sense to have enum members representing years.

What were you going to name them, Y2021 and then strip the Y? Or use their underlying numeric value, ignoring the label?

Just use a loop and an integer, like you do now.

To approach to MVC standarts , you don't need to create any enums, you have to create a model

public ViewModel 
{
  public int Year {get;set;}
  public List<SelectListItem> Years {get; set;}
}

and controller action

public ActionResult GetYear()
{
  var years = new List<SelectListItem>();

  for (var i = DateTime.Now.Year; i >= 1999 ; i--)
     years.Add ( new SelectListItem { Value=i.ToString(),Text=i.ToString()});

 var model=new ViewModel{ Year=2021,Years= years});

 return View(model);
}

and view GetYear.cshtml

@model ViewModel
.....
 <select class="form-control"  asp-for="@Model.Year" asp-items="@Model.Years"></select>
