ASP.NET Core MVC if statement in view

Question

ASP.NET Core MVC if statement in view

Is there a way to have an if statement change the text displayed in a field? I want to display "None" if the date field is 09/09/9999. Since date fields can't be null, I use that date to indicate no due date.

I tried this but get the error:

Cannot implicitly convert type string to System.DateTime.

Any help would be appreciated.

@if (@Convert.ToString(string.Format("{0:MM/dd/yyyy}", item.DueDate)) == "09/09/9999")
{
    item.DueDate = "None";
} else 
{
    @Convert.ToString(string.Format("{0:MM/dd/yyyy}", item.DueDate))
}

Declare it as nullable:

 public DateTime? DueDate { get; set; }        

and check in the view:

@if (item.DueDate.HasValue)
{
  @Convert.ToString(string.Format("{0:MM/dd/yyyy}", item.DueDate))  
}
else
{
    @:None
}

With this syntax if the item.DueDate is not defined the None will be displayed.
