This seems like it should be fairly easy, but I can't get the syntax down.

When I request /Years/1956, I want the title to render as 1956; for /Years/1957, I want to see 1957, etc.

Years.cshtml

@page "{Year:min(1956):max(2022)?}"
@model Alpha.Pages.YearsModel

@{
    ViewData["Title"] = "@Year";
}

Years.cshtml.cs

using Microsoft.AspNetCore.Mvc;
using Microsoft.AspNetCore.Mvc.RazorPages;

namespace Alpha.Pages {
    public class YearsModel : PageModel {
        public IActionResult OnGet(string Year) {
            if (@Year is null)
                return new RedirectToPageResult("Index");
            else
                return new PageResult();
        }
    }
}

I have a suggestion like below:

1. Inside the Razor PageModel class, set the public property Year.

     public class YearsModel : PageModel
       {
           public string Year { get; set; }
           public IActionResult OnGet(string Year)
           {
               if (@Year is null)
                   return new RedirectToPageResult("Index");
               else              
                   this.Year = Year;
               return new PageResult();
           }
       }
   

2. Then inside the Razor HTML Page, the public property Year is accessed from the Razor PageModel class and displayed.

  @page "{Year:min(1956):max(2022)?}"
  @model Alpha.Pages.YearsModel
  
  @{
      ViewData["Title"] = @Model.Year;
  }
