Hi, I use .Net Core 3.1 From Controller "Order" View "Index" I want to create a button this button redirect me to an other controller "Invoice" View "Create" Create New Invoice Problem : I want to get the Pk when i call the method Create public IActionResult Create( int someId) { //here i want to get the Pk return View(); }

use below code to get SomeId in Controller's Action "/Invoices/Create?SomeId=@item.Pk" class = "Button" >Create New Invoice public IActionResult Create( int someId) { //here i want to get the Pk return View(); }

If you mean that Id can be null then use nullable type in Action , use '?' symbol to make integer nullable "/Invoices/Create?SomeId=@item.Pk" class = "Button" >Create New Invoice public IActionResult Create( int ? someId) { //here i want to get the Pk return View(); }
