This pattern used to use in ASP.NET Core 2.2 or before. In Dotnet6 lot more efficient way available. For instance, LinkGenerator, IUrlHelper can do the same.
If you opt to get the redirectUrl from UrlActionContext you can follow below code snippet
If you are In Controller:
using Microsoft.AspNetCore.Mvc;
using Microsoft.AspNetCore.Mvc.Routing;
namespace DotNet6MVCWebApp.Controllers
{
public class ActionHelperController : Controller
{
private readonly LinkGenerator _linkGenerator;
public ActionHelperController(LinkGenerator linkGenerator)
{
_linkGenerator = linkGenerator;
}
public IActionResult Index()
{
UrlActionContext urlActionContext = new UrlActionContext();
urlActionContext.Controller = "Members";
urlActionContext.Action = "MemberList";
var redirectUrl = _linkGenerator.GetUriByAction(HttpContext, action: urlActionContext.Action, controller: urlActionContext.Controller, null, HttpContext.Request.Scheme);
return Redirect(redirectUrl);
}
}
}
If you are In Middleware:
public class ActionHelperMiddleware
{
private readonly RequestDelegate _next;
private readonly LinkGenerator _linkGenerator;
public ActionHelperMiddleware(RequestDelegate next, LinkGenerator linkGenerator)
{
_next = next;
_linkGenerator = linkGenerator;
}
public async Task InvokeAsync(HttpContext httpContext)
{
UrlActionContext urlActionContext = new UrlActionContext();
urlActionContext.Controller = "LoopUpload";
urlActionContext.Action = "Index";
var url = _linkGenerator.GetUriByAction(httpContext, action: urlActionContext.Action, controller: urlActionContext.Controller, null, httpContext.Request.Scheme);
await _next(httpContext);
}
}
