Steps: 1. Configure session in startup class services and middleware section public void ConfigureServices(IServiceCollection services) { services.AddControllersWithViews(); services.AddSession(options => { options.IdleTimeout = TimeSpan.FromMinutes(30); // Session timeout options.Cookie.HttpOnly = true; // Cookie accessible only on the server side options.Cookie.IsEssential = true; // Make the session cookie essential }); } public void Configure(IApplicationBuilder app, IWebHostEnvironment env) { app.UseRouting(); app.UseSession(); // Enable session middleware app.UseEndpoints(endpoints => { endpoints.MapControllerRoute( name: "default", pattern: "{controller=Home}/{action=Index}/{id?}"); }); } 2. Access inside the controller using Microsoft.AspNetCore.Mvc; using Microsoft.AspNetCore.Http; public class MyController : Controller { public IActionResult Index() { // Store data in session HttpContext.Session.SetString("UserName", "JohnDoe"); return View(); } public IActionResult GetUserName() { // Retrieve data from session string userName = HttpContext.Session.GetString("UserName"); if (userName != null) { return Content("User Name: " + userName); } else { return Content("User Name not found in session."); } } public IActionResult ClearSession() { // Remove specific item from session HttpContext.Session.Remove("UserName"); // Or clear entire session // HttpContext.Session.Clear(); return Content("Session data cleared."); } }

Hi Jaya Prakash, Please share error details or screen shot so I can help

Jayraj Chhaya · Answer

You can access and utilize session variables within a controller class by leveraging the Session property provided by the Controller base class. This property allows you to store and retrieve session data easily. public class HomeController : Controller { public IActionResult Index() { // Storing data in session HttpContext.Session.SetString("UserName", "JohnDoe"); // Retrieving data from session var userName = HttpContext.Session.GetString("UserName"); return View(); } }

Hello Jaya Prakash, Please refer to this thread which has a very good explanation of the mvc core application, you need to install the Nuget package for the session "Microsoft.AspNetCore.Session package", https://www.c-sharpcorner.com/blogs/session-management-in-asp-net-core-mvc public class HomeController : Controller { public IActionResult Index() { string MySessionValue = "Jaya Prakash"; HttpContext.Session.SetString("SessionKeyName", MySessionValue); } } // Access in another Controller public class TestSessionController : Controller { public IActionResult Index() { var nameFromSession = HttpContext.Session.GetString(SessionKeyName); } }
