Accessing Session object inside an Asp Core 2 View

Question

I want to show Session in view. Is that possible? I try with this in my view

<div class="content-header col-xs-12">
   <h1>Welcome, @HttpContext.Session.GetString("userLoggedName")</h1>
</div>

But i get an error

Severity Code Description Project File Line Suppression State Error CS0120 An object reference is required for the non-static field, method, or property 'HttpContext.Session'

Any help, i will appreciate it. Thanks

You can inject IHttpContextAccessor implementation to your view and use it to get the Session object

@using Microsoft.AspNetCore.Http
@inject IHttpContextAccessor HttpContextAccessor
<h1>@HttpContextAccessor.HttpContext.Session.GetString("userLoggedName")</h1>

Assuming you already have everything setup for enabling session in the Startup class.

public void ConfigureServices(IServiceCollection services)
{
    services.AddSession(s => s.IdleTimeout = TimeSpan.FromMinutes(30));
    services.AddMvc();
}
public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
    app.UseSession();  // This line is needed

    app.UseMvc(routes =>
    {
        routes.MapRoute(
            name: "default",
            template: "{controller=Home}/{action=Index}/{id?}");

    });
}
