Below is a demo to use session to pass the string to appear in _layout page in every page , you can refer to it.
1.Register IHttpContextAccessor and session in Program.cs
builder.Services.AddSession(); builder.Services.AddHttpContextAccessor(); ... app.UseSession(); 2.In the controller, set a session variable:
HttpContext.Session.SetString("Photo", "p1"); 3.In _layout.cshtml, inject IHttpContextAccessor implementation and use it to get the HttpContext and Session object from that.
@using Microsoft.AspNetCore.Http @inject IHttpContextAccessor HttpContextAccessor ... @HttpContextAccessor.HttpContext.Session.GetString("Photo") result:
