How to use Lambda in LINQ select statement

Question

I am trying to select stores using a lambda function and converting the result to a SelectListItem so I can render it. However it is throwing a \"Type of Expression

Answer 1

Using Lambda expressions:

1. If we don't have a specific class to bind the result:

    var stores = context.Stores.Select(x => new { x.id, x.name, x.city }).ToList();
   

2. If we have a specific class then we need to bind the result with it:

   List stores = context.Stores.Select(x => new SelectListItem { Id = x.id, Name = x.name, City = x.city }).ToList();
   

Using simple LINQ expressions:

1. If we don't have a specific class to bind the result:

   var stores = (from a in context.Stores select new { x.id, x.name, x.city }).ToList();
   

2. If we have a specific class then we need to bind the result with it:

   List stores = (from a in context.Stores select new SelectListItem{ Id = x.id, Name = x.name, City = x.city }).ToList();
