Question

my query :

public List<Book> GetAllBook()
{
    return (from c in this.LDEntities.Book
             select new
             {
                 c.IdBook,
                 c.NameBook,
                 c.Athour
             }).ToList();
}

error :

Cannot implicitly convert type ‘AnonymousType#1’ to ‘System.Collections.Generic.List

What is the correct code?

Update: I use from Entity Framework in Layered Architectures.

Answer 1

Try this:

public List<Book> GetAllBook() {     

    var q = (from c in this.LDEntities.Book              
             select new Book() 
             { 
                 IdBook = c.IdBook, 
                 NameBook = c.NameBook, 
                 Athour = c.Athour }).ToList();     
    return (q); 
} 

In other words, create a collection of type Book, not a collection of anonymous types.
