Retrieving info from database

Question

I'm going to retrieve information from a database using LINQ but I don't know why I'm getting this error:

Invalid object name 'Retriveinfos'.

My class is here:

[Table (Name="Retriveinfos")]
public class Retriveinfo
{
        [Column]
        public string Name { get; set; }
        [Column]
        public string LastName { get; set; }
        [Column(IsPrimaryKey = true)]
        public int Id { get; set; }
    }

and then using this line of code to connect and retrieving information:

DataContext dcon = new DataContext(@"Data Source=.\SQLEXPRESS;AttachDbFilename=F:\Second_School_project\Review_Site\Review_Site\App_Data\ReviewDatabase.mdf;Integrated Security=True;User Instance=True");
Table<Retriveinfo> Retriveinfos = dcon.GetTable<Retriveinfo>();

var c = from d in Retriveinfos
        where d.Id == 1
        select new { d.Name, d.LastName };

foreach (var a in c)
    Response.Write(a.Name.ToString() + " " + a.LastName.ToString());

Well Retriveinfos is a table in your database not a class you may need to use something like the entity framework to create classes to represent you tables before you can do something like the above
