Return anonymous type from LINQ query?

Question

In that in business logic layer, I have created a class like this:

public List SelectAllData()
{
    try
    {
        return (from obj i         


        

Answer 1

If you return RoleHasRight you need to construct it, not an anonymous type as you do now:

select new RoleHasRight
{
    obj,
    role.roleName
}).ToList();

Answer 2

You are creating a new, anonymous Type by using:

select new { obj,role.roleName}

This type has 2 properties (the rolename and the roleHasRights object). In order to be able to return the same inforamtion by the method, you need to create a class with this information, or to return a dynamic.

e.g.

public class RoleHasRightInfo {
   public string Rolename {get;set;}
   public roleHasRight Right {get;set;}

}

and create it within the linq expression like this:

select new RoleHasRightInfo(){ Right=obj,Rolename = role.roleName}

The method would then need to return a List of this new type:

public List<RoleHasRightInfo> SelectAllData() {
...
}
