How get all object from List using linq to object?

Question

I need make simple "linq" request. It should be "linq to objects" request. So, I have List<G> glist and I want to get all of GW objects from this list. I want to see it in style like model.Select<G>( ... ).Where( ... ) ...

public class G : IEntity, ICloneable
{
    public virtual int Id { get; set; }
    public virtual string Name { get; set; }

    public virtual IList<GW> GWs { get; set; }

    public override string ToString()
    {
        return Name;
    }

    public object Clone()
    {
        return this.MemberwiseClone();
    }
}

public class GW: IEntity, ICloneable
{
    public virtual int Id { get; set; }
    public virtual string Name { get; set; }
    public virtual G G{ get; set; }

    public override string ToString()
    {
        return Name;
    }

    public object Clone()
    {
        return this.MemberwiseClone();
    }
}

You must write your table like this : tabe1(Id,columnName,...) and table2(Id,columnName,...) — mohsen, May 08 '16 at 09:00
If list isn't database table.so write type of g and gw and their members — mohsen, May 08 '16 at 09:04
Show the code you have written so far. Your question is not very clear. — Jeroen Heier, May 08 '16 at 10:05

You can get all gw object like below:

List<GW> ListOfGW=(from g in glist let lgw=g.GWs from gw in lgw select gw ).ToList();

`let lgw=g.GWs` is redundant. – Gert Arnold May 08 '16 at 10:36
Alternative way is using SelectMany, like here http://stackoverflow.com/questions/958949/difference-between-select-and-selectmany. Thanks you anyway. – Nikolay Chernov May 08 '16 at 13:11
