Question

public class parent
{
    public string abc { get; set; }
    public childclass pos { get; set; }
}

public class childclass
{
    public string value { get; set; }
}

I am currently reading the collection of parent class

var obj =
(from dia in parent
    select new
    {
        abc = dia.abc,
        pos = new childclass()
        {
            value = dia.pos.value
        },
    })
.ToList();

how do I read the nested class childclass using linq to object , this piece is not working

pos = new childclass()
{
    Value = dia.pos.Value
}, 

Please advise

It works perfectly, I think your problem is case sensitive

Classes:

public class Parent
{
    public string Abc { get; set; }

    public Childclass Pos { get; set; }
}

public class Childclass
{
    public string Value { get; set; }
}

Use:

var parent = new List<Parent> {                
    new Parent { Abc = "abc1", Pos = new Childclass { Value = "Value1" } },
    new Parent { Abc = "abc2", Pos = new Childclass { Value = "Value2" } }
};

var obj =(from dia in parent select new {
                abc = dia.Abc,
                pos = new Childclass()
                {
                    Value = dia.Pos.Value
                },
        }).ToList();
