I have 2 objects : Parent and ParentDTO :

    public class Parent
    {
        public int ParentID { get; set;}
        public string ParentCode { get; set; }
        public List<Child> ListChild { get; set; }
    }

    public class Child
    {
        public int ChildID { get; set; }
        public string ChildCode { get; set; }
    }

    public class ParentDTO
    {
        public int ParentID { get; set; }
        public string ParentCode { get; set; }
        public List<ChildDTO> ListChild { get; set; }
    }

    public class ChildDTO
    {
        public int ChildID { get; set; }
        public string ChildCode { get; set; }
    }

I want to using AutoMapper to map data from Parent object to ParentDTO object (all data in ListChild has to transfer to ListChildDTO)

Can anyone help me. Thanks

Before map modify your code like this

public class Parent
{
    public Parent()
    {
        this.ListChild = new List<Child>();
    }
    public int ParentID { get; set; }
    public string ParentCode { get; set; }
    public List<Child> ListChild { get; set; }
}

public class Child
{
    public int ChildID { get; set; }
    public string ChildCode { get; set; }
    public Parent Parent { get; set; }
}

public class ParentDTO
{
    public ParentDTO()
    {
        ListChild = new List<ChildDTO>();
    }
    public int ParentID { get; set; }
    public string ParentCode { get; set; }
    public List<ChildDTO> ListChild { get; set; }
}

public class ChildDTO
{
    public int ChildID { get; set; }
    public string ChildCode { get; set; }
    public ParentDTO ParentDTO { get; set; }
}

Then map
