Question

My class is like this,

public class Person : DynamicObject
{
    public string Name { get; set; }
    public string Address { get; set; }
    Dictionary<string, object> dictionary = new Dictionary<string, object>();
    public int Count
    {
        get
        {
            return dictionary.Count;
        }
    }
    public override bool TryGetMember(GetMemberBinder binder, out object result)
    {
        string name = binder.Name;
        return dictionary.TryGetValue(name, out result);
    }
    public override bool TrySetMember(SetMemberBinder binder, object value)
    {
        dictionary[binder.Name] = value;
        return true;
    }
    public void AddProperty<TTValue>(string key, TTValue value = default(TTValue))
    {
        dictionary[key] = value;
    }
    public void AddProperty(string typeName, string key, object value = null)
    {
        Type type = Type.GetType(typeName);
        dictionary[key] = Convert.ChangeType(value, type);
    }
}

Then I’m creating objects from this class and add it to a list

dynamic p = new Person();
p.Name = "john";
p.Address = "address1";
p.AddProperty<DateTime>("BirthDate", DateTime.Now);
p.AddProperty("System.String", "Weigth", "70 kg");

List<Person> lstPerson=new List<Person>();

lstPerson.Add(p);

After add few person objects like this I bind this to a datagrid view using a binding source. But after bound to the grid view my dynamically created properties are not shown in the grid.

Answer 1

When I have a list of generic objects which need to be bound to a grid, I like to use a Linq select statement.

var dataSource = myList.Select(item=> new 
              { Name = item.Key, 
                MainAddress = item.Address.First() });
grid.DataSource = dataSource;
grid.DataBind();

Then you can use the property names you defined to access the columns.
