Binding anonymous type to Create a BindingList

Question

I am trying to create a BindingList<> from anonymous type returned by LINQ query but BindingList<> do not accept anonymous type, following is my code

var data = context.RechargeLogs.Where(t => t.Time >= DateTime.Today).
           Select(t => new 
           {
                col1 = t.Id,
                col2 = t.Compnay,
                col3 = t.SubscriptionNo,
                col4 = t.Amount,
                col5 = t.Time
           });

var tmp =  new BindingList<???>(data);

In the last line generic argument what to place ???

Answer 1

You can write an extension method:

static class MyExtensions
{
    public static BindingList<T> ToBindingList<T>(this IList<T> source)
    {
        return new BindingList<T>(source);
    }
}

and use it like this:

        var query = entities
            .Select(e => new
            {
               // construct anonymous entity here
            })
            .ToList()
            .ToBindingList();
