I have a List of the following object :

```
public  class Item
{
    public DateTime DliveryDate { get; set; }
    public String Order { get; set; }
}

```

How can i group this `List<Item>` by Date using LINQ?

I used the following query but didn't got excepted result in a group by dates Got a List object with a junk date of 0001/1/1

```
var r = from i in Items
        group i by i.DliveryDate into s
        select s;

```
