I'm writing a `collection of anonymous type` into WPF `DataGrid.ItemsSource`. And now I want it back. How do I do this, Is it possible? 

How can I reconstruct the anonymous type?

Thanks!

EDIT

Ok. So could You say will this work?

```
if(this.AbcDataGrid.ItemsSource != null && this.XyzDataGrid.ItemsSource != null)
{
    var abcdata = (IEnumerable<dynamic>)this.AbcDataGrid.ItemsSource;
    var xyzdata = (IEnumerable<dynamic>)this.XyzDataGrid.ItemsSource;

    var d1 = abcdata.ToList().OrderByDescending(x => x.Id);
    var d2 = xyzdata.ToList().OrderByDescending(x => x.Id);

    var result = from i1 in d1
                 from i2 in d2
                 select new
                 {
                     Name  = i1.Name,
                     Group = i1.Group.ToString() + i2.Group.ToString()
                 };
} 

```

Properties `Group` and `Name` both present in anonymous type declaration.
