i have a following collection
ReadOnlyDictionary<string, ReadOnlyCollection<DimensionValue>> byVal =
items.ByValues;

which i am looping as follows to obtain the values
foreach (KeyValuePair<string,
ReadOnlyCollection<DimensionValue>> pair in byVal )
{
foreach (Values vals in pair.Value)
{
ddlBrandsList.Items.Add(new ListItem(vals.Name));
}
}

how can i query the collections to obtain the list of vals (values)?

thanks

It's not clear to me exactly what you want the output to be. Could you
give more details, and preferrably some sample data (both input and
desired output)?

Something like this should work:

ddlBrandsList.Items.AddRange(
from x in byVal
select x.Value.Select(dv => new ListItem(dv.Name)).ToArray()
);

Or, if you'd rather the pure LINQ way:
from x in byVal
select x.Value into vals
from val in vals
select new ListItem(val.Name)
