You need to map the data returned into an instance of 'q ... whatever that is. Show us the structure of 'q and maybe we can help.

Hi Bill
from the question and what i have tried , its clear that he needs to assign the value from the list to a variable..
[GetRestDetails(Convert.ToInt32(lblID.Text)] this piece of code denotes that, the method will return only one Item ( ID, guessed )
and he is trying to assign the value from the Select query to a string variable which resulted in cast exception.

try this

C#

var item = BusinessLayer.restdetailsBAL.Instance.GetRestDetails(Convert.ToInt32(lblID.Text)).Select(q => new
         {
             Unit = q.Unit,
             SelPrice = q.SellPrice,
             Batch = q.Batch,
             Expiry = q.Expiry
         }).FirstOrDefault();

         if (item != null)
         {
             string unit = item.Unit;
             var SelPrice = item.SelPrice;
             var Batch = item.Batch;
             var Expiry = item.Expiry;
         }
