Linq query for Asp.net

System.Linq.IQueryable<CustomerProfile> query = 
    from usr in context.customer_profiles
    where usr.cust_email == LoginID
    select new CustomerProfile
    {
        NAME = usr.cust_name,
        CONTACT = usr.cust_contact,
        EMAILID = usr.cust_email,
        LOCATION = usr.cust_location,
        SERVICELOCATION=usr.cust_service_location,
        FAXNO=usr.cust_fax_no,
        FIRMNAME = usr.cust_firm_name,
        FIRMADDRESS = usr.cust_firm_address,
        DATEESTABLISHED = Convert.ToDateTime(((DateTime?)usr.date_of_established)),
        SIGNATURE = usr.cust_signature,
        LOGO =  usr.logo,
    };

On the next line, I get a message that "the specified cast is invalid." How can i fix this?

return query.ToList().FirstOrDefault();

You are comparing customer email with the login ID of your request. I assume that this will cause a casting problem if it does not return the correct results.

And use implicit listing (var), not IQueryable

Try this and then return the request. Sorry for the formatting, this gave me the blues.

        CustomerProfile query =
         (from usr in context.customer_profiles
          where usr.cust_email == LoginID
          select new
          {
              NAME = usr.cust_name,
              CONTACT = usr.cust_contact,
              EMAILID = usr.cust_email,
              LOCATION = usr.cust_location,
              SERVICELOCATION = usr.cust_service_location,
              FAXNO = usr.cust_fax_no,
              FIRMNAME = usr.cust_firm_name,
              FIRMADDRESS = usr.cust_firm_address,
              DATEESTABLISHED = Convert.ToDateTime(((DateTime?)usr.date_of_established)),
              SIGNATURE = usr.cust_signature,
              LOGO = usr.logo,
          }).FirstOrDefault();
