                 .Where(p => p.Field<string>("Customer_Code") == "1001")
                 .Select(p => new {p.Field<string>("Location"),p.Field<string>("Country")});

ERROR:

Error: Invalid anonymous type member declarator. Anonymous type members must be declared with a member assignment, simple name or member access.

Answer 1

Something like:

var query = dbContext.Customer
                     .Where(customer => customer.Customer_Code == "1001")
                     .Select(customer => new { customer.Location, customer.Country })
                     .Distinct();

The key here is the use of an anonymous type that serves as a tuple holding a customer’s location and country.

EDIT: After your edit, it looks like you are using data-tables, not LINQ to SQL / Entities.
In which case, you probably want something like:

var query = table.AsEnumerable()
                 .Where(p => p.Field<string>("Customer_Code") == "1001")
                 .Select(p => new 
                               {
                                  Location = p.Field<string>("Location"),
                                  Country = p.Field<string>("Country")
                               })
                 .Distinct();
