Question

Here a great person gave a option to sort a table with a different casting

It is possible to do it in Linq2Sql?

Answer 1

This will only work client side if you dont use SQL queries as a string.

For instance (I’m just making up some fields):

(from c in db.Customers 
select c).ToList() //ToList executes the query
         .OrderBy(c => c.CreditLimit.ToString())
         .OrderBy(c => double.Parse(c.CustomerId))
         //etc

Update: It seems you need to do this server side:

context.ExecuteQuery(typeof(TestTable1), "SELECT * FROM 
TestTable1 ORDER BY CAST(Text1 as bigint)");

Use a SQL query to obtain your objects since Linq-to-SQL does not support your requirement.
