Using SqlParameter to create Order By clause

Question

I am trying to move all of my references to variables in SQL statements to the SqlParameter class however for some reason this query fails.

string orderBy =

I found an example how to do this here

you can define different sort orders in a CASE-structure and execute them appropriately to your variable value:

  SELECT CompanyName,
         ContactName,
         ContactTitle

    FROM Customers

ORDER BY CASE WHEN @SortOrder = 1 THEN CompanyName
              WHEN @SortOrder = 2 THEN ContactName
         ELSE ContactTitle

I didn't test it myself but it could work. You can give it a try. An obvious disadvantage is that you have to code all the order-by statements.
