DataTable Sort (upper, case, status) C#

Question

I have some problem with DataTable sorting.

I have some sorts in PowerBuilder script like status_abbr A . In C# it will be status_abbr ASC . But I don't how to interpret it in C# (DataTable Sort) such sort strings as Upper(era_supp) A and case( status when 'P' then 'O' when 'Q' then 'O' else status ) A .

Maybe someone can help me?

Answer 1

Use the DataTable.CaseSensitive Property: It indicates whether string comparisons within the table are case-sensitive. In your case you want it set to False.

You can alternatively add a calculated column in your DataTable and sort by that column. The column expression contains the mapping that you need.

A third option is to use the .OrderBy method, passing a lambda expression. You need to look this up in the Internet. There are plenty of example.
