C#, JavaScript, ASP.NET, which programs you used most? specific?
Most? Hmmmmmmmmmm plsql maybe, although its hard to say, every environment is different.
I've worked on Java, .net, PHP, C#/VB .net, ActionScript.
Then there's work on XML technologies XSLT, SOAP, REST...........
IDEs like Visual Studio, Forms/Reports Developer (6i and 10g), Eclipse, Flash Builder.......
DBMS like SQL Server (2000, 2005, 2008), Oracle 8i, 10g, 11g, MySQL
Basically anything that the job required... Tools are tools, they don't matter after a certain time. I like to work on projects of some complexity.
