I also noticed that the "Act" variable here seems hasn't been declared(or
declared anywhere else?). I've try building the same code and got the same
result and the "Operator '+' cannot be applied to operands of type 'string'
" error does pointing to the "Act.Trim" which should be of method call
syntax such as Act.Trim()
After change it, that error is eliminated.

I just converted this from VB and apparently I need to do something else
in C#. What is the problem with my select statement. I'm getting:
