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:
Operator '+' cannot be applied to operands of type 'string' and 'method
group'

act.Trim is a method and therefore must have parenthesis

act.Trim should be act.Trim()

Hi Cj,

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.

Sincerely,

Steven Cheng
