Answer 1

like the others already mentioned its not really possible to compile c# in an eval() function. that functionality is planed for a latter release of the clr which anders demoed at the PDC.

as a diffrent solutionm, if your application is able to run on mono you can just use its eval function which can dynamicly compile c# code, just like javascript. it is basicly already doing what .net will be able to do in a year or two.

as an alternative if you cant use mono you could write the part that does the string manipulation in ironruby which has eval(). the rest of your code wont even know you are using ruby for that class/assambly.

the link you posted in the update looks pretty complicated for such a simple use case. using ironruby all you would have to do is write the MyDynamicEvalClass something like this:

class MyDynamicEvalClass
  def eval(someString,transformString)
    eval(someString,transformString)
  end
end

and replacing "ManipulationSetting" with some ruby code that returns a new string
