I\'m very low experienced with Expressions in .NET, that\'s why I rather ask you guys. How should I - see comment below:

using P = Myclass;

you might want to take a wee look at the Predicatebuilder:

http://www.albahari.com/nutshell/predicatebuilder.aspx

the Predicatebuilder allows you to run up some very powerful expressions (AND/OR/NOT etc, etc) in a very clean and easy to understand way. For simple expressions, I do of course just roll them from scratch and apply but for the complex stuff...

I'm quite a fan of it :)
