How to set variable for className

1

Hi all,

I want to set a variable(string) classname,
i.e. var _className:String= “level” +2;

So i wrote,
var _class:Class = getDefinitionByName(_className) as Class;
trace(_class);

This code is written in .as file (as3).
What can i do to call the class… ?
Is this a right code i have written …?
Please help me …
