如何使用Expression创建动态类

Question

我想做这样的事情：

Expression<Func<dynamic>> newClassExpression = //Create a new anonymous object
foreach (Expression exp in subSelector)
{
   //Create a new property into newClassExpression to affect exp.Compile().Invoke(f)
}
return newClassExpression.Compile(); //Return here the code for creation of the new class
