问题 I've implemented a prevalence layer for Compact Framework (including a BinaryFormatter -like serializer). I'd like to be able to serialize the compiler-generated classes that result from such things as lambdas and iterators where appropriate, so that if (for example) a lambda and its closed-over variables (that is, the display class instance) is added to an event on a serializable object, and all the closed-over variables are serializable, then the resulting object graph is still fully
