Import/Export Generic List Objects

Question

I have a number of list (objects?).

For example:

private System.Collections.Generic.List<Person> Person;
this.People = new System.Collections.Generic.List<Person>();

What I'd like to do is somehow export these lists out..don't mind what format..flatfile..whatever..

And then be able to import them in "recreating" the list (object?)

Any direction would be appriciated.

Thanks,
