Model List

Question

Hi,
I am quite new in C# and MVC, so please excuse me , if my question is trivial or not correct. I have the following problem:

In my code, i use
public ActionResult PrintDetails(){
...
return model;
}
In some cases , i need to display the data from the model, several times. First, can you please help me, with ideias how to insert in the model multiple data, for example , it differs, only by id. Second is , how can i return something like a List of models-again, i need to display like several models, populated with different values of the data.

Thanks in advance.
