LINQ request

Hi,

I have a table containing the columns CODE / DATE / PRICE / VOLUME. I want to make a request on a _listOfCode but I don't know what to put in the "where" query in the following lines. The length of the list could very from query to query. Please, can someone help me on this?

Thanks,
Kamel
