Can Array Lists Store a collection of arrays?

Question

I am trying to create a data class that retrieves records from a SQL database. I would like to be able to retrieve the array list data from multiple other forms and reports.  Each record can have as many as 32 items of various data types.

 

For example the Sales line detail records for one invoice. The number of data items and types is fixed. The number of records for any given invoice could range from 1 to 125, or possibly more.

 

I am fairly new to C# and have avoided Array Lists till now, mostly due to Microsoft's riduclous and hoplessly confused help files on this topic. I am working with windows forms desktop application. Any help on this Subject would be greatly appreciated.
