Reading data from two csv files and combining into an array

Hi all,

I have a scoured the internet in hope of some solutions, but to no avail. I would like to read data from two csv files and combine into an array - the data from one file contains node id's along with their corresponding (x, y, z) coordinates. The other csv file contains information regarding a 10 point tetrahedron, as in which node needs to be connected together in order to construct a mesh between each node (vertex). The two csv files are formatted as follows:

How would one go about constructing the code that would allow me to do this? is it best to use a dictionary in the form of:

     private List<Dictionary<string, object>> NodeList;
     private List<Dictionary<string, object>> ElementList;

Any help would be greatly appreciated!
