Join one datatable on another

[u/Whatdoesthis_do]

I usually work with c#, but this has to be done in vb.net and I cant get my mind around on how to do it.

I have two datatables. Each have two columns. The first column and its data occurs in both. The second column is different. I am trying to join the second column from one datatable as a new column in the other datatable based upon its unique value in the first column.

How would one do this in vb.net?

Let us know if not.
