C# Left join 2 DataTables without knowing the content of each, just the join key
Posted on 2014-01-21
I have 2 C# DataTables that I want to left join in order to create a combined DataTable.
I know the name of the column that joins the table, but nothing else, as the use imports the 2 tables at startup. The joining column is 'UPC'
1. What is a code example to join the 2 tables together to a third DataTable with all columns?
2. If there are column with the same name in each table will it be a problem for the join? If so, is there any solution?
