merge and match two csv files with .net <p>i've got two csv files that i want to merge. Basically, i've got my source file, and the second file will add information to that file using a primary key that they both share.</p> <p>I've done this using v-lookup but since this will be a weekly process, i want to automate it using vb.net or C#. any ideas?</p> <p>Thanks</p>
