When we merge two identical or similar dataset objects in ADO. NET, we typically use the dataset's Merge method, which has multiple overloaded versions, and we review the merge method before introducing it, and here's how to use the merge method in MSDN: The merge method is used to consolidate two DataSet objects that are roughly similar to the schema . Merging on a client application is typi
