creating a backup copy of a datatable
Posted on 2013-01-30
hi -- i'm using vs2010 and .net 4.
i'm trying to create a backup copy of a data table that can be used in the application to compare changes from the working copy to the backup copy. it appears that most of the methods available (clone and copy) create a new pointer to the original datatable - so that when modifications are made, the "backup" reflects the modifications. i've tried this a couple different ways, but they all seem to do the same thing (ie create a pointer to the same data). i've tried using item array to copy the data, but i get the same results. how do i create the backup version so that it is indeed a copy and not a pointer? my code is below:
// Create a backup copy of the DtChannelSet
backupChannelSet = uc.DtChannelSet.Clone();
foreach (DataRow drs in uc.DtChannelSet.Rows)
