I'm looking for a simple way to make a clone of a DataRow. Kind of like taking a snapshot of that Row and saving it. The values of original Row are then free to change but we still have another saved copy which doesn't change. Is this the correct way to do it?

DataRow Source, Destination;
// Assume we create some columns and fill them with values
Destination.ItemArray = Source.ItemArray;

Will this just set Snapshot's ItemArray reference to point to the one in Source or does it actually make a separate copy? Should I do this instead?

Destination.ItemArray = Source.ItemArray.Clone();

EDIT: I don't think the second code snippet actually compiles.

You can use ImportRow method to copy Row from DataTable to DataTable with the same schema:

var row = SourceTable.Rows[RowNum];
DestinationTable.ImportRow(row);

Update:

With your new Edit, I believe:

var desRow = dataTable.NewRow();
var sourceRow = dataTable.Rows[rowNum];
desRow.ItemArray = sourceRow.ItemArray.Clone() as object[];

will work
