First, this is not a question. Secondly, this would-be a question makes no sense; I explain it in my answer; please see.

Solution 1

The whole idea makes no sense. You probably do not completely understand relational model. There is no such thing as first row or second row. Row ordering is not defined from the standpoint of a SQL user (or a relationship database client in general).

Ordering is the internal issue of the database storage, which is abstracted from the user. And even internally, it is not unambiguously defined. Rather, you can speak about indexing. Please see:
http://en.wikipedia.org/wiki/Database_index[^].

An exact copy of a row to another row of the same table is also not a consistent operation which would make sense, because a primary key of a table is maintained unique. An attempt to add a record withe the same primary key would be failed by a RDBMS. Please see:
http://en.wikipedia.org/wiki/Primary_key[^].

Again, it makes no sense.

Solution 2

Each DataRow has an ItemArray property which actually holds the data, so you just need to use something like this:-

C#

table.Rows.Add(table.Rows[0].ItemArray);
