# Combining row with for each row

Hi

There are several rows as following:

\$sample (System.Data.Datatable)
0=>hoge
1=>fuga

and need to combine these rows above, using for each rows:

`<For each row>`
For each row in \$sample
`<Assign>`
row = row + row

but it doesn’t work and the error thrown like below
“+ operator is not defined in Type System.Data.Datatable”

I just want to get combined string value “hogefuga”

How can i resolve this with for each row activity?

Change this to row(0) = row(0).ToString + row(1).ToString
