A developer utilized the Add Data Row activity to insert a row into a data table called "dt_Reports". However, during runtime, UiPath Studio encounters an exception, "Add Data Row: Object reference not set to an instance of an object." because the data table has not been initialized. To rectify this issue, what should the developer include in an Assign before the Add Data Row activity?

• Assign New System.Data.DataTable = dt_Reports.

• Assign dt_Reports = New System.Data.DataRow.

• Assign dt_Reports = New System.Data.DataTable.

• Assign dt_Reports = New List(Of DataRow).

Answer explanation

The correct choice is 'Assign dt_Reports = New System.Data.DataTable.' This initializes the data table before adding a row, preventing the 'Object reference not set to an instance of an object' exception.

Based on the graphic, what is the output at runtime?

• 0 0

• 0 3

• 20 23

• 2023

Answer explanation

La cadena "2023" se divide usando el carácter "2" como separador.
El método .Split("2"c) corta la cadena en cada lugar donde encuentra un "2".

Resultado:

• Antes del primer "2" → ""

• Entre los dos "2" → ""

• Después del último "2" → "3"

Por eso, el array final es: {"", "", "3"}
Y al recorrerlo con un bucle For Each, se imprimen estos tres valores en el log.
