Answer №1

To achieve this, you can utilize format options along with Linq extension functions in the following manner.

DataTable sourceData; // assign your data source
var selectedRows = sourceData.AsEnumerable()
             .Select(row => string.Format("[{0}]", string.Join(",", row.ItemArray)));

var result = string.Format("[{0}]", string.Join(",", selectedRows.ToArray()));

For a demonstration, you can refer to this Demo

Answer №2

Super simple:

Let newArray = tableData.Rows.Cast<DataRow>().Select(r => r[0].ToString()).ToArray();
