A DataRow does not necessarily belong to any table's collection of rows. This behavior occurs when the DataRow has been created but not added to the DataRowCollection. If the RowState property returns DataRowState.Detached, the row is not in any collection.
privatevoid GetTable(DataRow row)
// Get the DataTable of a DataRow
DataTable table = row.Table;
// Print the DataType of each column in the table. foreach(DataColumn column in table.Columns)
