Item[string] Indexer
The Item[string] indexer allows you to get or set the current value
of a data row column by its name. This indexer provides convenient access
to row values using array-like syntax.
Reading a value using the indexer returns null if the specified
column does not exist or if the stored value is null.
Writing a value using the indexer updates the row value and may change the
row’s DataRowState. If the row is in the Unchanged state,
assigning a different value causes the framework to capture original values
and mark the row as Modified.

// 1. Create an empty data set
IDataSet dataSet = DataSetFactory.CreateDataSet();
// 2. Create an empty data table
IDataTable departmentDataTable = dataSet.AddNewTable("Department");
departmentDataTable.AddColumn("Id", DataTypeNames.INT32);
departmentDataTable.AddColumn("Name", DataTypeNames.STRING);
// 3. Create a new row by AddNewRow method on data table, the row state is Added
IDataRow departmentDataRow = departmentDataTable.AddNewRow();
// 4. Assign value using the indexer
departmentDataRow["Name"] = "Emergency";
// 5. Read value using the indexer
object? departmentName = departmentDataRow["Name"];
// 6. Call AcceptChanges method to set row state into Unchanged
departmentDataRow.AcceptChanges();
// 7. Modify value using the indexer to put row into Modified state
