public static void DataTableCollectionAddRange()
{
// create a DataSet with two tables
DataSet dataSet = new DataSet();
// create Customer table
DataTable customersTable = new DataTable("Customers");

typeof(int)).AutoIncrement = true;
customersTable.Columns.Add("name",
typeof(string));
customersTable.PrimaryKey = new DataColumn[] { customersTable.Columns["customerId"] };
// create Orders table
DataTable ordersTable = new DataTable("Orders");
ordersTable.Columns.Add("orderId",
typeof(int)).AutoIncrement = true;
ordersTable.Columns.Add("customerId",
typeof(int));
ordersTable.Columns.Add("amount",
typeof(double));
ordersTable.PrimaryKey = new DataColumn[] { ordersTable.Columns["orderId"] };
dataSet.Tables.AddRange(new DataTable[] { customersTable, ordersTable });
// print the tables and their columns
foreach (DataTable table in dataSet.Tables)
{
Console.WriteLine(table.TableName);
foreach (DataColumn column in table.Columns)
{
Console.Write("{0}\table", column.ColumnName);
}
Console.WriteLine();
}
}
