Ejemplos

En el ejemplo siguiente se crean dos DataTable objetos y se agregan a DataTableCollection de .DataSet

public static void DataTableCollectionAddRange()
{
    // create a DataSet with two tables
    DataSet dataSet = new DataSet();

    // create Customer table
    DataTable customersTable = new DataTable("Customers");
    customersTable.Columns.Add("customerId",
        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();
    }
}

Public Sub DataTableCollectionAddRange()
    ' create a DataSet with two tables
    Dim dataSet As New DataSet()

    ' create Customer table
    Dim customersTable As New DataTable("Customers")
    customersTable.Columns.Add("customerId", _
           Type.GetType("System.Int32")).AutoIncrement = True
    customersTable.Columns.Add("name", Type.GetType("System.String"))
    customersTable.PrimaryKey = New DataColumn() _
           {customersTable.Columns("customerId")}

    ' create Orders table
    Dim ordersTable As New DataTable("Orders")
    ordersTable.Columns.Add("orderId", _
           Type.GetType("System.Int32")).AutoIncrement = True
    ordersTable.Columns.Add("customerId", _
           Type.GetType("System.Int32"))
    ordersTable.Columns.Add("amount", _
           Type.GetType("System.Double"))
    ordersTable.PrimaryKey = New DataColumn() _
           {ordersTable.Columns("orderId")}

    dataSet.Tables.AddRange(New DataTable() {customersTable, ordersTable})

    ' print the tables and their columns
    Dim table As DataTable
    Dim column As DataColumn
    For Each table In dataSet.Tables
        Console.WriteLine(table.TableName)
        For Each column In table.Columns
            Console.Write("{0}" & vbTab, column.ColumnName)
        Next
        Console.WriteLine()
    Next
