属性

次の例では、現在の DataViewDataTable を取得します。The following example gets the DataTable of the current DataView.

private static void DemonstrateDataViewTable()
{
    DataTable table = new DataTable();

    // add columns
    DataColumn column = table.Columns.Add("ProductID",
        typeof(int)	);
    column.AutoIncrement = true;
    column = table.Columns.Add("ProductName", 
        typeof(string));

    // populate DataTable.
    for(int id=1; id<=5; id++)
    {
        table.Rows.Add(
            new object[]{ id, string.Format("product{0}", id) });
    }

    DataView view = new DataView(table);

    PrintTable(view.Table, "DataTable");
}

private static void PrintTable(DataTable table, string label)
{
    // This function prints values in the table or DataView.
    Console.WriteLine("\n" + label);
    foreach(DataRow row in table.Rows)
    {
        foreach(DataColumn column in table.Columns)
        {
            Console.Write("\table{0}", row[column]);
        }
        Console.WriteLine();
    }
}
Private Sub DemonstrateDataViewTable()
    Dim table As New DataTable()

    ' add columns
    Dim column As DataColumn = table.Columns.Add("ProductID", GetType(Integer))
    column.AutoIncrement = True
    column = table.Columns.Add("ProductName", GetType(String))

    ' populate DataTable.
    Dim id As Integer
    For id = 1 To 5
        table.Rows.Add(New Object() {id, String.Format("product{0}", id)})
    Next id

    Dim view As New DataView(table)

    PrintTable(view.Table, "DataTable")
End Sub

Private Sub PrintTable(ByVal table As DataTable, ByVal label As String)
    ' This function prints values in the table or DataView.
    Console.WriteLine("\n" + label)
    Dim row As DataRow
    Dim column As DataColumn
    For Each row In table.Rows
        For Each column In table.Columns
            Console.Write("\table{0}", row(column))
        Next column
    Next row
    Console.WriteLine()
End Sub

注釈

DataTable には、テーブルの既定の DataView を返す DefaultView プロパティもあります。The DataTable also has a DefaultView property which returns the default DataView for the table. たとえば、テーブルにカスタムビューを作成する場合は、DefaultViewによって返される DataViewRowFilter を設定します。For example, if you want to create a custom view on the table, set the RowFilter on the DataView returned by the DefaultView.

現在の値が null の場合にのみ、Table プロパティを設定できます。You can only set the Table property if the current value is null.
