ADO.NET对象的构造(5)_DataRow(续)

    For Each t In ds.Tables

       For Each r In t.Rows

          For Each c In t.Columns

             If Not r.IsNull(c) Then Console.WriteLine(r(c).ToString())

          Next c

       Next r

     Next t

 End Sub

n          Overloads Public Overridable Function Add(ByVal values() As Object) As DataRow’ 如果在 ColumnChanging 或 RowChanging 事件过程中生成异常，则也可发生异常。如果发生异常，则不向表中添加行。

n          Overloads Public Sub Add(ByVal row As DataRow)’ 如果用户在 RowChanging 事件中生成异常，则生成异常。如果发生异常，则不向表中添加行。

示例

Private Sub AddRow(ByVal myTable As DataTable)

    Dim rc As DataRowCollection= myTable.Rows

    Dim myNewRow As DataRow

    Dim rowVals(1) As Object

    rowVals(0) = "hello"

    rowVals(1) = "world"

    myNewRow = rc.Add(rowVals)

    newRow = myTable.NewRow()

    newRow(0) = "hello"

    newRow(1) = "world"

    rc.Add(newRow)

 End Sub
