Exempel

I följande exempel skapas ett DataTable med ett DataColumn och tio DataRow objekt. När du har raderat en rad AcceptChanges kallas metoden för att orsaka att den RowNotInTableException genereras.

private void DemonstrateRowNotInTableException()
{
    // Create a DataTable with one column and ten rows.
    DataTable table = new DataTable("NewTable");
    DataColumn column = new DataColumn("NewColumn");
    table.Columns.Add(column);

    DataRow newRow;
    for(int i = 0;i <10;i++)
    {
        newRow = table.NewRow();
        newRow["NewColumn"] = i;
        table.Rows.Add(newRow);
    }
    try
    {
        // Remove a row and invoke AcceptChanges.
        DataRow removedRow = table.Rows[9];
        removedRow.Delete();
        removedRow.AcceptChanges();
    }
    catch(System.Data.RowNotInTableException rowException)
    {
        Console.WriteLine("Row not in table");
    }
}

Private Sub DemonstrateRowNotInTableException()
    ' Create a DataTable with one column and ten rows.      
    Dim table As New DataTable("NewTable")
    Dim column As New DataColumn("NewColumn")
    table.Columns.Add(column)

    Dim newRow As DataRow
    Dim i As Integer
    For i = 0 To 9
        newRow = table.NewRow()
        newRow("NewColumn") = i
        table.Rows.Add(newRow)
    Next i

    Try
        ' Remove a row and invoke AcceptChanges.
        Dim removedRow As DataRow = table.Rows(9)
        removedRow.Delete()
        removedRow.AcceptChanges()
    
    Catch rowException As System.Data.RowNotInTableException
        Console.WriteLine("Row not in table")
    End Try
End Sub
