Exemples

L’exemple suivant crée d’abord un DataTable nouveau avec une colonne, puis crée un seul DataRow.The following example first creates a new DataTable with one column, and then creates a single DataRow. Lors de DataRow la création, de l’ajout, de la modification et RowState de la suppression du, son est imprimé.As the DataRow is created, added, modified, and deleted, its RowState is printed.

   private void DemonstrateAcceptChanges()
   {
       //Run a function to create a DataTable with one column.
       DataTable table = MakeTable();
       DataRow row;

       // Create a new DataRow.
       row = table.NewRow();
       // Detached row.
       Console.WriteLine("New Row " + row.RowState);

       table.Rows.Add(row);
       // New row.
       Console.WriteLine("AddRow " + row.RowState);

       table.AcceptChanges();
       // Unchanged row.
       Console.WriteLine("AcceptChanges " + row.RowState);

       row["FirstName"] = "Scott";
       // Modified row.
       Console.WriteLine("Modified " + row.RowState);

       row.Delete();
       // Deleted row.
       Console.WriteLine("Deleted " + row.RowState);
   }

   private DataTable MakeTable()
   {
       // Make a simple table with one column.
       DataTable table = new DataTable("table");
       DataColumn fnameColumn = new DataColumn(
           "FirstName", Type.GetType("System.String"));
       table.Columns.Add(fnameColumn);
       return table;
   }
Private Sub DemonstrateAcceptChanges()
    ' Run a function to create a DataTable with one column.
    Dim table As DataTable = MakeTable()
    Dim row As DataRow 
 
    ' Create a new DataRow.
    row = table.NewRow()
    ' Detached row.
    Console.WriteLine("New Row " & row.RowState)
 
    table.Rows.Add(row)
    ' New row.
    Console.WriteLine("AddRow " & row.RowState)
 
    table.AcceptChanges()
    ' Unchanged row.
    Console.WriteLine("AcceptChanges " & row.RowState)
 
    row("FirstName") = "Scott"
    ' Modified row.
    Console.WriteLine("Modified " & row.RowState)
 
    row.Delete()
    ' Deleted row.
    Console.WriteLine("Deleted " & row.RowState)
 End Sub
 
 Private Function MakeTable()As DataTable
    ' Make a simple table with one column.
    Dim table As New DataTable("table")
    Dim fnameColumn As New DataColumn( _
        "FirstName", Type.GetType("System.String"))
    table.Columns.Add(fnameColumn)
    MakeTable = table
 End Function

Remarques

Lors de l' AcceptChangesappel de EndEdit , la méthode est implicitement appelée pour mettre fin à toutes les modifications.When invoking AcceptChanges, the EndEdit method is implicitly called to end any edits. Si le RowState de la ligne a été ajouté ou modifié, RowState le devient inchangé.If the RowState of the row was Added or Modified, the RowState becomes Unchanged. RowState Si a été supprimé, la ligne est supprimée.If the RowState was Deleted, the row is removed.

Pour plus d’informations, consultez la méthode BeginEdit.See the BeginEdit method for more information.

La DataTable classe a également une AcceptChanges méthode qui affecte les modifications apportées à la table entière.The DataTable class also has an AcceptChanges method which affects changes made to the whole table. Pour plus d’informations et pour obtenir un exemple de code qui montre comment accepter et refuser des modifications apportées à des lignes de données individuelles, consultez AcceptChanges et RejectChanges.For more information and a code example that demonstrates how to accept and reject changes to individual data rows, see AcceptChanges and RejectChanges.
