DataTable.AcceptChanges Metoda

Definice

Potvrdí všechny změny provedené v této tabulce od posledního volání AcceptChanges().Commits all the changes made to this table since the last time AcceptChanges() was called.

public:
 void AcceptChanges();
public void AcceptChanges ();
member this.AcceptChanges : unit -> unit
Public Sub AcceptChanges ()

Příklady

V následujícím příkladu jsou všechny chyby v tabulce.The following example tests each table for errors. Pokud lze chyby tabulky sjednotit (předáním do nedefinované funkce), je volána AcceptChanges. v opačném případě je zavolána RejectChanges.If the table's errors can be reconciled (by passing it to an undefined function), AcceptChanges is called; otherwise, RejectChanges is called.

   private void AcceptOrReject(DataTable table)
   {
       // If there are errors, try to reconcile.
       if(table.HasErrors)
       { 
           if(Reconcile(table))
           {
               // Fixed all errors.
               table.AcceptChanges();
           }
           else
           {
               // Couldn'table fix all errors.
               table.RejectChanges();
           }
       }
       else
       {
           // If no errors, AcceptChanges.
           table.AcceptChanges();
       }
   }

   private bool Reconcile(DataTable thisTable)
   {
       foreach(DataRow row in thisTable.Rows)
       {
           //Insert code to try to reconcile error.

           // If there are still errors return immediately
           // since the caller rejects all changes upon error.
           if(row.HasErrors)
               return false;
       }
       return true;
   }
Private Sub AcceptOrReject(table As DataTable)
    ' If there are errors, try to reconcile.
        If (table.HasErrors) Then
            If (Reconcile(table)) Then
                ' Fixed all errors.
                table.AcceptChanges()
            Else
                ' Couldn'table fix all errors.
                table.RejectChanges()
            End If
        Else
            ' If no errors, AcceptChanges.
            table.AcceptChanges()
        End If
 End Sub
 
Private Function Reconcile(thisTable As DataTable) As Boolean
    Dim row As DataRow
    For Each row in thisTable.Rows
       'Insert code to try to reconcile error.

       ' If there are still errors return immediately
       ' since the caller rejects all changes upon error.
       If row.HasErrors Then
           Reconcile = False
           Exit Function
       End If
    Next row
    Reconcile = True
 End Function

Poznámky

Když se zavolá AcceptChanges, všechny objekty DataRow ještě v režimu úprav úspěšně ukončí své úpravy.When AcceptChanges is called, any DataRow object still in edit mode successfully ends its edits. DataRowState se změní také: všechny Added a Modified řádky se přestanou Unchangeda Deleted řádky se odeberou.The DataRowState also changes: all Added and Modified rows become Unchanged, and Deleted rows are removed.

Metoda AcceptChanges je obecně volána na DataTable poté, co se pokusíte aktualizovat DataSet pomocí metody DbDataAdapter.Update.The AcceptChanges method is generally called on a DataTable after you attempt to update the DataSet using the DbDataAdapter.Update method.
