Exemples

L’exemple de code suivant obtient la BindingMemberInfo de chaque Binding sur un formulaire, puis imprime les valeurs de propriété BindingPath, BindingFieldet BindingMember de BindingMemberInfo.The following code example gets the BindingMemberInfo of each Binding on a form, and prints the BindingPath, BindingField, and BindingMember property values of BindingMemberInfo.

private:
   void PrintBindingMemberInfo()
   {
      Console::WriteLine( "\n BindingMemberInfo" );
      for each ( Control^ thisControl in this->Controls )
      {
         for each ( Binding^ thisBinding in thisControl->DataBindings )
         {
            BindingMemberInfo bInfo = thisBinding->BindingMemberInfo;
            Console::WriteLine( "\t BindingPath: {0}", bInfo.BindingPath );
            Console::WriteLine( "\t BindingField: {0}", bInfo.BindingField );
            Console::WriteLine( "\t BindingMember: {0}", bInfo.BindingMember );
            Console::WriteLine();
         }
      }
   }
private void PrintBindingMemberInfo()
{
   Console.WriteLine("\n BindingMemberInfo");
   foreach(Control thisControl in this.Controls)
   {
      foreach(Binding thisBinding in thisControl.DataBindings)
      {
         BindingMemberInfo bInfo = thisBinding.BindingMemberInfo;
         Console.WriteLine("\t BindingPath: " + bInfo.BindingPath);
         Console.WriteLine("\t BindingField: " + bInfo.BindingField);
         Console.WriteLine("\t BindingMember: " + 
         bInfo.BindingMember);
         Console.WriteLine();
      }   
   }
}
Private Sub PrintBindingMemberInfo()
   Console.WriteLine(ControlChars.Cr + " BindingMemberInfo")
   Dim thisControl As Control
   Dim thisBinding As Binding
   For Each thisControl In  Me.Controls    
      For Each thisBinding In  thisControl.DataBindings
         Dim bInfo As BindingMemberInfo =  _
         thisBinding.BindingMemberInfo
         Console.WriteLine(ControlChars.Tab + _
         " BindingPath: "  + bInfo.BindingPath)
         Console.WriteLine(ControlChars.Tab + _
         " BindingField: " + bInfo.BindingField)
         Console.WriteLine(ControlChars.Tab + _
         " BindingMember: "  + bInfo.BindingMember)
         Console.WriteLine()
      Next thisBinding
   Next thisControl
End Sub

Remarques

Le BindingField est le dernier élément trouvé dans le chemin de navigation retourné par la propriété BindingMember.The BindingField is the last item found in the navigation path returned by the BindingMember property. Par exemple, si une nouvelle Binding est créée avec un paramètre dataMember de « Customers. custToOrders. OrderDate », BindingMember retourne « OrderDate ».For example, if a new Binding is created that has a dataMember parameter of "Customers.custToOrders.OrderDate", BindingMember will return "OrderDate".
