Beispiele

Im folgenden Codebeispiel wird die BindingMemberInfo der einzelnen Binding auf einem Formular abgerufen, und die BindingPath, BindingFieldund BindingMember-Eigenschaftswerte BindingMemberInfowerden gedruckt.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

Hinweise

Der BindingField ist das letzte Element, das in dem von der BindingMember-Eigenschaft zurückgegebenen Navigationspfad gefunden wurde.The BindingField is the last item found in the navigation path returned by the BindingMember property. Wenn z. b. eine neue Binding erstellt wird, die den dataMember Parameter "Customers. custdeorders. OrderDate" aufweist, gibt BindingMember "OrderDate" zurück.For example, if a new Binding is created that has a dataMember parameter of "Customers.custToOrders.OrderDate", BindingMember will return "OrderDate".
