Exemples
L’exemple suivant montre comment utiliser cette propriété pour découvrir au moment de l’exécution les propriétés et les types de ces propriétés d’un objet système d’impression, sans utiliser la réflexion.
// Enumerate the properties, and their types, of a queue without using Reflection
LocalPrintServer localPrintServer = new LocalPrintServer();
PrintQueue defaultPrintQueue = LocalPrintServer.GetDefaultPrintQueue();
PrintPropertyDictionary printQueueProperties = defaultPrintQueue.PropertiesCollection;
Console.WriteLine("These are the properties, and their types, of {0}, a {1}", defaultPrintQueue.Name, defaultPrintQueue.GetType().ToString() +"\n");
foreach (DictionaryEntry entry in printQueueProperties)
{
PrintProperty property = (PrintProperty)entry.Value;
if (property.Value != null)
{
Console.WriteLine(property.Name + "\t(Type: {0})", property.Value.GetType().ToString());
}
}
Console.WriteLine("\n\nPress Return to continue...");
Console.ReadLine();
' Enumerate the properties, and their types, of a queue without using Reflection
Dim localPrintServer As New LocalPrintServer()
Dim defaultPrintQueue As PrintQueue = LocalPrintServer.GetDefaultPrintQueue()
Dim printQueueProperties As PrintPropertyDictionary = defaultPrintQueue.PropertiesCollection
Console.WriteLine("These are the properties, and their types, of {0}, a {1}", defaultPrintQueue.Name, defaultPrintQueue.GetType().ToString() + vbLf)
For Each entry As DictionaryEntry In printQueueProperties
Dim [property] As PrintProperty = CType(entry.Value, PrintProperty)
If [property].Value IsNot Nothing Then
Console.WriteLine([property].Name & vbTab & "(Type: {0})", [property].Value.GetType().ToString())
End If
Next entry
Console.WriteLine(vbLf & vbLf & "Press Return to continue...")
Console.ReadLine()
