Definition

Namespace:

System.Printing.IndexedProperties

Assembly:

System.Printing.dll

Ruft beim Überschreiben in einer abgeleiteten Klasse den Wert der Eigenschaft ab, die das Objekt darstellt, oder legt diesen Wert fest.

public:
 abstract property System::Object ^ Value { System::Object ^ get(); void set(System::Object ^ value); };

public abstract object Value { get; set; }

member this.Value : obj with get, set

Public MustOverride Property Value As Object

Eigenschaftswert

Object

Beispiele

Im folgenden Beispiel wird gezeigt, wie Sie diese Eigenschaft zum Laufzeittermin ermitteln und die Typen dieser Eigenschaften, eines Drucksystemobjekts, ohne Spiegelung zu verwenden.

// 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()
