PrintProperty.Value Propriété

Définition

Espace de noms:

System.Printing.IndexedProperties

Assembly:

System.Printing.dll

En cas de substitution dans une classe dérivée, obtient ou définit la valeur de la propriété que l'objet représente.

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

Valeur de propriété

Object

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()
