Exempel

I följande exempel visas hur du använder den här metoden för att identifiera egenskaperna och typerna av dessa egenskaper i en utskriftskö vid körning utan att använda reflektion.

// 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()

Kommentarer

Ditt program har endast UsePrinter åtkomst till standardkön, även om du har AdministrateServer behörighet till utskriftsservern. Om du vill öppna kön med större åtkomst använder du en av konstruktorerna PrintQueue som gör att du kan ange önskad åtkomstnivå.
