Contoh

Contoh berikut menunjukkan cara menggunakan metode ini untuk menemukan properti pada durasi, dan jenis properti tersebut, dari antrean cetak, tanpa menggunakan pantulan.

// 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()

Keterangan

Aplikasi Anda hanya UsePrinter akan memiliki akses ke antrean default, bahkan jika Anda memiliki AdministrateServer hak ke server cetak. Untuk membuka antrean dengan akses yang lebih besar, gunakan salah PrintQueue satu konstruktor yang memungkinkan Anda menentukan tingkat akses yang diinginkan.
