範例

下列範例示範如何使用這個類別,從現有的印表機,只在位置、埠和共用狀態中,安裝不同于其屬性的第二個印表機。The following example shows how to use this class to install a second printer that differs in its properties from an existing printer only in location, port, and shared status.

LocalPrintServer myLocalPrintServer = new LocalPrintServer(PrintSystemDesiredAccess.AdministrateServer);
PrintQueue sourcePrintQueue = myLocalPrintServer.DefaultPrintQueue;
PrintPropertyDictionary myPrintProperties = sourcePrintQueue.PropertiesCollection;

// Share the new printer using Remove/Add methods
PrintBooleanProperty shared = new PrintBooleanProperty("IsShared", true);
myPrintProperties.Remove("IsShared");
myPrintProperties.Add("IsShared", shared);

// Give the new printer its share name using SetProperty method
PrintStringProperty theShareName = new PrintStringProperty("ShareName", "\"Son of " + sourcePrintQueue.Name +"\"");
myPrintProperties.SetProperty("ShareName", theShareName);

// Specify the physical location of the new printer using Remove/Add methods
PrintStringProperty theLocation = new PrintStringProperty("Location", "the supply room");
myPrintProperties.Remove("Location");
myPrintProperties.Add("Location", theLocation);

// Specify the port for the new printer
String[] port = new String[] { "COM1:" };


// Install the new printer on the local print server
PrintQueue clonedPrinter = myLocalPrintServer.InstallPrintQueue("My clone of " + sourcePrintQueue.Name, "Xerox WCP 35 PS", port, "WinPrint", myPrintProperties);
myLocalPrintServer.Commit();

// Report outcome
Console.WriteLine("{0} in {1} has been installed and shared as {2}", clonedPrinter.Name, clonedPrinter.Location, clonedPrinter.ShareName);
Console.WriteLine("Press Return to continue ...");
Console.ReadLine();
Dim myLocalPrintServer As New LocalPrintServer(PrintSystemDesiredAccess.AdministrateServer)
Dim sourcePrintQueue As PrintQueue = myLocalPrintServer.DefaultPrintQueue
Dim myPrintProperties As PrintPropertyDictionary = sourcePrintQueue.PropertiesCollection

' Share the new printer using Remove/Add methods
Dim [shared] As New PrintBooleanProperty("IsShared", True)
myPrintProperties.Remove("IsShared")
myPrintProperties.Add("IsShared", [shared])

' Give the new printer its share name using SetProperty method
Dim theShareName As New PrintStringProperty("ShareName", """Son of " & sourcePrintQueue.Name & """")
myPrintProperties.SetProperty("ShareName", theShareName)

' Specify the physical location of the new printer using Remove/Add methods
Dim theLocation As New PrintStringProperty("Location", "the supply room")
myPrintProperties.Remove("Location")
myPrintProperties.Add("Location", theLocation)

' Specify the port for the new printer
Dim port() As String = { "COM1:" }


' Install the new printer on the local print server
Dim clonedPrinter As PrintQueue = myLocalPrintServer.InstallPrintQueue("My clone of " & sourcePrintQueue.Name, "Xerox WCP 35 PS", port, "WinPrint", myPrintProperties)
myLocalPrintServer.Commit()

' Report outcome
Console.WriteLine("{0} in {1} has been installed and shared as {2}", clonedPrinter.Name, clonedPrinter.Location, clonedPrinter.ShareName)
Console.WriteLine("Press Return to continue ...")
Console.ReadLine()

下列範例顯示如何使用這個類別,在執行時間探索列印系統物件的屬性,以及這些屬性的類型,而不使用反映。The following example shows how to use this class to discover at run time the properties, and the types of those properties, of a print system object, without using reflection.


// 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()

備註
