LocalPrintServer(LocalPrintServerIndexedProperty[])

Menginisialisasi instans LocalPrintServer baru kelas yang memiliki array yang ditentukan LocalPrintServerIndexedProperty .

public:
 LocalPrintServer(cli::array <System::Printing::LocalPrintServerIndexedProperty> ^ propertiesFilter);

public LocalPrintServer (System.Printing.LocalPrintServerIndexedProperty[] propertiesFilter);

new System.Printing.LocalPrintServer : System.Printing.LocalPrintServerIndexedProperty[] -> System.Printing.LocalPrintServer

Public Sub New (propertiesFilter As LocalPrintServerIndexedProperty())

Parameter

propertiesFilter

LocalPrintServerIndexedProperty[]

Array properti yang diinisialisasi konstruktor.

LocalPrintServer(PrintSystemDesiredAccess)

Menginisialisasi instans LocalPrintServer baru kelas yang memiliki yang ditentukan PrintSystemDesiredAccess.

public:
 LocalPrintServer(System::Printing::PrintSystemDesiredAccess desiredAccess);

public LocalPrintServer (System.Printing.PrintSystemDesiredAccess desiredAccess);

new System.Printing.LocalPrintServer : System.Printing.PrintSystemDesiredAccess -> System.Printing.LocalPrintServer

Public Sub New (desiredAccess As PrintSystemDesiredAccess)

Parameter

desiredAccess

PrintSystemDesiredAccess

Nilai yang menentukan jenis akses ke server cetak yang dibutuhkan aplikasi Anda.

Pengecualian

PrintServerException

desiredAccess adalah nilai yang hanya dapat diterapkan ke PrintQueue objek, bukan LocalPrintServer objek. Contohnya,UsePrinter.

Contoh

Contoh berikut menunjukkan cara menggunakan konstruktor ini dalam kode yang akan menginstal printer kedua yang berbeda dalam propertinya hanya dari printer yang ada di lokasi, port, dan status berbagi.

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)

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