Se aplica a

LocalPrintServer(LocalPrintServerIndexedProperty[])

Inicializa una nueva instancia de la clase LocalPrintServer que tiene la matriz LocalPrintServerIndexedProperty especificada.

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())

Parámetros

propertiesFilter
LocalPrintServerIndexedProperty[]

Matriz de las propiedades que el constructor inicializa.

Se aplica a

LocalPrintServer(PrintSystemDesiredAccess)

Inicializa una nueva instancia de la clase LocalPrintServer que con la propiedad PrintSystemDesiredAccess especificada.

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)

Parámetros

desiredAccess
PrintSystemDesiredAccess

Valor que especifica el tipo de acceso al servidor de impresión que la aplicación necesita.

Excepciones

desiredAccess es un valor que sólo puede aplicarse a un objeto PrintQueue, no a un objeto LocalPrintServer. Por ejemplo, UsePrinter.

Ejemplos

En el ejemplo siguiente se muestra cómo usar este constructor en el código que instalará una segunda impresora que difiere en sus propiedades de una impresora existente solo en la ubicación, el puerto y el estado compartido.

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

// 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 ...");
