WPF에서 프린터 이름과 포트 이름을 얻으려면 어떻게해야합니까?

Question

저는 WPF를 처음 사용합니다. 프린터 이름과 포트 (현재 시스템에 연결된 포트)를 콤보 박스에 추가하고 싶습니다.

누군가 간단한 솔루션을 보여줄 수 있습니까?

Answer 1

.net의 일부인 System.Management dll을 사용할 수 있습니다.

using System.Management; 

ManagementObjectSearcher printers= new ManagementObjectSearcher("Select Name from Win32_Printer"); 

foreach (ManagementObject printer in printers.Get()) 
    Console.WriteLine("Name: {0}", printer.GetPropertyValue("Name")); 

다음과 같은 정보를 사용할 수 있습니다 단지 이름보다 더 많은 정보를 원한다면

class Win32_Printer : CIM_Printer 
{ 
    uint32 Attributes; 
    uint16 Availability; 
    string AvailableJobSheets[]; 
    uint32 AveragePagesPerMinute; 
    uint16 Capabilities[]; 
    string CapabilityDescriptions[]; 
    string Caption; 
    string CharSetsSupported[]; 
    string Comment; 
    uint32 ConfigManagerErrorCode; 
    boolean ConfigManagerUserConfig; 
    string CreationClassName; 
    uint16 CurrentCapabilities[]; 
    string CurrentCharSet; 
    uint16 CurrentLanguage; 
    string CurrentMimeType; 
    string CurrentNaturalLanguage; 
    string CurrentPaperType; 
    boolean Default; 
    uint16 DefaultCapabilities[]; 
    uint32 DefaultCopies; 
    uint16 DefaultLanguage; 
    string DefaultMimeType; 
    uint32 DefaultNumberUp; 
    string DefaultPaperType; 
    uint32 DefaultPriority; 
    string Description; 
    uint16 DetectedErrorState; 
    string DeviceID; 
    boolean Direct; 
    boolean DoCompleteFirst; 
    string DriverName; 
    boolean EnableBIDI; 
    boolean EnableDevQueryPrint; 
    boolean ErrorCleared; 
    string ErrorDescription; 
    string ErrorInformation[]; 
    uint16 ExtendedDetectedErrorState; 
    uint16 ExtendedPrinterStatus; 
    boolean Hidden; 
    uint32 HorizontalResolution; 
    datetime InstallDate; 
    uint32 JobCountSinceLastReset; 
    boolean KeepPrintedJobs; 
    uint16 LanguagesSupported[]; 
    uint32 LastErrorCode; 
    boolean Local; 
    string Location; 
    uint16 MarkingTechnology; 
    uint32 MaxCopies; 
    uint32 MaxNumberUp; 
    uint32 MaxSizeSupported; 
    string MimeTypesSupported[]; 
    string Name; 
    string NaturalLanguagesSupported[]; 
    boolean Network; 
    uint16 PaperSizesSupported[]; 
    string PaperTypesAvailable[]; 
    string Parameters; 
    string PNPDeviceID; 
    string PortName; 
    uint16 PowerManagementCapabilities[]; 
    boolean PowerManagementSupported; 
    string PrinterPaperNames[]; 
    uint32 PrinterState; 
    uint16 PrinterStatus; 
    string PrintJobDataType; 
    string PrintProcessor; 
    uint32 Priority; 
    boolean Published; 
    boolean Queued; 
    boolean RawOnly; 
    string SeparatorFile; 
    string ServerName; 
    boolean Shared; 
    string ShareName; 
    boolean SpoolEnabled; 
    datetime StartTime; 
    string Status; 
    uint16 StatusInfo; 
    string SystemCreationClassName; 
    string SystemName; 
    datetime TimeOfLastReset; 
    datetime UntilTime; 
    uint32 VerticalResolution; 
    boolean WorkOffline; 
}; 

편집 (here에서 촬영합니다.) : 나는 단계별로 갈거야이 대답을 이해하는 데 도움합니다 . (나는 빈에서 시작합니다, 새로운 WPF 응용 프로그램이 PrinterDisplay라고 확인 생성)

다음을 선택합니다 : 오른쪽

2 "참조 추가"를 선택 SolutionExplorer 창에서 참조 항목을 클릭합니다. NET 탭과 라이브러리 System.Mamagement를 검색하여 선택 (보도를 확인!)

3 : MainWindow.cs

      get { return (ObservableCollection<SystemPrinter>)GetValue(PrintersProperty); } 
      set { SetValue(PrintersProperty, value); } 
     } 
     public static readonly DependencyProperty PrintersProperty = DependencyProperty.Register("Printers", typeof(ObservableCollection<SystemPrinter>), typeof(MainWindow), new UIPropertyMetadata(null)); 

     public MainWindow() 
     { 
      InitializeComponent(); 

      Printers = new ObservableCollection<SystemPrinter>(); 
      ManagementObjectSearcher printers = new ManagementObjectSearcher("Select Name, PortName from Win32_Printer"); 
      foreach (ManagementObject printer in printers.Get()) 
       this.Printers.Add(new SystemPrinter() 
       { 
        Name = (string)printer.GetPropertyValue("Name"), 
        Port = (string)printer.GetPropertyValue("PortName"), 
       }); 
     } 
    } 

    public class SystemPrinter 
    { 
     public string Name { get; set; } 
     public string Port { get; set; } 
    } 
} 

4에이 코드를 붙여 넣습니다 MainWindow.xam
