Импорт C++ DLL в C# AccessViolationException

Question

я использую одну DLL записи в C++ в моей программе C#

У меня есть некоторые проблемы, когда я исполню его, я AccessViolationException для моей линии

У вас есть идея? Выписка из документации

 
    int XIJET_GetPrinterParameter (HANDLE PrinterHandle, // as returned from open call 
    USHORT ParameterIndex, 
    PVOID pParameter, 
    USHORT HeadNumber = 0); // when applicable 
    Returns: 1 = success 
    0 = error 
    XIJET_GetPrinterParameter will return a single printer configuration parameter. ParameterIndex dictates which 
    parameter will be returned, while pParameter points to an appropriately sized memory field. Defined constants 
    for ParameterIndex are located in XIJET_API.h. The optional parameter HeadNumber should only be included 
    for head specific parameters, such as trigger offset distance. 
    For example to read the printers print queue depth setting: 
    int Success; 
    USHORT value; 
    Success = XIJET_GetPrinterParameter(printerHandle, XIJET_QUEUE_DEPTH, &value); 
    See Appendix A for list of adjustable printer parameters.

Answer 1

Accordind к документу C++, метод подпись должна быть:

public static extern int XIJET_GetPrinterParameter(IntPtr printerHandle, 
      Uint16 parameterIndex, 
      IntPtr pParameter, UInt16 headNumber);

Answer 2

Я сам боролся с этим, однако я сделал f ind a solution:

Public Declare Function XIJET_SetPrinterParameter Lib "XIJET_API" (ByVal printerHandle 
    As IntPtr, ByVal parameterIndex As UShort, ByRef pParameter As UShort, 
    ByVal HeadNumber As UShort) As Short
