在C＃中导入C ++ DLL AccessViolationException

Question

I use one dll write in c++ in my program C#

I have some problem, when I execute it, I have AccessViolationException for my line

XIJET_GetPrinterParameter(ID_Printer, XIJET_RESOLUTION, parametre);

Do you have some idea? The extract from documentation is

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 to the C++ doc, the method signature should be:

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

you can see the type conversion table here:

Answer 2

I have struggled with this myself, however I did find 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
