c# - 在C#中调用C++ dll函数时访问冲突

调用C++ dll函数之一时，发生系统访问冲突错误。
(请参考下面的代码-在步骤int calresult = ...即。)
数组值均已适当给出。
输入的哪一部分可能导致此错误？

谢谢 !

C++代码xyz.dll:

typedef struct model_parameters_t
{
    uint16_t *Input4;
    uint16_t *Input5;
} ;

typedef struct calibration_set_s
{
    uint16_t *input1;
    uint16_t *input2;
    uint16_t input3;
    model_parameters_t model;
} calibration_t;



extern "C"
{
    uint16_t compute(calibration_t);
}

C#代码:

public struct model_parameters_t
{
    uint16_t [] Input4;
    uint16_t [] Input5;
} ;

public struct calibration_set_s
{
    uint16_t []input1;
    uint16_t []input2;
    uint16_t input3;
    model_parameters_t model;
} calibration_t;


[DllImport(@"xyz.dll", CallingConvention = CallingConvention.Cdecl, CharSet = CharSet.Ansi)]
public static extern int compute(calibration_set_s calibration_set_t);



public class trycompute
{
    calibration_set_s calibration_set_Cal_input = new calibration_set_s();
    calibration_set_Cal_input.input1= array;
    calibration_set_Cal_input.input2= array;
    calibration_set_Cal_input.input3= 12;
    calibration_set_Cal_input.model.input4 = array;
    calibration_set_Cal_input.model.input5 = array;

    int CalResult = computeHybridCalCoeffs(calibration_set_Cal_input);
}

最佳答案

声明类unsafe，使用实际的指针而不是C#中的结构内部的数组。

C#无法知道如何在struct内部封送数组，例如，数组的大小 undefined 。
