使用SWIG,我需要将List和int数组作为参数传递给C ++函数。我尝试了以下代码
'''CPP接口代码
%module (directors="1") CppTestApp
%{
#include "TestClass.h"
#include "TestDataClass.h"
%}
%include <windows.i>
%include <std_list.i>
%include <std_string.i>
%include "arrays_csharp.i"
%feature("director") Base;
%include "TestClass.h"
%include "TestDataClass.h"
'''
但是我得到的参数为SWIGTYPE_p_std__listT_std__string_t&SWIGTYPE_p_double我无法将List分配给上述变量。有人可以帮助解决这个问题吗?
我获得了如何使用Swig将数组从C#传递到C ++的答案。请在下面查看
'''SWIG接口代码

CSHARP_ARRAYS(char *, string)
%typemap(imtype, inattributes="[In, global::System.Runtime.InteropServices.MarshalAs(UnmanagedType.LPArray, SizeParamIndex=0, ArraySubType=UnmanagedType.LPStr)]") char * INPUT[] "string[]"
%apply char * INPUT[] { char * argv [], char * argvqq [] }
%apply int INPUT[] { int sourceArray [] }
%apply double INPUT[] { double sourcedoubleArray [] }
%apply char INPUT[] { char chArray [] }
%apply bool INPUT[] { bool bArray [] }
%apply long INPUT[] { long lArray [] }
%apply float INPUT[] { float fArray [] }
%feature("director") Base;

'''C ++代码
class TestClass
{
public:
int times2(int sourceArray[], double sourcedoubleArray[], char* argv[], char chArray[], bool bArray[], float fArray[], long lArray[]);
};
