Creo二次开发：基于C++与C#混合编程实现

Creo二次开发基于C++、C#混合编程

1.创建C++动态链接库项目

2.编辑C++ 函数 代码dllmain.cpp

#include "pch.h"
#include <ProMdl.h>
#include <ProToolkit.h>
#include <ProUtil.h>
#include <ProMessage.h>
#include <windows.h>

extern "C" __declspec(dllexport) ProMdlType MdlRetrieve(char *name,ProMdlType type,ProMdl **mdl)
{
   
   
	
	mdl = NULL;
    //宽字符串转换为多字节字符串
    int bufSize = MultiByteToWideChar(CP_ACP, 0, name, -1, NULL, 0);
    wchar_t* wp = new wchar_t[bufSize];
    MultiByteToWideChar(CP_ACP, 0, name, -1, wp, bufSize);

	ProError err = ProMdlRetrieve(wp, type, *p_handle);
	return type;
}

extern "C" __declspec(dllexport) int Sub(int a,int b)
{
   
   
	int c = a+b;
	return c;
}

extern "C" int user_initialize() {
   
    return 0; }
extern "C" void user_terminate() {
   
    return; }
extern "C" int __imp_getaddrinfo() {
   
    return 0; }
extern "C" int __imp_freeaddrinfo() {
   
    return 0; }
extern "C" int __imp_getnameinfo() {
   
    return
