c#无法读取c++写的dll
代码如下：// SendSM.cpp : 定义控制台应用程序的入口点。
#include "stdafx.h"
#include "CMPPAPI.hpp"
#include "windows.h"
#include "string.h"
#include "atltime.h"
int _tmain()
{
char LogFile[100];
char str[100];
char str1[100];
char str2[100];
char *ConfigFile = "../config/sms.ini";
FILE *fplog=NULL;
CTime theTime = CTime::GetCurrentTime();
CString strtime = theTime.Format( "%m/%d %H:%M:%S" );
GetPrivateProfileString("LOG","logfile","../config/smstemp.log",LogFile, 100, ConfigFile);
if((fplog = fopen(LogFile, "a+")) == NULL) {
fprintf(stderr, "\tSendSM Can't open Log file: %s\n",LogFile);
exit(1);
}
if(getenv("NX_NTF_VOICE_PHONE")!=NULL)
{
fprintf(fplog, "<person><time1>%s</time1> <phone>%s</phone> \n", strtime,memcpy(str , getenv("NX_NTF_VOICE_PHONE") , strlen(getenv("NX_NTF_VOICE_PHONE")) + 1));
}
else {
fprintf(fplog, "<person><rtime>%s</rtime><error>Parameter Error!!!No SmsPhone En_Variable!!!</error></person>\n", strtime);
exit(1);
}
if(getenv( "NX_NTF_SUMMARY" )!=NULL){
fprintf(fplog, "<time2>%s</time2> <summary>%s</summary> \n", strtime,memcpy(str1 , getenv("NX_NTF_SUMMARY") , strlen(getenv("NX_NTF_SUMMARY")) + 1));
}
else {
//printf("\n\nNo Msgtitle En_Variable!!!\n");
fprintf(fplog, "<person><rtime>%s</rtime><error>Parameter Error!!!No Msgtitle En_Variable!!!</error></person>\n", strtime);
exit(1);
}
if(getenv( "NX_NTF_MESSAGE" )!=NULL){
fprintf(fplog, "<time3>%s</time3> <message>%s</message></person> \n", strtime,memcpy(str2 , getenv("NX_NTF_MESSAGE") , strlen(getenv("NX_NTF_MESSAGE")) + 1));
}
else{
//printf("\n\nNo Msgbody En_Variable!!!\n");
fprintf(fplog, "<person><rtime>%s</rtime><error>Parameter Error!!!No Msgbody En_Variable!!!</error></person>\n", strtime);
exit(1);
}
fclose(fplog);
return 0;
}
问题：代码没有什么问题，关键dll输出以后，c#无法找到这个方法，我用类写过这个方法，也不太行，希望各位高手帮把给我~~ --------------------编程问答-------------------- 没人知道么？失望 --------------------编程问答-------------------- 看看是不是少个模块定义文件 def
; sss.def : 声明 DLL 的模块参数。
LIBRARY "sss"
EXPORTS
; 此处可以是显式导出
--------------------编程问答-------------------- 显示导出什么？
补充：.NET技术 , VC.NET
