(1)把 Preprocessor Definitiond写入UNICODE,_UNICODE (要选择一下默认的值这样才能改的生效)
(2)工程改成Unicode的
#ifdef _UNICODE
#define tstring std::wstring
#else
#define tstring std::string
#endif
实现过程:
readtxt.cpp:
#include "stdafx.h"
#include <stdio.h>
#include<fstream>
using namespace std;
tstring getline(FILE *stream)
{
tstring strRet;
TCHAR line[100] = {0};
while( _fgetts( line, 100, stream ) != NULL)
{
if (line[0] == 0xFEFF)//unicode 文件的头
{
strRet += &line[1];
}
else
{
strRet += line;
}
if (line[_tcslen(line)-1] == _T('\n'))
{
break;
}
}
return strRet;
}
void Trim( tstring& str , const tstring& chars =_T(" \t" ))
{
str.erase(str.find_last_not_of(chars)+1);
str.erase(0, str.find_first_not_of(chars));
}
int main(int argc,char **argv)
{
FILE *stream = NULL;
TCHAR szUserSuffix [20] = _T("E:\\1.txt");
TCHAR strQuickUser[100]={0};
if( _wfopen_s( &stream,strQuickUser, _T("rt+,ccs=UNICODE ") ) == 0 ) //用到的函数都是多字节的;
{
tstring sRead;
while (!feof(stream))
{
sRead = getline(stream);
if (sRead.empty())
{
continue;
}
else
{
int n;
n=sRead.find(_T("="));
tstring s1 = _T("");
tstring s2 = _T("");
s1=sRead.substr(0,n);
s2=sRead.substr(n+1,sRead.length());
Trim(s1);
Trim(s2);
TCHAR tstrInitial[200];
TCHAR tstrChinese[200];
