前提：VS2010 ,MFC ,文本文件为ANSI格式。
读文件：
CString str,fileContent;
CStdioFile myFile, File;
if(myFile.Open(GeneralUtils::GetModuleDir()+_T(\mx.txt), CFile::modeRead))
{
//读取
while(myFile.ReadString(str))
{
str = str + _T("
");
ReadStringCharToUnicode(str);
fileContent = fileContent + str;
}
myFile.Close();
}
写文件：
*.h
#include <locale.h>
*.cpp
setlocale(LC_CTYPE,"chs");
myFile.Open(GeneralUtils::GetModuleDir()+_T(\mx2.txt), CFile::modeWrite | CFile::modeCreate);
myFile.WriteString(fileContent);
myFile.Close();
void ReadStringCharToUnicode(CString &str)
{
char *szBuf = new char[str.GetLength() + 1];//注意“+1”，char字符要求结束符，而CString没有
memset(szBuf, ' ',str.GetLength());
int i;
for ( i = 0 ; i < str.GetLength(); i++)
{
szBuf[i] = (char)str.GetAt(i);
}
szBuf[i] = ' ';//结束符。否则会在末尾产生乱码。
int nLen;
WCHAR *ptch;
CString strOut;
if(szBuf == NULL)
{
return ;
}
nLen = MultiByteToWideChar(CP_ACP, 0, szBuf, -1, NULL, 0);//获得需要的宽字符字节数
ptch = new WCHAR[nLen];
memset(ptch, ' ', nLen);
MultiByteToWideChar(CP_ACP, 0, szBuf, -1, ptch, nLen);
str.Format(_T("%s"), ptch);
if(NULL != ptch)
delete [] ptch;
ptch = NULL;
if(NULL != szBuf)
delete []szBuf;
szBuf = NULL;
return ;
}
