读写txt文件 中文乱码

读取txt文件中的内容放如cstring变量中

读取txt文件中一行数据

 CString filePath;
 CStdioFile file;
//打开文件
  if(!file.Open(filePath,CFile::modeRead))
{
   ::AfxMessageBox(_T("文件打开失败！"));
   return;
}
//读取文件内容
CString strText = _T(" ");
file.ReadString(strText));
//关闭文件
file.Close();

读取txt文件中内容

 

CStdioFile file;
if (PathFileExists(m_iniPath))
{
    file.Open(m_iniPath, CFile::modeRead);
    CString sS = _T("");
    while (file.ReadString(sS))
    {
        //中文乱码   
        ReadStringCharToUnicode(sS);
    }
    file.Close();
}    

//中文乱码
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, '\0', str.GetLength());

int i;
for (i = 0; i < str.GetLength(); i++)
{
szBuf[i] = (char)str.GetAt(i);
}
szBuf[i] = '\0';//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, '\0', 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;
}
