c++ - LPTSTR + CFile 写入问题

Question

我正在尝试从 CListBox 读取项目并使用 CFile 写入文件。

这是我的代码

int count = m_lstSelectedItems.GetCount();

CFile cfile_object;
cfile_object.Open( L"C:\\temp.txt",  CFile::modeCreate|CFile::modeReadWrite);

for(int i=0; i<count; ++i)
{       
    int n;
    LPTSTR s2 = new TCHAR[256];
    memset(s2, 0, 256);

    n = m_lstSelectedItems.GetTextLen(i);       
    m_lstSelectedItems.GetText(i, s2);

    cfile_object.Write (s2, n);     
    cfile_object.Write("\n",2);

    delete[] s2;
}

cfile_object.Close();

但我得到了这些数据

 F:\Programs\Test\SelectDialo੧䘀㨀尀倀爀漀最爀愀洀猀尀吀攀猀琀尀匀攀氀攀挀琀䐀椀愀氀漀最开

获得正确数据的任何建议。

谢谢

能够使用CT2CA函数解决它

int n;
CString str;

n = m_lstSelectedItems.GetTextLen(i);
m_lstSelectedItems.GetText(i,str);

CT2CA outputString(str, CP_UTF8);
cfile_object.Write(outputString, ::strlen(outputString));
cfile_object.Write("\n",1);
