MFC中，Unicode和多字节字符集下 CString和char的转化

Unicode下

CString转TCHAR

         TCHAR* szMsg = new TCHAR[wcslen(strAdbCmd)];  

         szMsg = strAdbCmd.GetBuffer(strAdbCmd.GetLength());

         strAdbCmd.ReleaseBuffer();

用完了别忘了delete []szMsg;

CString转 char*

      char * charP;

         CString strP;

         WideCharToMultiByte(CP_OEMCP,0,(LPCTSTR)strP,-1,charP,260,0,false);

char* TCHAR*转 CString

         charcstr[20]="sdaww";

        TCHAR tcstr[20]=_T("unicode");

         CString str=CString(cstr);

        CString str1=CString(tcstr);

  

CString转 int

          CString strNum=_T("");

          int value = _ttoi(static_cast<LPCTSTR>(strNum));

          或者

          int value = _ttoi(strNum);

int 转CString

          int ia=1232;

         CStringstri= stri.Format(_T("%d"),ia);

char*转wstring

          char *strSrc = "1111111";

          wstring  wsDes = (wchar_t*)strSrc;

多字节字符集下

Cstring转化为char

转化成数组：

Cstring   str="convert";

char char_str [512];

strncpy_s(char_str,(LPCTSTR)str_sum,sizeof(char_str));

转化成char指针：

char * ch_a =(char*)str.GetBuffer(str.GetLength());

char转化为Cstring

Cstring str;

char szBuff[2048];

str.Format("%s",szBuff);

CString 转 int ：

n=atoi(str);
