CString 转 std::string

USES_CONVERSION;
    CString str = L"sldfjsl";
    CT2A xx(str);

    string ss = xx

CString、string 和char* 之间的转换总结

char*   转成CString	Ø 可以直接构造.如下:    char   *   p   =   "test";  CString   str(p);  Ø 可以用成员函数Format   如下:  char*   p   =   "test”;  CString   str;  str.Format("%s",   p);
char* 转换成string	直接从char*构造出string就可以了                                              chat* sz= "cwsasd";                                              string s1(sz);
string转换成char*	char *tp = const_cast(s1.c_str());
string转换成CString	CString str2; str2.Format(L"%s", s1.c_str());
CString 转换成char*	CString str("test"); int len=str.getLength(); char *cstr=new char[len+1]; cstr[len]=0; WideCharToMultiByte(CP_OEMCP, 0, str, -1, cstr, len, NULL, NULL);
CString 转换成string	// 方法：【先将CString转换成char*, 然后从char*构造出string】 CString t = CString(s[i]); int len=t.GetLength(); char *cstr=new char[len+1]; cstr[len]=0; WideCharToMultiByte(CP_OEMCP, 0, t, -1, cstr, len, NULL, NULL); string s1(cstr);
