vc++ CString、string、const char*的相互转换

环境：vs2010

1.CString转string

//第一种方式：
CString str = _T("Hello world!");
USES_CONVERSION;
std::string s(W2A(str));
//第二种方式：
CString str = _T("Hello world!");
std::string s = (CT2A)str; 

2.string转CString

CString str;
std::string s=“Hello world!“;
str=s.c_str();

3.CString转const char*

//第一种方式：（CString转char*转const char*）
CString str=_T("Hello world!");
const char* cstr;
char temp[100];
::wsprintfA(temp, "%ls",(LPCTSTR)str);
cstr = temp;     
//第二种方式：(CString 转string转const char*)
CString str = _T("Hello world!");
USES_CONVERSION;
std::string s(W2A(str));
const char* cstr = s.c_str(); 

4. const char*转CString

const char* cstr = "Hello world!";
CString str(cstr);
