C++基本语法：CString string char*之间转换

1、CString to char*

  1) pc = str.GetBuffer(str.GetLength() + 1);

     Str.ReleaseBuffer();

 2) pc = (SLPSTR)(LPCTSTR)str;

 3) int nsttLength = str.GetLength() + 1;

     pc = new char[nstrLength];

     Strncpy(pc, (LPCTSTR)str, nstrLength);

2、char* to CString

  Str.Format(“%s”, pc);

3、CString to string

  s = str.GetBuffer();

   str.ReleaseBuffer();

4、string to CString

  str.Format(“%s”, s.c_str());

5、string to char*

  pc = (char*)s.c_str();   //char*

  pc = s.c_str();         //const char*

6、char* to string

  1) string s(pc);            //初始化时

  2) s.assign(pc);          //调用成员函数
