MFC 中 Int,Float,Char *,CString之间的转换

Int 转CString :
int n=1;
CString str;
str.Format("%d",n);

CString 转 Int
CString str="1";
int n=atoi(str.GetBuffer(0));

char * 转 CString:
char sz[128];
CString str;
str.Format("%s",sz);

CString 转 char *:
CString str;
int nLength=str.GetLength();
char * sz=new char[nLength];
sz=str.GetBuffer(0);
