CString 转 char*

方法1.  强制类型转换

CString st1 = "method1";

LPCSTR lpbuff1= (LPSTR)(LPCSTR)st1;

....

对st1的操作会对lpbuff1产生影响

方法2.  利用strcpy

CString st2 = "method2";

char *lpbuff2 = new char[st2.GetLength()+1];

scrcpy(lpbuff2, st2);

...

delete []lpbuff2;

方法3.  利用memcpy

CString st3 = "method3";

int ilen = st3.GetLength();

char *lpbuff3 = new char[iLen+1];

ZeroMemory(lpbuff3, iLen+1);

memcpy(lpbuff3, st3, iLen);

...

delete []lpbuff3;

方法4.  利用GetBuffer

CString st4 = "method4";

char *lpbuff4 = st4.GetBuffer(st4.GetLength());

...

对st4的操作会对lpbuff4产生影响
