MFC:在Unicode编码下CString、char *转换

一、CString转char *

CString pb=_T("abc");
int len = WideCharToMultiByte(CP_UTF8, 0, pb, pb.GetLength(), NULL, 0, NULL, NULL);
    char* pa = new char[len + 1];
    len = WideCharToMultiByte(CP_UTF8, 0, pb, pb.GetLength(), pa, len + 1, NULL, NULL);
    pa[len] = 0;
//pa就是最后转换成的char *

二、char * 转CString

CString st=_T("123");
 int nLength = st.GetLength();
 int nBytes = WideCharToMultiByte(CP_ACP,0,st,nLength,NULL,0,NULL,NULL);
 char* path1 = new char[ nBytes + 1];
 memset(path1,0,nLength + 1);
 WideCharToMultiByte(CP_OEMCP, 0, st, nLength, path1, nBytes, NULL, NULL);
 path1[nBytes] = 0;
