Char*转为Wchar_t*的问题

[a5796489]

我用MultiByteToWideChar怎么转都是乱码，但用CString来进行过度一下就行了靠，这是怎么回事？原理是什么？求教育

看看CString类的构造函数

CString(LPCSTR lpsz);
	// from a UNICODE string (converts to TCHAR)
	CString(LPCWSTR lpsz);
	// subset of characters from an ANSI string (converts to TCHAR)
	CString(LPCSTR lpch, int nLength);
	// subset of characters from a UNICODE string (converts to TCHAR)
	CString(LPCWSTR lpch, int nLength);
	// from unsigned characters
	CString(const unsigned char* psz);
