標題[問題] C# 引用 C++ dll的問題
時間Mon May 21 19:01:45 2012
我目前開發的程式語言是C#，最近拿到一個API的文件,需引用HsFutuSDK.dll裡的
function
已我所知的，我目前只能使用DllImport三個function
1. IFuMessage* HSAPI NewFuMessage(int iMsgType = MSG_TYPE_UNKNOWN,int
iMsgMode = MSG_MODE_UNKNOWN);
2. IHsFutuComm* HSAPI NewFuCommObj(void* lpReserved = NULL);
3. int HSAPI GetSDKVersion();(已能呼叫成功)
我的問題，大概都在於如何改成讓C#可使用他struct裡的功能，如：
1. 是要如何去引用在 IHsFutuComm 裡的function 如 SetConfig、Start等。
2. 像virtual unsigned long HSAPI QueryInterface( const char * iid, IHSKnown
**ppv ) = 0; 這種的重新宣告成C# 要如何改
是否有人能解我疑惑?感激!!!!
C++使用的範例內容的程式標頭檔，例了一些，如下：

#else
# define HSAPI
#endif
