如何創建處理

Question

添加下一個變化：

Emily::oSeMac^ Terminal; 
    Emily::AsyncSocketController^ _socketManager; 
    delegate void DataArrival(String^, array<unsigned char, 1>^, System::Net::IPEndPoint^); 

    void _socketManager_onDataArrival(String^ SocketID, array<unsigned char, 1>^ SocketData, System::Net::IPEndPoint^ RemoteIP) 
    { 
     System::Object^ retData = Terminal->WhoCame (SocketID, SocketData, RemoteIP, _socketManager, 0); 
    } 
    Form1(void) 
    { 
     InitializeComponent(); 
     _socketManager = gcnew Emily::AsyncSocketController(2000); 
     _socketManager->onDataArrival += gcnew DataArrival(this, &AC_WebPassManager::Form1::_socketManager_onDataArrival); 
     _socketManager->Start(); 
     Terminal = gcnew Emily::oSeMac(); 
    } 

錯誤錯誤C2664： '艾米莉:: AsyncSocketController :: onDataArrival ::添加'：不能轉換參數1 'AC_WebPassManager :: Form1中::^DataArrival事件'到'Emily :: AsyncSocketController :: onDataArrivalEventHandler ^' 1>沒有用戶定義的轉換運算符可用，或者 1>指向的類型是不相關的;轉換要求reinterpret_cast，C樣式轉換或函數樣式轉換 1>

Answer 1

 
_socketManager->onDataArrival += gcnew DataArrival(this, 
    &Test::Form1::_socketManager_onDataArrival_); 

DataArrival事件是委託：

 
public delegate DataArrival(String^, array<unsigned char, 1>^, System::Net::IPEndPoint^); 

可能它已被定義的地方，用其他的名字 - 看看這個委託定義Emily命名空間。
