你能發現這個DLL的任何問題嗎？

     g.Dispose(); 



    } 

    public void closeEyes(int width, int height, Graphics eyeArea) 
    { 
     int xleft = 0, yleft = 0, xright = 0, yright = 0, reye = 0, rpupil = 0; 
     xleft = width/3; 
     yleft = height/2; 
     xright = 2 * width/3; 
     yright = height/2; 
     reye = width/9; 
     rpupil = reye/2; 
     eyeArea.FillEllipse(Brushes.Gray, xleft - reye, yleft - reye, 2 * reye, 2 * reye); 
     eyeArea.FillEllipse(Brushes.Gray, xright - reye, yright - reye, 2 * reye, 2 * reye); 

    } 
} 
} 

儘管構建正確，但在引用時它不會被Visual Studio識別。 這也不是一個.NET版本的問題。我嘗試了所有4/4.5 /客戶端配置文件等。我甚至redid該項目，我連接DLL並仍然存在的問題。

是的。你的班級不公開。試着讓Class1公開，我覺得它會解決你的問題。至於爲什麼，如果你沒有明確提供一個訪問修飾符，一個類將默認爲內部。由於您在外部程序集中引用了您的類，因此Intellisense無法幫助您找到它，因爲您的外部調用程序實際上無法訪問它。
