테두리가없는 창 주위의 그림자에 대해이 코드를 보았습니다. 그러나 여기에서는 내 문제입니다. using System.Windows.Interop;은 밑줄이 그어져 있으며 참조 할 수 없습니다. 나는 그것의 상호 운용성에 연결 추측 있도록 또한 public static void DropShadowToWindow(Window window)이 창은'using System.Windows.Interop;' 어디 있니?

이것은 WPF 코드이므로 올바른 프로젝트 템플릿을 시작해야합니다. 그런 다음 System.Drawing에 대한 참조를 추가합니다. 이상하게 섞어서, 당신이 이해하지 못하는 코드를 복사/붙여 넣기하지 않는 것이 가장 좋습니다. –
