我正在尝试以编程方式使外部WinForms应用程序将其数据复制到剪贴板，这让我发疯。
由于在应用程序中按Ctrl-C做了正确的事情，我一直在尝试使用我的C＃应用程序将ctrl-c发送到另一个应用程序。
这是我的命令序列。我使用Spy ++比较了这些消息，除了我的SendMessages显示为发送和接收之外，它匹配，而WinForm上显示的相同操作显示为已发布。
我的代码：
NativeMethods.SendMessage(hwnd, WM_KEYDOWN, 0x00000011, 0x001D0001);
NativeMethods.SendMessage(hwnd, WM_KEYDOWN, 0x00000043, 0x002E0001);
NativeMethods.SendMessage(hwnd, WM_CHAR, 0x00000003, 0x002E0001);
NativeMethods.SendMessage(hwnd, WM_KEYUP, 0x00000043, 0xC02E0001);
NativeMethods.SendMessage(hwnd, WM_KEYUP, 0x00000011, 0xC01D0001);
