我正在用 C# 中的 Emgu.CV 编写一个程序
我在编译时收到这个错误
An unhandled exception of type 'System.IO.FileNotFoundException' occurred in InAirSignature.exe
Additional information: Could not load file or assembly 'Emgu.CV.UI, Version=2.9.0.1922, Culture=neutral, PublicKeyToken=7281126722ab4438' or one of its dependencies. The system cannot find the file specified.
任何想法如何解决？ 对于我的编码，需要一个网络摄像头。 下面是我的代码。
