在C#中使用OpenCvSharp4出现无法加载 DLLOpenCvSharpExtern:找不到指定的模块。
或者提示“OpenCvSharp.NativeMethods”的类型初始值设定项引发异常
如以下图片的提示：
解决方法：
把缺少的OpenCvSharpExtern.dll放到Debug目录下，若没有OpenCvSharpExtern.dll可自行下载即可，提供NuGet下载方法：
再次运行程序，即可解决问题：
				
the type initializer for '' threw an exception
问题：程序启动时初始化主窗口类时，弹出该错误。调查：查看类的构造函数是否会有异常抛出。解决：去掉类的构造函数中可能出现的异常。
