c# OpenCvSharp 无法加载 DLLOpenCvSharpExtern:找不到指定的模块

在C#中使用OpenCvSharp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：

 

 

 

 而你的程序bin文件夹却有dll文件夹

 

 

 

 

 

 还是无法正确的读取OpenCvSharpExtern

可在使用OpenCvSharp前调用如下代码

让库OpenCvSharpExtern.dll是从应用程序路径的x86或x64子目录动态加载

[DllImport("kernel32", SetLastError = true, CharSet = CharSet.Ansi)]
        private static extern IntPtr LoadLibrary([MarshalAs(UnmanagedType.LPStr)] string lpFileName);

        #region 检查指针大小，让库OpenCvSharpExtern.dll是从应用程序路径的x86或x64子目录动态加载
        public static bool TryLoadNativeLibrary(string path)
        {
            if (path == null)
                return false;

            path = Path.Combine(path, IntPtr.Size == 4 ? "x86" : "x64");

            path = Path.Combine(path, "OpenCvSharpExtern.dll");

            return File.Exists(path) && LoadLibrary(path) != IntPtr.Zero;
        }
        #endregion
