public ImageHolder(String path):base(path)
{
this.imagePath = path;

set

The TypeInitializationException (the exception that you are seeing) is thrown whenever a static constructor throws an exception, or whenever you attempt to access a class where the static constructor threw an exception - its InnerExceptionproperty is the property that contains the detail of the exception that was actualy thrown - this is the exception that you need to investigate.
该TypeInitializationException（不同的是，你所看到的）被抛出时静态构造函数抛出一个异常，或当您试图访问一个类，其中静态构造函数抛出异常-它的InnerException属性是一个包含了异常的细节财产实际上被抛出 - 这是您需要调查的异常。
In this case from your screenshot the problem appears to be that the DLL "opencv_core240.dll" could not be found. This could be for a number of reasons
在这种情况下，从您的屏幕截图来看，问题似乎是找不到 DLL“opencv_core240.dll”。这可能有多种原因
- The DLL couldn't be found
- One of the dependencies of the DLL could not be found
- The DLL was in the incorrect image format (32 bit as opposed to 64 bit)
- 找不到 DLL
- 找不到 DLL 的依赖项之一
- DLL 的图像格式不正确（32 位而不是 64 位）
I'd suggest that you take a look at this questionto see if any of the suggestions on there help you.
我建议你看看这个问题，看看那里的任何建议是否对你有帮助。
