Type initialization exception

Question

I created imageHolder class:

public class ImageHolder : Image<Bgr, Byte>
{   
    private String imagePath;

    public ImageHolder(String path):base(path)
    {
       this.imagePath = path;                     
    }   
    public String imgPathProperty
    {
        get
        { return imagePath; }
        set
        { imagePath = value; }
    }
}

I create instance of the class and initialize it,like this:

private ImageHolder originalImageHolder;
originalImageHolder = new ImageHolder(openFileDialog.FileName);

In runtime i get this exception:

The type initializer for 'Emgu.CV.CvInvoke' threw an exception.

enter image description here

Here is Solution Explorer window:

Any idea why i get this exception and how can i fix it?

Thank you in advance.

Looks like it can't find opencv_core240.dll; does that need to be in the same folder? — zimdanen, Sep 14 '12 at 13:08
not exactly a duplicate of this (since there was no accepted answer)but maybe some of the information on [this other question](http://stackoverflow.com/questions/10930610/opencv-unmanaged-dlls-not-found-asp-net) and answers may work for you — Paolo Falabella, Sep 14 '12 at 13:11
To reiterate and expand on what @zimdanen said, the InnerException text states that it was unable to load the DLL zimdanen mentions. See http://stackoverflow.com/questions/2066180/the-specified-module-could-not-be-found-0x8007007e for an explanation. — akton, Sep 14 '12 at 13:15

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 InnerException property is the property that contains the detail of the exception that was actualy thrown - this is the exception that you need to investigate.

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

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)

I'd suggest that you take a look at this question to see if any of the suggestions on there help you.

VS Project Properties Page

Checking this field did the trick for me. Under Project→ Properties→ Build (Main/Startup project)

Yes - this fixed the issue for me too. Turns out the DLL my project requires can only be run in 32 bit! D'oh! – Mark Oct 09 '18 at 15:13

I solved the problem by reinstalling MSVCRT 9.0 SP1 x86
