任何人都可以告诉我为什么我不能从它的项目外部访问此代码？

I found some code online for image searching/recognition and since I do not know barely any csharp I put it in a class and built it. Now when I try to access it from a vb project it does not show up. Even after it is referenced I cannot actually access it. I am geussing because the functions are not shared, and as I understand "Static" in C# is the same as "Shared in vb.net. Although when adding it in I get errors. Can anyone confirm if this is the issue why I can't access it?? Same goes for when I referenced this proejct from my vb.net project I could not access the classes either.I found some code online for image searching/re
