I am trying to mentally translate this line Dim loObject(4) As Object

into C# code and I can not. May be because of my not knowing C# well enough.

What this line does in VB.NET?


In C# code I would probably create myImage class instead and use it to add to collection and access properties.


>>It is a strange code. What is loObject(1)? Shouldn't you use loObject.Name instead and other properties?
>>
>>Also, in C# you will need to give a type to the loObject in this code. I don't see a type in your code.

>This approach allows to create a collection in two-dimensional array. Thus, each entry in the collection contains several items. I have this all over the framework for years. This has proven to work exceptionnally well so far. So, basically, as the entry in a collection can have multiple types, I have object. So, when the collection is built, it builds up an object and store it in the collection. So, I can scan the collection for the name that I am looking for. Then, I can extract any property I want from it.
