Question Iterate through structure fields

[spdracer22]

I have a structure that keeps track of several different structures that contain fields, and I want to know if it's possible to iterate through these to perform math operations.

My structures go something like this:

Structure subStruct
    val 1 as double
    val 2 as double
    val 3 as double
End Structure

Structure mainStruct
    sub1 as subStruct
    sub2 as subStruct
    sub3 as subStruct
End Structure

What I want to do is something like can be done with collections:

Dim myStruct as mainStruct

For each a as subStruct in myStruct

    a.val1 += 1

Next

However, because it's not a collection, it won't work right. The idea behind wanting to do things this way, is that I don't have to change my underlying math code if I want to add or remove sub structures from my main structure.

If anyone has any ideas, let me know. It's also early enough in the design/coding phase that I can make some wholesale changes if things would work better another way.

Hello.

You can use Reflection to achieve that. Something like:

For Each field As System.Reflection.FieldInfo In yourStruct.GetType().GetFields
 
Next
