Hello, I'm currently taking a visual basic class and having a bit of a problem with the program I'm attempting to write for this assignment. I'm currently having troubles contacting my professor, so I figured I'd ask here:

I'm essentially being asked to create an array with three columns, which isn't really the problem. The problem is that I need the ability to add things to the array, which I can't find the ability to do anywhere. I've currently tried:

- Lists/Sorted Lists -> But they can only hold two columns
- Structures -> I'm not exactly sure how to use them, so I'm probably using them incorrectly.. But from what I can tell this also doesn't work.
- An actual array -> But I can't find any information on how to write to them, so I'm assuming it's not possible.


For more specific information...

I need to gather the following information:
Family yearly income
Family ID code
# of people in family/household

and organize it into an array to print later. Any advice/tips on what to use to do this?

I'm not sure for your class... (because computer programming classes are stupid) but you'd want to create a class.. and create a list of your class... for instance...

keep in mind i don't write in visual basic... so.. this might be wrong.. but you'll get the idea..


As you see there...

then you'd just create the objects.. and add them..



OR!!! you can simly do the same thing but create a list of arrays... Create an array for each family... and a list that contains every family...

The class is the coolest because you can do advanced awesome stuff with it using LINQ like (which i've NEVER done LINQ in visual basic... but it's something like this:)



yup... LINQ is badass.

create a class that has three attributes, then use a List of that class.

or if you're a noob, you can just have 3 separate arrays/lists, one for each attribute.
