Multiple Variables

Question

Is there a way to give a value to multiple variables (integers in this case), instead of all at once?

For instance, I have Dim aceVal, twoVal, threeVal, fourVal, fiveVal, sixVal, sevenVal, eightVal, nineVal, tenVal As Integer and, pending listbox selection, I'd like to assign threeVal fourVal and sixVal all values of -1.

How can I do this? Thanks.

Answer 1

I really don't mean to be a jerk, but is there any reason why you can't just do:

threeVal = -1
fourVal = -1
sixVal = -1

Answer 2

There is no way in vb.net to assign them all on one line like threeVal=fourVal=SixVal.

If you need all these variables then one line at a time is the way. I would suggest if -1 is going to be used a lot then create a constant for it and assign the var's to the constant.

I would also consider using an array or collection to store all your values if possible and work with them in order for setting / retrieving their values. You then won't have to have 60 variables littered all in your code. Array and/or collection would be a little cleaner.

Answer 3

You could use an array/dictionary like so:

Dictionary myValues = new Dictionary();

myValues.Add("FirstVal", 1);
myValues.Add("SecondVal", -1);
myValues.Add("ThirdVal", 1);

You could then write a simple function:

public updateMyValues(string[] myKeys, int myValue)
{
     foreach (string s in myKeys)
        {
            myValues[s] = myValue;
        }
}

And finally when your list box changes you could just call the function to update the variables you want like so:

upDateMyValues({"FirstVal", "ThirdVal"}, -1);

Hope this helps.
