I have multiple text boxes (tbVarName1, tbVarName2, ... tbVarName[n]) and I want to increment them in a for loop to assign the text to something

Question

I have a multiple text boxes that I want to assign their string content to a variable however I'm not sure how to increment the text boxes. They are named, tbVarName1, tbVarname2, et cetera. Below is the for loop I have, right now I just have tbVarName1 hard coded in.

I have researched some of what other people have done and have only found tips for doing it in VB.

        for(seriesIndex = 1; seriesIndex <= 4; seriesIndex++)
        {
                dataChart.Series["Variable " + seriesIndex].LegendText = tbVarName1.Text 
        }

At the end of this I would like the the legends to be updated to what's in the text boxes

There are various ways to do this, one way is to add the controls into an array, for example:

var controls = new [] { tbVarName1, tbVarName2, tbVarName3 };

And now you can access them by index:

for(seriesIndex = 1; seriesIndex <= 4; seriesIndex++)
{
    dataChart.Series["Variable " + seriesIndex].LegendText = controls[seriesIndex - 1].Text;
    //                                                       ^^^^^^^^^^^^^^^^^^^^^^^^^
    //                                                       Like this
    //                                                       Note: arrays start at zero
