Question

I am trying to take the values in the textboxes, named sequentially from 0-9, and add that to a List using a for loop. I am having problems with the syntax or something.

here is what I have now.

for (int i = 0; i <= amt.Count(); i++)
        {
            amt[i] = int.Parse(amtBox[i].Text);
        }

The error is that amtBox doesnt exist in the current context.

My problem is within the loop where i have amtBox[i].Text. I have tried this several ways and VS always throws an error. I have tried “amtBox” + i and that compiles but then causes an error when I try to do something with it and says “data is of wrong type”.

I am new to C# and come from PHP so maybe that is why I think this approach will work. PHP doesnt care about data types where C# really does. I have done this exact thing in PHP many times without any issue.

Any suggestions on another way to do this are appreciated as I am probably coming at this all wrong.

Thanks

One solution would be to declare an array and assign amtBox’es to the individual indexes in the array and then you can iterate on that array.

var amtBoxes = new TextBox[] { amtBox0, amtBox1, .... };
for (int i = 0; i <= amt.Count(); i++)
{
    amt[i] = int.Parse(amtBoxes[i].Text);
}

If you end up needing to iterate on your TextBox controls in other places I would consider making the array an instance member of your object.
