    Question Newbie question, C #

    Hi.

    Sorry for my bad english. But I was wondering if someome could help me out with an issue with C #. I want to make two textboxes where I can type two numbers. Then press a button and they wil be added togheter. When I make this, something happens wrong. Do I have to convert textboxes to int? How to?

    ex:
    5

    +

    5
    = 55

    I want it to be 5+5=10

    And I also have one more question. If I make a question, (with dropdownlist and a button that says "Next". When pressing this button I want a new question to appear. How to make a new "site" with a new question?

    Thanks for any answers.
    Mate

    Code:
                int res = 0;
                Int32.TryParse(this.textBox1.Text, out res);
    To be or not to be == true

    Wrong:
    "5" + "5" = "55"

    Right:
    5 + 5 = 10

    The problem you're having is you are adding two strings together, or rather you're joining two strings together.
