    Question Newbie question, C #


    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?



    = 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.

                Int32.TryParse(this.textBox1.Text, out res);

    "5" + "5" = "55"

    5 + 5 = 10

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