Why this code is run only the first part?

            }
        case 2: //no run?
            {
                s += i;
                MessageBox .Show ("2");
                webBrowser1.Navigate("www.bing.com");
                break;
            }
    }
}

推荐答案

也许您是否使用了正确的文本框?

Perhaps if you used the right textbox?

int s = Int32.Parse(textBox3.Text); //textbox1=1

请注意此处的数字...

这就是我永远对初学者说的原因:切勿对对象名称使用VS默认值.这会引起混乱-使用描述用户将如何处理事情的名称！ tbSelectSearchEngine很难混淆...

Note the numbers there...

This is why I am forever saying to beginners: Never use the VS defaults for object names. It leads to confusion - use names which describe what the user will do with things! tbSelectSearchEngine is a lot harder to confuse...
