推荐答案
你的意思是？ ：
textbox3.text = textbox1.text + textbox2.text
但要小心，textbox包含字符串，输入必须包含
数字不得异常。
You mean? :
textbox3.text = textbox1.text + textbox2.text
But be careful textbox holds strings, that your input must consist of
numbers not to get an exception.

实际上，这会连接字符串。如果Textbox1.text =" 4"和
textbox2.text =" 5"然后textbox3.text将被设置为45。如果Textbox1.text
=" Blue"和textbox2.text =" green"，然后textbox3.text将设置为
" Bluegreen"。
Actually, this concatenates the strings. If Textbox1.text = "4" and
textbox2.text = "5" then textbox3.text will be set to "45". If Textbox1.text
= "Blue" and textbox2.text = "green", then textbox3.text will be set to
"Bluegreen".
