你可以看看这个第1步：创建Windows窗体应用程序项目 [ ^ ]特别是步骤5,6 ..有很多网上的其他开始winforms文章 - 让谷歌成为你的朋友 - 我说这不是一个痛苦，但图片胜过千言万语（试图描述'从工具栏拖动一个按钮到一个表格并挂钩它的事件'sux in words） - on你已经完成了几次，然后它是什么控制做什么的问题



提示 - 在一块上绘制/勾画'形式'纸张 - 标签，文本框（从中获取信息和（可以）向用户显示信息）和按钮 - 将标签，文本框，按钮命名为适当的 - 例如，带有+号的按钮在它上面可能是'button_add' - 主显示的文本框可能是'textbox_results' - 这意味着当你在按钮的处理程序中时，你知道计算的结果会被写入textbox_results。文本

I'm new to coding and would like to know what code I should use in order to have the operations buttons in my calculator working.

What I have tried:

Many examples on the net, they can't all be wrong I'm obviously not doing something correctly.

you could have a look at this Step 1: Create a Windows Forms Application Project[^] particularly steps 5,6.. there are plenty of other 'beginning winforms' articles on the web - let google be your friend - I say that not to be a pain, but pictures are worth a thousand words (trying to describe 'dragging a button from the toolbar onto a form and hooking up its event' sux in words) - once you've done it a few times, then its a matter of what control(s) do what

hint - draw/sketch the 'form' on a piece of paper - 'labels', textboxes (where you get information from and (can) display information back to your user), and buttons - name the labels, textboxes, buttons something appropriate - for example, a button with a '+' sign on it might be 'button_add' - a textbox for your main display may be 'textbox_results' - that means when you're in the 'handler' for your button(s), you know the result of the calculation gets written to textbox_results.Text
