我需要c＃中的代码

否。这里的效果不一样。



以下是询问者的预期：

1. 首先尝试你想做什么！你可能会发现它并不那么难。

2.制定你所做的事情看似问题/不工作。



尝试一下，告诉你是否面临问题。

各位会员非常乐意为此提供帮助。

i need a code in c#
No. It does not work like this here.

Here is what is expected of enquirers:
1. TRY first what you want to do! You may find that it''s not that hard.
2. Formulate what was done by you that looks like an issue/not working.

Try them and tell if you face issues.
