1. You should add C# to Relevant Tags, otherwise your question scope is too broad.
2. Generally this community likes to see one's will to try, that is, you try to make it first, ask later when you are having difficulties. It doesn't matter it doesn't work, or work incorrectly, just share your attempted code link in Description input of your original post above.

* I will remove this note when you updated the post to include code link.
Best of luck! 👍
