Answer 1

You need to connect to the process, it involves a lot of Windows API and it is different for different applications. My advise, don't do it, I cannot imagine an architecture which includes this kind of actions, it is asking for bugs.

But, if you still want to do it, Google: "connect to a process notepad and change text c#"

You will find many links which explain. For example this one: https://www.codeproject.com/Articles/670373/Csharp-Read-Write-Another-Process-Memory

Answer 2

写入另一个记忆的过程更复杂，更不稳定。更好的想法是将消息/事件发送到另一个进程。 This链接演示了记事本，但其他编辑的想法相似。
