I am creating winform to process (convert txt files to tiff) large amount of files. I put all the code behind a button (btnProcess). Is this a good idea? It works but I noticed when I go away from the winform and come back to this I see blank window until the process is complete. I heard about background worker. what is the purpose of background worker?

推荐答案

这里你需要的是多线程.这意味着两个(或更多)代码线程将并行运行.其中之一是 UI 线程，负责绘制窗口的线程.在您的情况下，您在 UI 线程中运行代码，因此在代码运行时阻止了 UI 呈现.

What you need here is multi-threading. That means that two (or more) threads of code would run in parallel. One of them would be the UI thread, the one responsible for drawing the window. In your case you are running your code in the UI thread and thus blocking the UI rendering while your code is running.

BackgroundWorker 的目的是启动对新线程的操作，这正是您所需要的.

The purpose of the BackgroundWorker is to start an operation on a new thread and is what you need.
