自动更新WinForms应用程序 [英] Auto update for WinForms application

问题描述

为.NET WinForms应用程序创建自动更新功能时，它如何更新DLL并且不影响当前正在运行的应用程序?

When creating an auto updating feature for a .NET WinForms application, how does it update the DLLs and not affect the currently running application?

由于应用程序在更新过程中正在运行，因此不会对DLL施加任何锁定(因为这些DLL必须在更新过程中被覆盖).

Since the application is running during the update process, won't there be a lock on the DLLs (because those DLLs will have to be overwritten during the update).

推荐答案

通常，您会将新文件下载到单独的区域中.然后关闭并重新启动，并在启动时查找并使用新文件(如果找到).始终保留最后一个已知的工作版本，以便用户在下载导致问题时可以恢复到一定可以正常工作的版本.

Usually you would download the new files into a separate area. Then shutdown and restart and at startup you look for and use the new files if found. Always keeping a last known working version on the side so that the user can revert to something that definitely works if the download causes problems.
