推荐答案

^ ]是与此有关的代码项目文章.

Here[^] is a Code Project article on this.

警告！

不幸的是，Cristian所引用的文章是完全错误的.它具有一个基本缺陷-由于无法卸载已加载的程序集而导致的内存泄漏.我在文章中添加了评论，警告所有人不要使用它.

另外，其中一位成员坚持认为，这篇文章窃了他的工作.请查看对文章的评论:一位评论者提供了更好的文章: http://www .west-wind.com//presentations/dynamicCode/DynamicCode.htm [使用CodeDom生成代码 [创建使用可重载插件的WPF应用程序... [ ^ ].

Warning!

Unfortunately, the article Cristian referenced is all wrong. It has a fundamental flaw — a memory leak due to the fact that it is impossible to unload a loaded assembly. I added my comment to the article warning everyone against using it.

Also, one of the members insists that this article plagiarizes his work. Please look at the comment to the article: one of the commenter offered much better article: http://www.west-wind.com//presentations/dynamicCode/DynamicCode.htm[^].

Also, I explain the problem of unloading and describe the solution using System.AppDomain which is probably the only correct approach. Please see:
