推荐答案

您不需要在.NET中释放或释放内存，除非您在讨论非托管内存，这取决于非托管API。

这是由垃圾收集器。请参阅： http://en.wikipedia.org/wiki/Garbage_collection_%28computer_science%29 [< a href =http://en.wikipedia.org/wiki/Garbage_collection_%28computer_science%29target =_ blanktitle =New Window> ^ ]。



我希望你明白：如果没有足够的内存，那还不够。但是，您可以按照一次使用较少的方式设计应用程序。首先，您需要消除内存泄漏。有人认为，如果你不释放内存，托管代码中就不可能发生内存泄漏。这不是真的。当一些对象变得无法访问时，内存被回收（参见上面引用的文章）。您的代码可以收集越来越多的可访问但不可用的对象，因此它们不会被检测为未使用和销毁。

You don't need to free or release memory in .NET, unless you are talking about unmanaged memory, which is up to unmanaged APIs.
This is done by the Garbage Collector. Please see: http://en.wikipedia.org/wiki/Garbage_collection_%28computer_science%29[^].

I hope you understand: if there is no enough memory, it's not enough. However, you can design your application the way it uses less at a time. First of all, you need to eliminate memory leaks. Some think that, if you don't free memory, memory leaks are impossible in the managed code. This is not true. Memory is reclaimed as some objects become unreachable (see the article referenced above). Your code can collect more and more reachable but not usable objects, so they cannot be detected as unused and destroyed.
