在 WP7 上释放 Application.GetResourceStream 返回的底层流 [英] Releasing underlying Stream returned by Application.GetResourceStream on WP7

问题描述

当使用 Application.GetResourceStream 访问资源时，它返回一个 StreamResourceInfo 类的实例，这个类没有实现 IDisposable.

When accessing a resource using Application.GetResourceStream it returns an instance of the class StreamResourceInfo, this class does not implement IDisposable.

当我在 WP7 设备上完成处理流时，我是否应该关闭\处置由 StreamResourceInfo 公开的底层流 - 我不想知道 Using或处置模式.

Should I close\dispose the underlying stream exposed by StreamResourceInfo when I've finished processing the stream on a WP7 device - I don't want to know about Using or the Dispose pattern.

一个例子是使用该方法访问包含在 ZAP 包中的 ZIP 文件，一旦我解压了该文件，我就不再需要 Stream 实例.

An example would be using the method to access a ZIP file which is contained with the ZAP package and once I have unzipped the file I don't need the Stream instance anymore.

推荐答案

提供的代码示例 这里 没有使用 using、Close() 或 Dispose().

The code example provided here does not make use of using, Close() or Dispose().

因为 StreamResourceInfo 的文档没有提到 Close() 或 Dispose()(和 StreamResourceInfo实际上并不从 Stream 或任何其他可能实现这些方法的东西继承)，我认为让对象超出范围并自然地进行垃圾收集是安全的.

Since the documentation for StreamResourceInfo doesn't mention Close() or Dispose() (and StreamResourceInfo does not actually inherit from Stream or anything else that might implement these methods), I think it's safe to just let the object go out of scope and garbage collect naturally.

我怀疑 StreamResourceInfo 类有一个终结器，它在垃圾回收期间在底层 Stream 对象上调用 Dispose()，但我没有我目前没有可用的 Reflector 副本来验证这一点.IDisposable 模式在这方面非常强大.

I suspect that the StreamResourceInfo class has a finalizer that calls Dispose() on the underlying Stream object during garbage collection, but I don't have a copy of Reflector available to me at the moment to verify that. The IDisposable pattern is quite robust in that regard.

但是，如果您仍然对这种不确定性感到不舒服，您可以随时在 Stream 对象上调用 Close().

However, if you still feel uncomfortable with that level of uncertainty, you can always call Close() on the Stream object.
