并调用的Response.Redirect（）using块调用Dispose（）内部？ [英] Does calling Response.Redirect() inside of a using block call Dispose()?

问题描述

可能重复：结果
的的Response.Redirect（“”的）内部及ldquo;使用{}”的

差不多了。如果我有，例如，在使用说明和地方，using语句内部数据库的连接我重定向到另一个网页，它会处理我的连接，或者我必须先手动调用它呢？

Pretty much that. If I had, for example, a connection to the database in a using statement and somewhere inside that using statement I redirected to another page, would it dispose of my connection or would I have to manually call it first?

推荐答案

是的，这绝对会叫的Dispose 。一个使用声明的一点是，的Dispose 被称为在最后块，这样的资源将被配置在块是否正常或异常结束。

Yes, it would absolutely call Dispose. The point of a using statement is that Dispose is called in a finally block, so the resource will be disposed whether the block completes normally or with an exception.

有这里有一个的轻微的皱纹在IIRC，的Response.Redirect 抛出一个 ThreadAbortException 如果它抓住了，它会自动重新抛出，但是这不应该影响一个最后块。

There's a slight wrinkle here in that IIRC, Response.Redirect throws a ThreadAbortException which will automatically rethrow if it's caught, but that shouldn't affect a finally block.
