因为它正由另一个进程过程不能访问该文件 [英] process cannot access the file because it is being used by another process

问题描述

我使用ASP.NET Web表单使用C＃。在一个页面上我点击提交来创建服务器上的文件。

I am using ASP.NET Webforms with C#. On one page I click submit to create a file on the server.

File.Create(Server.MapPath(ConfigurationManager.AppSettings["LandingPages"]) + landingPage.FriendlyName);

这工作正常，并创建文件的预期。但是，它这样做后，重定向到另一个网页，其内容为刚创建的文件。

This works fine and creates the file as expected. However, after it does this it redirects to another page, which reads the file that was just created.

var landingPageContent = File.ReadAllText(Server.MapPath(ConfigurationManager.AppSettings["LandingPages"]) + landingPage.FriendlyName);

当我得到这个错误的。

该进程无法访问该文件。C：\ code \内容\ CMS \ LandingPages \ Test2的'，因为它正由另一个进程使用

The process cannot access the file 'c:\code\Content\CMS\LandingPages\Test2' because it is being used by another process.

如果我重新启动IIS那么这个过程释放的文件，我可以加载页面并阅读文件就好了。有什么我需要做的后 File.Create 以重定向之前关闭文件？

If I restart IIS then the process releases the file and I can load that page and read the file just fine. Is there something I need to do after File.Create in order to close the file before the redirect?

推荐答案

你附近 File.Create 返回的流？这个名字是有点混乱（说到一路从WinAPI的的肠子），但它会创建一个文件的和的打开它写你。

Did you close the stream returned by File.Create? The name is a bit confusing (it comes all the way from the bowels of WinAPI), but it creates a file and opens it for writing for you.
