问题描述
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);
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);
That's when I get this error.
The process cannot access the file 'c:codeContentCMSLandingPagesTest2' because it is being used by another process.
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?
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.
