Visual Studio 2008：C#修改内容未在ASP内网站点/应用中显示

Hey there! Since you're primarily working with VBA and SQL and only have a basic grasp of C#, let's break down the most common fixes for this issue—no deep .NET expertise required.

Common Causes & Fixes #

• Restart the IIS Application Pool or Site
  IIS often caches compiled ASP.NET content or keeps files locked, preventing your changes from showing up. Here's how to refresh it:

  1. Open IIS Manager, locate your target site.
  2. First, double-check you edited the right files: click Basic Settings on the right-hand pane to confirm the site's physical path matches where you saved your changes.
  3. Right-click your site's associated Application Pool (found under the "Application Pools" node) and select Recycle.
  4. Alternatively, right-click the site itself, choose Stop, then Start to fully restart it.

• Clear Browser Cache
  Browsers love caching static content (like HTML, CSS, or JS files) to speed up loads. Force a full refresh to bypass cached content:

  • Press Ctrl + F5 (Windows) or Cmd + Shift + R (Mac) directly on the site.
  • Test the site in incognito/private mode—this loads content without using stored browser cache.

• Delete ASP.NET Temporary Compilation Files
  ASP.NET compiles aspx/ascx files into DLLs stored in a temporary folder. Old compiled files might override your updated text:

  1. Navigate to the temporary files directory (path varies by .NET version; for .NET Framework 4.x it's usually):

     C:\Windows\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files
     

  2. Find the folder linked to your site, delete all its contents.
  3. Recycle the application pool again after deleting these files.

• Check File Permissions
  Sometimes IIS can't access your modified files if permissions are misconfigured. Ensure the IIS application pool identity (usually IIS AppPool\[YourPoolName]) has read access to the files you edited.

• Rule Out CDN/Reverse Proxy Caching
  If your site uses a CDN or internal reverse proxy, it might be serving cached old content. You'll need to purge the CDN cache or reach out to your admin team to refresh the proxy cache if this applies.
