从ASP.NET应用程序中删除Bin DLL文件？

Question

How can I remove Bin DLL Files from within a ASP.NET App?

When I try it on IIS 7.5, it says "Permission denied".

I wrote a codebehind script, to remove DLL files from within the bin directory. The code snippet is as below:

string[] filesList = Directory.GetFiles(System.Web.HttpRuntime.BinDirectory, "*.dll");
foreach (string f in filesList)
{
    try
    {
        File.Delete(f);
        app.Context.Response.Write("R: " + f + "\n");
    }
    catch (IOException deleteError)
    {
        app.Context.Response.Write(deleteError.Message);
    }
}

It works fine on the VisualStudio IIS Express, but doesn't work on a production IIS 7.5 server.

Answer 1

您将需要以管理员身份运行IIS，然后重置IIS并暂时停止asp.net应用程序，然后可以打开Bin文件夹并删除DLL。

Answer 2

By default, IIS watches the bin folder automatically, any change to it will cause an immediate Application-Pool recycle.

You can change this setting in IIS manager though:

Application Pools > [Your_App_Pool] > Advance Settings > Disable Recycling for Configuration Changes = True .
