asp.net 删除目录session丢失解决方案

1.首先添加一个类StopAppDomainRestartOnFolderDelete.cs

代码如下：

 1 using System;
 2 using System.Collections.Generic;
 3 using System.Linq;
 4 using System.Web;
 5 using System.Reflection;
 6 namespace MyWebsite
 7 {
 8     public class StopAppDomainRestartOnFolderDeleteModule : IHttpModule
 9     {
10         public void Init(HttpApplication context)
11         {
12             PropertyInfo p = typeof(HttpRuntime).GetProperty("FileChangesMonitor", BindingFlags.NonPublic | BindingFlags.Public | BindingFlags.Static);
13             object o = p.GetValue(null, null);
14             FieldInfo f = o.GetType().GetField("_dirMonSubdirs", BindingFlags.Instance | BindingFlags.NonPublic | BindingFlags.IgnoreCase);
15             object monitor = f.GetValue(o);
16             MethodInfo m = monitor.GetType().GetMethod("StopMonitoring", BindingFlags.Instance | BindingFlags.NonPublic);
17             m.Invoke(monitor, new object[] { });
18     
19         }
20         public void Dispose() { }
21     }
22 }

2.修改web.config文件

在<httpModules>节点中添加 <add name="stopAppDomainRestartOnFolderDelete" type="MyWebsite.StopAppDomainRestartOnFolderDeleteModule" />

。stopAppDomainRestartOnFolderDelete 自定义名称建议与类名相同

。MyWebsite.StopAppDomainRestartOnFolderDeleteModule StopAppDomainRestartOnFolderDelete.cs 命名空间.类名称
