asp.net 删除项目文件/文件夹IIS重启，Session丢失问题

/// <summary> 
/// Stops the ASP.NET AppDomain being restarted (which clears 
/// Session state, Cache etc.) whenever a folder is deleted. 
/// </summary> 
public class StopAppDomainRestartOnFolderDeleteModule : IHttpModule 
{ 
private static bool DisableFCNs = false; 
public void Init(HttpApplication context) 
{ 
if (DisableFCNs) return; 
PropertyInfo p = typeof(HttpRuntime).GetProperty("FileChangesMonitor", BindingFlags.NonPublic | BindingFlags.Public | BindingFlags.Static); 
object o = p.GetValue(null, null); 
FieldInfo f = o.GetType().GetField("_dirMonSubdirs", BindingFlags.Instance | BindingFlags.NonPublic | BindingFlags.IgnoreCase); 
object monitor = f.GetValue(o); 
MethodInfo m = monitor.GetType().GetMethod("StopMonitoring", BindingFlags.Instance | BindingFlags.NonPublic); 
m.Invoke(monitor, new object[] { }); 
DisableFCNs = true; 
} 
public void Dispose() { } 
} 
 
随后在Web.Config中加入Module配置 
 代码如下:

<!--解决删除项目文件/文件夹引起的IIS重启--> 
<add name="stopAppDomainRestartOnFolderDelete" type="DeployAssistant.Facade.Web.StopAppDomainRestartOnFolderDeleteModule,DeployAssistant.Facade"/> 
 
这样每次再删除文件/文件夹AppDomain都不会重启了，Session也不会丢失了。世界也变得更美好了！ 

PS：Web.Config和bin文件夹下的改动依然会让Web重启，这也是必须保留的！
