动态封杀与解封IP

不论IIS6还是IIS7 都可以把需要封杀的IP加入封杀列表。但是需要注意的是我们代码写的是全部替换原先的数据。但是在IIS7下，执行的效果是原先的不替换，新加一批封杀 IP。当然IIS7下，如果新加的IP原来就有了，则会报如下异常：

System.Runtime.InteropServices.COMException was caught 
  Message="当文件已存在时，无法创建该文件。 (异常来自 HRESULT:0x800700B7)" 
  Source="System.DirectoryServices" 
  ErrorCode=-2147024713 
  StackTrace: 
       在 System.DirectoryServices.DirectoryEntry.CommitChanges() 
       在 IIS_Security_ConsoleApplication.Program.IPDeny() 位置 D:MyCodesIIS_Security_ConsoleApplication IIS_Security_ConsoleApplicationProgram.cs:行号 109 
  InnerException:

这就是说，IIS7， 我们可以通过编程接口增加封杀IP名单，但是没发通过编程接口剔出封杀IP。

如果谁知道怎么在iis7下面提出限制ip的请M我 571111539@qq.com，下面代码不是很完整，自行修改
