ASP.NET清空缓存时遇到的问题简析

上面方法由于是通过crack的方法进行调用，可能有潜在的问题，因此仅供参考。

在google上搜索到另外一篇文章，主干是代码，代码的思路和我一样，贴过来也供参考。

private void clearOutputCache() 
{ 
 Type ct = this.Cache.GetType(); 
 FieldInfo cif = ct.GetField( "_cacheInternal", BindingFlags.NonPublic | BindingFlags.Instance ); 
 Type cmt = Cache.GetType().Assembly.GetType( "System.Web.Caching.CacheMultiple" ); 
 Type cachekeyType = Cache.GetType().Assembly.GetType( "System.Web.Caching.CacheKey" ); 
 FieldInfo cachesfield = cmt.GetField( "_caches", BindingFlags.NonPublic | BindingFlags.Instance ); 
 
 object cacheInternal = cif.GetValue( this.Cache ); 
 object caches = cachesfield.GetValue( cacheInternal ); 
 
 Type arrayType = typeof( Array ); 
 MethodInfo arrayGetter = arrayType.GetMethod( "GetValue", new Type[] { typeof( int ) } ); 
 object cacheSingle = arrayGetter.Invoke( caches, new object[] { 1 } ); 
 
 FieldInfo entriesField = cacheSingle.GetType().GetField( "_entries", BindingFlags.Instance | BindingFlags.NonPublic ); 
 Hashtable entries = (Hashtable) entriesField.GetValue( cacheSingle ); 
 
 List<object> keys = new List<object>(); 
 foreach( object o in entries.Keys ) 
 { 
  keys.Add( o ); 
 } 
 
 MethodInfo remove = cacheInternal.GetType().GetMethod( "Remove", BindingFlags.NonPublic | BindingFlags.Instance, null, 
  new Type[] { cachekeyType, typeof( CacheItemRemovedReason ) }, null ); 
 foreach( object key in keys ) 
 { 
  remove.Invoke( cacheInternal, new object[] { key, CacheItemRemovedReason.Removed } ); 
 } 
}
