string str = " ";
IDictionaryEnumerator CacheEnum = HttpRuntime.Cache.GetEnumerator();

while (CacheEnum.MoveNext())
{
str += "缓存名 <b> [ " + CacheEnum.Key+ "] </b> <br /> " ;
}
this.Label1.Text = "当前网站总缓存数: " + HttpRuntime.Cache.Count + " <br /> "+str;

Dim CacheEnum As IDictionaryEnumerator = Cache.GetEnumerator()
While CacheEnum.MoveNext()
cacheItem = Server.HtmlEncode(CacheEnum.Current.Value.ToString())
Response.Write(cacheItem)
End While

IDictionaryEnumerator CacheEnum = Cache.GetEnumerator();
while (CacheEnum.MoveNext())
{
cacheItem = Server.HtmlEncode(CacheEnum.Current.ToString());
