c# - 缓存集合中元素的有效方法

Question

我试图找出缓存和检索集合中单个元素的最佳方法。
下面的代码说明了我如何能够成功地缓存列表本身。
但是当涉及到列表中的某些元素时——ContesaProperties——我无法推断出一种有效且干净的方法来做到这一点。

下面代码的第二部分----伪代码----构成了我问题的核心。

//Define Cache Keys
private const string CACHE_CONTESALIST_KEY = "ContesaList";
private const string CACHE_CONTESA_PROPERTY_KEY = @"ContesaProperty-{0}";   
.....
.....

NameValueCollection namevaluecollection = currentContext.GetCollection();
ContesaList contesaList = null;
if (Cache[CACHE_CONTESALIST_KEY] != null)
{
     contesaList = Cache[CACHE_WEBCLASSLIST_KEY] as ContesaList;
}

if (contesaList == null)
{
    contesaList = ContesaList.GetWebClassList();
    Cache.Insert(CACHE_CONTESALIST_KEY, contesaList);

}

var contesa = contesaList.First(c => c.Id.Equals(namevaluecollection["contesaElements"], StringComparison.OrdinalIgnoreCase));
if (contesa != null)
{
// Check for Contesa Properties in cache(How?); 
// if not available cache the properties within the collection where each key is 
// is suffixed with the property id.
// Begin Pseudo-Code 
//    if (thePropertiesNotInCache)
//    {
//      This takes care of first element but how to do it for all the elements?
//       Cache.Insert(String.Format(CACHE_CONTESA_PROPERTY_KEY, contesa.ContesaProperties.ToList()[0].CPropertyId), webclass.ContesaProperties.ToList()[0]);
//    }
// End Pseudo-Code
}
