c# - what's the correct way to use locking in AppFabric -

i've got service updates appfabric cache 8000 objects every 4 hours. read table, creates object every record , stores in cache.

while cache being updated 1 object @ time consumers can still request objects cache. there's not information available this, want know if following code correct way lock , store cache objects in appfabric while other threads can query cache:

// caching part private static void cachedealers(dictionary<key<string>, dealer> dealers) {   datacache cache = cache.instance.dealercache;    foreach (key<string> key in dealers.keys) {     cacheobject(cache, key.tostring(), dealers[key], mdealerregionname);   } }      private static void cacheobject(datacache cache, string key, object obj, string region)     {       datacachelockhandle lockhandle;        if (cache.getandlock(key, timespan.fromseconds(10), out lockhandle) == null)       {         cache.put(key, obj, timespan.maxvalue, region);       }       else       {         cache.putandunlock(key, obj, lockhandle, timespan.maxvalue, region);       }     }      // retrieve part     public dealer getdealer(string lab, string number) {       dealer dealer = (dealer)cache.instance.dealercache.get(new key<string>(lab, number).tostring(), mdealerregionname);       return dealer;     } 

a locked item can still read cache (though while it's locked return original object, not updated one), getdealer method should continue work while cache being updated. msdn:

regular method calls not blocked , access latest version of cached object
