Saves changes that are made to a directory entry to the underlying directory store.
Assembly: System.DirectoryServices (in System.DirectoryServices.dll)
By default, changes to properties are made locally to a cache, and property values to be read are cached after the first read. For more information, see UsePropertyCache.
Changes made to the cache include changes to the properties as well as calls to Add (if this is the newly created entry).
If you call RefreshCache before calling , any uncommitted changes to the property cache will be lost.
