示例1: RefreshDynamicFieldsAsync

		/// <summary>
		/// Removes those fields that have been removed from the categories since the last save,
		/// and adds those fields that have been added to the categories since the last save.
		/// To be sure, we assume the metadata has been changed since the folder was last saved.
		/// </summary>
		/// <returns></returns>
