[DataMemberAttribute(Order=60)] 
public Nullable<bool> HasChanged { get; set; }

속성 값

Type: Nullable<Boolean>
true if metadata item has changed since the last query; otherwise, false.

설명

When metadata is retrieved using RetrieveMetadataChangesRequest, with a valid ClientVersionStamp parameter, the RetrieveMetadataChangesResponse. EntityMetadata property contains an EntityMetadataCollection of all the changed metadata. When a child item has changed but a parent item has not, the HasChanged property of the child will be true but for the parent it will be false.

It is not valid to use this attribute as part of a query because the value is calculated. The value will be null except in the results of a query that returns information about changes from a previous query.
