VersionCol Remove Method

Call object.Remove(index)
Call object.Remove(objectId)
Call object.Remove(objectVersionId)

The Remove method syntax has the following parts.

Part	Description
Object	The version collection.
Index	The index of the item to be removed from the collection.
ObjectID	The object identifier for the object version or workspace to be removed from the collection. You can supply an objectID only for the Versions-of-Workspace collection, the Workspaces-of-Version collection, or the Checkouts-of-Workspace collection.
ObjectVersionID	The object-version identifier for the item to be removed from the collection. You can supply an objectVersionID for any version collection.

There are many different kinds of object-version collections. You can apply this method to some of them, but not to others. This method works for:

Target-Versions collections. You can use this method to reduce the set of versions of a particular target object that are related to a particular source object.
Versions-of-Workspace collections. You can use this method to remove an object version from the set of items contained in the workspace.

This method fails for:

Predecessor-Versions collections. To enlarge an object version's set of predecessors, use the MergeVersion method of the RepositoryObjectVersion object.
Successor-Versions collections. To enlarge an object version's set of successors, use the CreateVersion method of the RepositoryObjectVersion object.
Versions-of-Object collections. To enlarge an object's set of versions, use the CreateVersion method of the RepositoryObjectVersion object.
Workspaces-of-Version collections. To remove a workspace from the set of workspaces in which an object version is present, you must explicitly remove the object version from that workspace's Versions-of-Workspace collection.
Checkouts-of-Workspace collections. To reduce the number of items checked out to a workspace, use the Checkin method of the RepositoryObjectVersion object.
