Exceptions
ExceptionCondition
ArgumentException document is not a workshared document. -or- document is not a primary document, it is a linked document. -or- document is read-only: It cannot be modified. -or- document has an open editing transaction and is accepting changes. -or- There are one or more ids with no corresponding workset. -or- Saving is not allowed in the current application mode.
ArgumentNullException A non-optional argument was null
CentralFileCommunicationException The file-based central model could not be reached, e.g. the network is down or the file server is down.
CentralModelAccessDeniedException Access to the central model was denied due to lack of access privileges. -or- Access to the central model was denied. A possible reason is because the model was under maintenance.
CentralModelContentionException The central model are locked by another client.
CentralModelException The central model is overwritten by other user. -or- The central model is missing. -or- An internal error happened on the central model, please contact the server administrator.
CentralModelVersionArchivedException Last central version merged into the local model has been archived in the central model. This exception could only be thrown from cloud models.
InvalidOperationException Operation is not permitted when there is any open sub-transaction, transaction, or transaction group.
RevitServerCommunicationException The server-based central model could not be accessed because of a network communication error.
RevitServerInternalException An internal error happened on the server, please contact the server administrator.
Remarks

For best performance, check out all worksets in one big call, rather than many small calls.

When there comes a contention error when locking the central model, this API would wait and retry endlessly until getting the lock of the central model.

Example
Copy
void CheckoutAllViewWorksets(Document doc)
{
    FilteredWorksetCollector collector = new FilteredWorksetCollector(doc);

    // find all view worksets
    collector.OfKind(WorksetKind.ViewWorkset);
    ICollection<WorksetId> viewworksets = collector.ToWorksetIds();
    ICollection<WorksetId> checkoutworksets = WorksharingUtils.CheckoutWorksets(doc, viewworksets);
    TaskDialog.Show("Checked out worksets", "Number of worksets checked out: " + checkoutworksets.Count);
}
