Namespace: Autodesk.Revit.DB Class: WorksharingUtils

WorksharingUtils.CheckoutWorksets(Document, ICollection<WorksetId>)

Method

Description:
Obtains ownership for the current user of as many specified worksets as possible.

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.

Syntax

public static ICollection<WorksetId> CheckoutWorksets(
	Document document,
	ICollection<WorksetId> worksetsToCheckout
)

Public Shared Function CheckoutWorksets ( 
	document As Document,
	worksetsToCheckout As ICollection(Of WorksetId)
) As ICollection(Of WorksetId)

public:
static ICollection<WorksetId^>^ CheckoutWorksets(
	Document^ document, 
	ICollection<WorksetId^>^ worksetsToCheckout
)

static member CheckoutWorksets : 
        document : Document * 
        worksetsToCheckout : ICollection<WorksetId> -> ICollection<WorksetId>

Examples

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);
}

Private Sub CheckoutAllViewWorksets(doc As Document)
    Dim collector As New FilteredWorksetCollector(doc)

    ' find all view worksets
    collector.OfKind(WorksetKind.ViewWorkset)
    Dim viewworksets As ICollection(Of WorksetId) = collector.ToWorksetIds()
    Dim checkoutworksets As ICollection(Of WorksetId) = WorksharingUtils.CheckoutWorksets(doc, viewworksets)
    TaskDialog.Show("Checked out worksets", "Number of worksets checked out: " + checkoutworksets.Count)
End Sub
