CheckoutWorksets Method (Document, ICollection(WorksetId))

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

Namespace: Autodesk.Revit.DB
Assembly: RevitAPI (in RevitAPI.dll) Version: 17.0.0.0 (17.0.484.0)
Since: 2014

Syntax

C# 
public static ICollection<WorksetId> CheckoutWorksets(
	Document document,
	ICollection<WorksetId> worksetsToCheckout
)
Visual Basic 
Public Shared Function CheckoutWorksets ( _
	document As Document, _
	worksetsToCheckout As ICollection(Of WorksetId) _
) As ICollection(Of WorksetId)
Visual C++ 
public:
static ICollection<WorksetId^>^ CheckoutWorksets(
	Document^ document, 
	ICollection<WorksetId^>^ worksetsToCheckout
)

Parameters

document
Type: Autodesk.Revit.DB Document
The document containing the worksets.
worksetsToCheckout
Type: System.Collections.Generic ICollection WorksetId
The ids of the worksets to attempt to check out.

Return Value

The ids of all specified worksets that are now owned, including all that were owned prior to the function call.

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.

Examples

Copy C# 
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);
}
Copy VB.NET 
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
