Namespace: Autodesk.Revit.DB
Assembly: RevitAPI (in RevitAPI.dll) Version: 24.0.0.0 (24.0.0.0)
Since:  2012

Syntax

C#
public void RemoveUsers(
	Document document,
	ICollection<string> usersToRemove,
	out ICollection<string> usersActuallyRemoved
)
Visual Basic
Public Sub RemoveUsers ( _
	document As Document, _
	usersToRemove As ICollection(Of String), _
	<OutAttribute> ByRef usersActuallyRemoved As ICollection(Of String) _
)
Visual C++
public:
void RemoveUsers(
	Document^ document, 
	ICollection<String^>^ usersToRemove, 
	[OutAttribute] ICollection<String^>^% usersActuallyRemoved
)

Parameters

document
Type: Autodesk.Revit.DB..::..Document
The document containing this.
usersToRemove
Type: System.Collections.Generic..::..ICollection<(Of <(<'String>)>)>
The usernames of the users to remove.
usersActuallyRemoved
Type: System.Collections.Generic..::..ICollection<(Of <(<'String>)>)>%
The users that were successfully removed. Note that you cannot remove users who currently own any elements.

Remarks

Note that default graphic overrides will be applied to any elements owned by these users if they take ownership of any elements or worksets while they are removed. Note also that the list of removed users will be shared by all users of the central model and will remove all customizations by all users.

Examples

    // remove the users from the display settings (they will not have graphic overrides anymore)
    ICollection<String> outUserList;
    displaySettings.RemoveUsers(doc, users, out outUserList);

    // show the current list of removed users
    ICollection<String> removedUsers = displaySettings.GetRemovedUsers();
