RemoveUsers Method

Removes users from the list of displayed users and permanently discards any customization of the graphics. Note that a user cannot be removed if he or she owns any elements.

Namespace: Autodesk.Revit.DB
Assembly: RevitAPI (in RevitAPI.dll) Version: 17.0.0.0 (17.0.484.0)
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 String
The usernames of the users to remove.
usersActuallyRemoved
Type: System.Collections.Generic ICollection 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

Copy C# 
public void RemoveAndRestoreUsers(Document doc)
{
    // get or create a WorksharingDisplaySettings current active document
    WorksharingDisplaySettings displaySettings = WorksharingDisplaySettings.GetOrCreateWorksharingDisplaySettings(doc);

    // get all users with GraphicOverrides
    ICollection<String> users = displaySettings.GetAllUsersWithGraphicOverrides();

    // 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();

    String message = "Current list of removed users: ";
    if (removedUsers.Count > 0 )
    {
       foreach (String user in removedUsers)
       {
          message += "\n" + user;
       }
    }
    else
    {
        message = "[Empty]";
    }

    TaskDialog.Show("Users Removed", message);

    // restore the previously removed users
    int number = displaySettings.RestoreUsers(outUserList);

    // again, show the current list of removed users
    // it should not contain the users that were restored
    removedUsers = displaySettings.GetRemovedUsers();

    message = "Current list of removed users: ";
    if (removedUsers.Count > 0 )
    {
       foreach (String user in removedUsers)
       {
