How to get current logged user in event receivers?

Question

I need to get the information about the user actually logged (as SPUser) inside an event receivers.

The following line:

Dim currentUser As SPUser = SPContext.Current.Web.CurrentUser

does not work because Current is set to Nothing (null).

I read around that this is due to the asynchronous nature of event receivers but then, how to get the user information I need?

EDIT: I am using ItemCheckingIn receiver to try block a user to check in a file checked out by another user.

Thank you in advance for any help

SPContext will not be available in EventReceiver, hence your Current is returning null.. instead use Properties — Gaurravs, Mar 28 '16 at 08:51

Use this:

public override void ItemCheckingIn(SPItemEventProperties properties)
{
    base.ItemCheckingIn(properties);
    var currentUser = properties.Web.CurrentUser;
}

As you can see, properties object contain SPWeb, that have CurrentUser property.

Use the synchronous method in your event receiver, and you should be able to retrieve the current user from the context.

Thank you for the fast answer. I edited my question to give more details. I am not sure I can use a synchronous event receiver to implement this logic, or yes? – Drake Sep 07 '10 at 10:27
Synchronous is the only way to go if you want to stop an operation, as you are doing. Strange however, as CurrentContext should be available at this stage... – James Love Sep 07 '10 at 10:51

Have you also tried properties.CurrentUserId? – James Love Sep 07 '10 at 11:06
Yes, it worksm thank you! Do you also know how to get SPUser from a CurrentUserId? – Drake Sep 07 '10 at 12:19

No worries - SPWeb.Users.GetByID() I believe. – James Love Sep 07 '10 at 12:21
This answer is misleading - it suggests that when Receiver is set to Synchronous then SPContext.Current != null which is not true. properties.CurrentUserId is also available when Receiver is not set to Synchronous but in either case it doesn't return SharePoint user ID but some internal number. – Mariusz Ignatowicz Aug 08 '14 at 14:28

You can use this code.

using (SPSite originalsite = new SPSite(properties.SiteId, properties.OriginatingUserToken))
{
  //To get the current user
  using (SPWeb web = originalsite.OpenWeb())
  {
    string strUserName = web.CurrentUser.LoginName.ToString();
  }
}

With 2010, the event property bag contains the OriginatingUserToken ,UserDisplayName , and UserLoginName, which you can use to get the original user.

Check the section 5. Impersonation enhancements here : http://extreme-sharepoint.com/2011/12/27/event-receivers-sharepoint-2010/

Not 100% sure what the behaviour is with async event receivers, but did you have a look at

WindowsIdentity windowsIdentity = WindowsIdentity.GetCurrent();
