Changes the identity of the connected session to the identity specified without creating a new session (OPC 10000-4, ActivateSession).

public void ChangeUserIdentity(OpcUserIdentity identity)

Public Sub ChangeUserIdentity(identity As OpcUserIdentity)

Parameters

Name	Type	Description
identity	OpcUserIdentity	The OpcUserIdentity to use from now on or a null reference (Nothing in Visual Basic) to continue as an anonymous user.

Exceptions

Exception	Condition
InvalidOperationException	The method is currently not supported, because of the license has expired.
ObjectDisposedException	The object has been disposed of.
OpcException	The client is not connected (BadServerNotConnected) or the server rejected the identity, for example with BadUserAccessDenied or BadIdentityTokenRejected.

Remarks

On success the identity is also applied to the UserIdentity, so a later reconnect uses it too. If the server rejects the identity, the UserIdentity remains unchanged.
