Read or modify the session properties

You can change the session user and session locale. You can also run methods at the user change event.

To change the session user, use Session.ChangeUserto authenticate another user in the session. The user name and password are passed as arguments bool ChangeUser(string username, string password); .
To change the session locale, create a string array by using the new string[] syntax.

Important: Be sure to create an array. The session requires a fallback locale.
This example illustrates how to set the locale to international English.
```
Session.LocaleId = "en-US";
```
To run methods at the user change event, use the UserChange event handler, supplied by the Session class.

Important: Always cancel the subscription in the Stop() method to avoid a memory leak.
This example illustrates how to have the Session_UserChange method executed at each user change, until cancellation of the subscription.
```
public override void Start()
{
    Session.UserChange += Session_UserChange;
}

private void Session_UserChange(object sender, UserChangeEventArgs e)
{
    Log.Info(e.newUser.BrowseName);
}

public override void Stop()
{
    Session.UserChange -= Session_UserChange;
}
```
The method generates a log that contains the BrowseName of the new user

The UserChangeEventArgs data type is a class that displays these properties:

newUser

Represents new user nodes.

oldUser

Represents old user nodes.
