.NET Quiz Question

I will post some programming language quiz questions from time to time. That's the first C# question:

public static void Main() {
  var u = new User();
  u.Name = "Tim";
  UpdateName(u, "Tom");
  Console.WriteLine(__aSyNcId_<_YMTVrkzD__quot;Name is {u.Name}");
}
	
public static void UpdateName(User user, string name) {
  user.Name = name;
}

Questions: How to print "Tom"? How to print "Tim"?
