By Jon Skeet:

public bool ReflectiveEquals(object first, object second)
{
    if (first == null && second == null)
    {
        return true;
    }
    if (first == null || second == null)
    {
        return false;
    }
    Type firstType = first.GetType();
    if (second.GetType() != firstType)
    {
        return false; // Or throw an exception
    }
    // This will only use public properties. Is that enough?
    foreach (PropertyInfo propertyInfo in firstType.GetProperties())
    {
        if (propertyInfo.CanRead)
        {
            object firstValue = propertyInfo.GetValue(first, null);
            object secondValue = propertyInfo.GetValue(second, null);
            if (!object.Equals(firstValue, secondValue))
            {
                return false;
            }
        }
    }
    return true;
}

More compact and modern syntax:

public bool ReflectiveEquals(LocalHdTicket serverTicket, LocalHdTicket localTicket)
  {
     if (serverTicket == null && localTicket == null) return true;
     if (serverTicket == null || localTicket == null) return false;

     var firstType = serverTicket.GetType();
     // Handle type mismatch anyway you please:
     if(localTicket.GetType() != firstType) throw new Exception("Trying to compare two different object types!");

     return !(from propertyInfo in firstType.GetProperties() 
              where propertyInfo.CanRead 
              let serverValue = propertyInfo.GetValue(serverTicket, null) 
              let localValue = propertyInfo.GetValue(localTicket, null) 
              where !Equals(serverValue, localValue) 
              select serverValue).Any();
  }
