Anyone have any ideas to clean this up?

```
 public string FullName
    {
        get
        {
            var fullName = new StringBuilder();
            if (FirstName.Length > 0)
                fullName.Append(FirstName);
            if (LastName.Length > 0)
            {
                if (fullName.Length > 0)
                    fullName.Append(" " + LastName);
                else
                    fullName.Append(LastName);
            }
            return fullName.ToString();
        }
    }

```
