Are you looking for this?
string sql = @"database.schema.table
database.schema.[table]
database.[schema].table
[database].[schema].table
 
should all be transformed to:
 
[database].[schema].[table]
";
string pattern = @"(?:\[?(\w+)\]?)?\.\[?(\w+)\]?";
Func<Match, string> replace = m =>
    (m.Groups[1].Success ? "[" + m.Groups[1].Value + "]" : "") + ".[" + m.Groups[2].Value + "]";
Console.WriteLine("{0}", Regex.Replace(sql, pattern, m=>replace(m)));
