Answer 1

花括号要“转义”一下
string str = string.Format(@"  Timer {0} = new Timer();              {0}.Interval = 1000;              {0}.Start();              {0}.Elapsed += new ElapsedEventHandler({0}_Elapsed);     static void {0}_Elapsed(object sender, ElapsedEventArgs e)          {{                        }}", "a");
