关于foreach的一个BUG

//使用foreach遍历,其中未改变item的值,但是使用了匿名委托 item的值始终为rels.za.Asm的最后一位.百思不得其解,后改为for

           foreach (var item in rels.za.Asm.Count) 
           {
               var item = rels.za.Asm[i];               
               item.pone.Extend.Addonly("string-性格", RandCells(), data => {
                   List<string> sary = (List<string>)data.value;
                                 
                   string sc = "{0}是一个{1}的人。";
                   string sd = MES.Format(sc, item.pone.Name.ToString(), RandCellsms(sary));
                   return sd;
               });

               item.pone.Extend.Addonly("Appearance-长相", new WorldOne.People.Appearance(1), data =>
               {
                   WorldOne.People.Appearance aone = (WorldOne.People.Appearance)data.value;
                   return aone.ms(item.pone);
               });

               item.pone.Extend.Addonly("string-爱好", likes(item.pone), data =>
               {
                   List<string> sary = (List<string>)data.value;
                   string scc = "{0}的爱好是{1}。";
                   string sdd = MES.Format(scc, item.pone.Name.ToString(), RandCellsms(sary));
                   return sdd;
               });
           }

           for (int i = 0; i < rels.za.Asm.Count ; i++)  //使用for之后,数据读取正常
           {
               var item = rels.za.Asm[i];               
               item.pone.Extend.Addonly("string-性格", RandCells(), data => {
                   List<string> sary = (List<string>)data.value;
                                 
                   string sc = "{0}是一个{1}的人。";
                   string sd = MES.Format(sc, item.pone.Name.ToString(), RandCellsms(sary));
                   return sd;
               });
