数组操作简单写法

       // var bodyList = workPart.Bodies.ToArray().ToList().ConvertAll(body => body.Tag).ToArray();//等价于        Part workPart = thesession.Parts.Work;//获取当前工作部件        var bodyList= workPart.Bodies.ToArray();//var 动态的变量类型        Tag[] bodies = new Tag[bodyList.Length];//tag 一种变量类型 里面放整数值 tag已经被封住过        for (int i = 0; i < bodyList.Length; i++)//数组初始化        {            bodies[i] = bodyList[i].Tag;        }
