定义了一个类变量,它是一个集合,并初始化为ArrayList类型,集合保存的是Student对象,<Student>这是泛型用法,这样在其他地方给students添加内容时只能添加Student对象
List<int> newStudents =newList<int>();for(inti =0; i < students.Count; i++) {if(students[i] ==1) newStudents.Add(students[i]); } 你看,这种以暴制暴的方式往往就是这么枯燥、无趣。 知识点来了!!! 由于我们声明了一个 newStudents 的泛型对象,这个对象在初始化的时候,默认大小是多少?正确...

List<T>是泛型集合这种集合规定了集合内的数据类型,只能存放<T>的T类型数据;而ArrayList不是泛型,这种集合中可以存放任意类型数据;举个简单例子:List<Student> students=new List<Student>(); 那么读取数据时就不用类型转化了,即:Student stu=st...
