不要使用2个数组.

您***的方法是使用一个类来存储数据对.

Your best approach is to use a class to store pairs of data.

public class Student
{
  public string Name { get; set; }
  public int Mark { get; set; }
}

一旦您有一个学生对象数组

Once you have an array of Student objects

List<Student> students = new List<Student>();
students.Add(...);

然后您可以将名称与标记一起排序

Then you can sort the names together with the marks

var sortedStudents = students.OrderBy(s => s.Mark).ToList();
