问题描述

so I have a class 'deliverables' containing information about packages information and the buyer's information. each buyer has his street and house number stored.

public Person(int id, String name, String street, int housenumber, String, postalcode, String city)

above the constructor of a person.

public Deliverable(int id, int weight, Person buyer)

above the constructor of a deliverable.

I have another class to store the deliverables and persons

public TransportCompany(){
this.myPersons = new List<Person>();
this.myDeliverables = new List<Deliverable>();
}

So I have a method to sort the myDeliverables using Bubble sort method to sort the list by the ascending order of street name if the same names then by the ascending order of houses that is odd then in the descending order of the even house numbers. here is an example:

-Id: 3, weight: 360, should be delivered at: RedNex - AAstraat 166 - 5688BX Eindhoven.

-Id: 2, weight: 700, should be delivered at: Adele - Kerkstraat 13 - 5688DE Eindhoven.

-Id: 4, weight: 360, should be delivered at: Bruno Mars - Kerkstraat 39 - 5688DE Eindhoven.

-Id: 6, weight: 900, should be delivered at: Irene Wust - Kerkstraat 20 - 5693DE Eindhoven.

-Id: 12, weight: 30, should be delivered at: Anouk - Kerkstraat 10 - 5693DE Eindhoven.

this is the current method that i am using:

public void SortForPostman()
 {
 sortedlist = Deliverables.ToList();
 sortedlist1 = Deliverables.ToList();

 int N = sortedlist.Count;

 //Select the odd house numbers
 foreach (Deliverable s in sortedlist.ToList())
 {
 if (s.Buyer.Housenumber % 2 == 0)
 {
 sortedlist.Remove(s);

 }
 }
 oddsortedlist= sortedlist;


 //Select the even house numbers
 foreach (Deliverable s in sortedlist1.ToList())
 {
 if (s.Buyer.Housenumber % 2 != 0)
 {
 sortedlist1.Remove(s);

 }
 }

 evensortedlist = sortedlist1;



 int f, d;

 N = oddsortedlist.Count;
 //filter the odd numbered list
 for (d = N - 1; d > 0; d--)
 {
 for (f = 0; f < d; f++)
 {
 if (string.Compare((oddsortedlist[f].Buyer.Street), 
 (oddsortedlist[f + 1].Buyer.Street)) == 0)
 {
 if (oddsortedlist[f].Buyer.Housenumber > oddsortedlist[f 
 + 1].Buyer.Housenumber)

 {
 swapodd(f, f + 1);
 }
 }
 else if (string.Compare((oddsortedlist[f].Buyer.Street), 
 (oddsortedlist[f + 1].Buyer.Street)) > 0)
 {
 swapodd(f, f + 1);
 }
 }
 } 

 int q, w;
 N = evensortedlist.Count;

 for (w = N - 1; w > 0; w--)
 {
 for (q = 0; q < w; q++)
 {
 if (string.Compare((evensortedlist[q].Buyer.Street), 
 (evensortedlist[q + 1].Buyer.Street)) == 0)
 {
 if (evensortedlist[q].Buyer.Housenumber < 
 evensortedlist[q + 1].Buyer.Housenumber)

 {
 swapeven(q, q + 1);
 }
 }
 else if (string.Compare((evensortedlist[q].Buyer.Street), (evensortedlist[q + 1].Buyer.Street)) > 0)
 {
 swapeven(q, q + 1);
 }
 }
 }
 sortedlist = oddsortedlist.ToList();
 sortedlist.AddRange(evensortedlist.ToList());


 int x, j;

 N = sortedlist.Count;

 for (j = N - 1; j > 0; j--)
 {
 for (x = 0; x < j; x++)
 {
 if (string.Compare((sortedlist[x].Buyer.Street), (sortedlist[x + 1].Buyer.Street)) > 0)
 {
 swapdeliverable(x, x + 1);
 }
 }
 }


 }

 public void swapdeliverable(int m, int n)
 {
 Deliverable temporary;

 temporary = sortedlist[m];
 sortedlist[m] = sortedlist[n];
 sortedlist[n] = temporary;
 }

 public void swapodd(int m, int n)
 {
 Deliverable temporary;

 temporary = oddsortedlist[m];
 oddsortedlist[m] = oddsortedlist[n];
 oddsortedlist[n] = temporary;
 }
 public void swapeven(int m, int n)
 {
 Deliverable temporary;

 te tomporary = evensortedlist[m];
 evensortedlist[m] = evensortedlist[n];
 evensortedlist[n] = temporary;
 }

So now i want to transfer this method to the object IComparer<>

namespace Deliveries
 {
 class PostmanSort : IComparer<Deliverable>
 {
 public int Compare(Deliverable x, Deliverable y)
 {
 return // The method here 
 }
 }}

and instead of using the previous method I need this

 public void SortForPostman()
 {
 PostmanSort niceway= new PostmanSort();
 TheList.Sort(niceway);
 }

c# - 我有一个冒泡排序方法，我想将它转移到另一个继承 IComarer 的类
