String Array Sort Problem

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3. using System.Collections.Generic;
4. using System.Linq;
5. using System;
6.  
7.  
8. public class CompareStrings : IComparer<string>
9. {
10.     // Because the class implements IComparer, it must define a
11.     // Compare method. The method returns a signed integer that indicates
12.     // whether s1 > s2 (return is greater than 0), s1 < s2 (return is negative),
13.     // or s1 equals s2 (return value is 0). This Compare method compares strings.
14.     public int Compare(string s1, string s2)
15.     {
16.         return string.Compare(s1, s2, true);
17.     }
18. }
19.  
20. public class testSort : MonoBehaviour
21. {
22.     public GameObject[] gos;
23.     public string[] unsortedArray;
24.  
25.     void Update()
26.     {
27.         if(Input.GetKeyDown(KeyCode.A))
28.         {
29.             unsortedArray = new string[gos.Length];
30.             for(int i = 0; i < gos.Length; i++)
31.             {
32.                 unsortedArray[i] = gos[i].name;
33.             }
34.  
35.  
36. //            Array.Sort(gos, delegate(GameObject x, GameObject y)
37. //                {
38. //                    return String.Compare(x.name, y.name);
39. //                });
40.            
41.  
42.         var sortedArray = unsortedArray.OrderBy(a => a, new CompareStrings());
43.  
44. //            IEnumerable<GameObject> gosQuery =
45. //                from go in gos
46. //                orderby go ascending
47. //                select go;
48.  
49.             foreach(var element in sortedArray)
50.             {
51.                 Debug.Log(element);
52.             }  
53.         }
54.     }
55. }
56.  

I want to do Exactly the same things with hierarchy's alpha sort,

however the output is not the same,

i have tried a lot of function that found on internet and MSDN

such as delegate(T x, T y)
return String.Compare(x.name, y.name)

and exactly copy from Unity API with alpha sort,

However the output is not what i want.

I don't why, Help me PLZ!!!!

PS: The output what i want is 1-> 2->3 ......25 > 26

 

You should have posted that first picture as code box, not picture. Now i can't copy-paste

But maybe:

Code (CSharp):

1. return string.Compare(s1, s2, System.StringComparison.Ordinal);

 

Updated, its doesn't work, same output

 

The problem here is that the sorting is treating your numeric values as strings not numbers.

There is a comparer here which might do what you are trying to achieve:

There also appears to be a discussion on this problem here:

You have it done so far already, i feel like it just comes down to this:

Code (CSharp):

1.     public int Compare(string s1, string s2)
2.     {
3.         return string.Compare(s1, s2, true);
4.     }

"Ordinal" usually means numeric, but seems like it means different thing here for C#. You'll have to change that line other way then.

Is it "AlphaNumeric" comparison or just "Numeric" you are after? You may get simpler answer if it's just numeric. Convert s1 and s2 to number and return value based on them.

 

I believe the problem here is that the values are alphanumeric and therefore cannot be converted to numbers.
