How to sort an array of text and number ? (C#)

Hello,
I'm trying to sort an array of text and number like "12345.abcde" , I need to have it in this format and can't split it and I want to sort them. I tried Array.Sort but it has no result, also I tried a bubble sort like this:

Code (csharp):

1. while(foundone)
2.             {
3.                 foundone = false;
4.                 for(int ii = 0; ii < friends_array.Length - 1; ii++)
5.                 {
6.                     if(int.Parse(friends_array[ii]) > int.Parse(friends_array[ii + 1]))
7.                     {
8.                         temp_obj = friends_array[ii + 1];
9.                         friends_array[ii + 1] = friends_array[ii];
10.                         friends_array[ii] = temp_obj;
11.                         foundone = true;
12.                     }
13.                 }
14.             }

But it won't work neither. what shall I do ?

 

I don't quite understand what kind of sorting you need. Could you show us a sample array before and after sorting?

 

perhaps you can just sort them by their ascii code.. only problem is that . (46) < then 1 (48)

http://www.asciitable.com

I goes it shouldn't be to hard to figure out how to get the "." in the right place.

 

Code (csharp):

1.  
2. private static void Main()
3. {
4.     var before = "8375460923985.iuoeantytalmpuae";
5.  
6.     var chars = before.ToCharArray();
7.  
8.     var length1 = before.IndexOf('.');
9.     var length2 = chars.Length - length1 - 1;
10.  
11.     Array.Sort(chars, 0, length1);
12.     Array.Sort(chars, length1 + 1, length2);
13.            
14.     var after = new string(chars);
15.  
16.     Console.WriteLine("Before: {0}", before);
17.     Console.WriteLine("After : {0}", after);
18.     Console.ReadLine();
19. }
20.  

Before: 8375460923985.iuoeantytalmpuae
After : 0233455678899.aaaeeilmnopttuuy

 

Thanks ShadoX, that'd be so hard >.<
Thanks Alexzzzz I didn't mean sorting a string


Example:
Before
[567.gghj]
[345433.bgffcd]
[112233.aabbcc]

After
[345433.bgffcd]
[112233.aabbcc]
[567.gghj]

Though I found a way to get rid of that dot and it was using an array of class so I could sort it using bubblesort.
like this:

Code (csharp):

1. public class Friends {
2. public string name=""
3. public string score=""
4. }
5.  
6. public Friends[] my_list;

 

@shahroozal
Is ur problem solved?

 

probably not.. all you need to do to get the ASCII value is a cast to int...
ex.: (int) 'A' == 65

but I goes there's no need for that since alexzzzz already answered the question.

 

Create your own IComparer...

The example is a bit long winded, but it shows the idea.

 

Alexzzzz's answer was not what I was looking for though.

I solved it but the main question is still there.

Yes that's the answer! Thanks a lot JohnnyA

 

Code (csharp):

1.  
2. private static void Main()
3. {
4.     var before = new[] { "567.gghj", "345433.bgffcd", "112233.aabbcc", "98346.alkjgr", "81395.krlgjerg", "9087689.sdfew" };
5.     Console.WriteLine("Before:");
6.     foreach (var entry in before)
7.     {
8.         Console.WriteLine(entry);
9.     }
10.     Console.WriteLine();
11.  
12.     var after = before.OrderByDescending(entry => int.Parse(entry.Substring(0, entry.IndexOf('.'))));
13.  
14.     Console.WriteLine("After:");
15.     foreach (var entry in after)
16.     {
17.         Console.WriteLine(entry);
18.     }
19.     Console.WriteLine();
20.     Console.ReadLine();
21. }
22.  

Before:
567.gghj
345433.bgffcd
112233.aabbcc
98346.alkjgr
81395.krlgjerg
9087689.sdfew

After:
9087689.sdfew
345433.bgffcd
112233.aabbcc
98346.alkjgr
81395.krlgjerg
567.gghj

 

That's so clever ! thanks man.
