Open Text File And Sort

[nullified]

Hi,

I want to open a text file and read the data then sort it via date.

i found some stuff already that helps but im new to this and if anyone point me in the right direction it would be very appreciated.

this sample app here http://www.c-sharpcorner.com/UploadFile/mmehta/OpeningandViewingTextandImageFiles12082005060630AM/OpeningandViewingTextandImageFiles.aspx

opens the text file exactly how i want it to, i would just like to have the data sorted by date also. And eventually i would like to add color coding to the IP's and 32 digit numbers.

here is a sample of what the text file would look like....

any help is greatly appreciated

Hi, if every line starts with the date, this should do the trick:

List<string> lines = new List<string>();
using (StreamReader r = new StreamReader(new FileStream(Environment.GetFolderPath(Environment.SpecialFolder.Desktop) + @"\data.txt", FileMode.Open)))
{
	string line;
	while ((line = r.ReadLine()) != null)
	{
		lines.Add(line);
	}
				
}
lines.Sort();

sorry im very noobish at this....

Anyone got any ideas on this one

[Ramy Mahrous]

I think _r0ckbaer answered you!!

[nullified]

i also have a second question

its after his answer in case you missed it.....

[iamthwee]

>if every line starts with the date

Not entirely sure if that would work all the time, especially seeing as some dates can be written as DD-MM-YYYY or YYYY-MM-DD etc. A cast iron solution would be to convert the date to a date object and use the sort methods associated with that.

[nullified]

the date format is always the same for what i am doing...

e.g.

MM-DD-YYYY

[iamthwee]

the date format is always the same for what i am doing...

e.g.

MM-DD-YYYY

in that case _r0ckbaer's solution will fail.

I am so close its not funny........

ive done what you suggested and when i build the application and try to open a text file it says this is not a valid image.the only message i get in express is;

Field 'FileDisplay.windows_forms.components' is never assigned to, and will always have its default value null

Ill inlcude the code to show you what i have

            DateTime dt2 = DateTime.ParseExact(s2.Substring(1, 19), dateFormat, null);

When you catch the exception you should output its message, and not "blabla..is not a valid image file". That way you'll be able to identify what's going wrong.

[nullified]

I identified the debugger error....apart from that it is out of my league :)

but i got it working and it does what i want so i'll quit while im ahead i think :)

here is a link to the code for future reference....or for anyone thats interested.

Just for the gallery, see first part of code in my previous post:

string format = "MM.dd.yyyy HH:mm:ss";
            lines.Sort(new Comparison<string>(delegate(string a, string b)
                                                  {
                                                      string dateA = Regex.Match(a, "\\[(.+)\\]").Groups[1].Value;
                                                      string dateB = Regex.Match(b, "\\[(.+)\\]").Groups[1].Value;

                                                      return (DateTime.Compare(DateTime.ParseExact(dateA, format, null),
                                                          DateTime.ParseExact(dateB, format, null)));
                                                  }));
