How to check if extensions follows up in a list?

[dan sh]

Do you mean this? If file 1 and 2 are jpg, then 3 and 4 must be tif. That is: 2-2 if 5 is jpg, then 6 must be tif. That is 1-1. In short, number of consecutive jpf files must be equal to number of consecutive tif files. And these must be together. And if the order is not like the one above, then show error.

If its about Windows Explorer than I think its not possible. The sorting is simple as its string... Why error occur, if you check the extension...or I might not get your question

Yes. That's right.

It doesnt concern explorer. Basicly, the intention of this application would be to check if JPG files have their duplicate TIF files. If it would be just 1-1, then i could do it... but i cant figure this one out. And what i ment by an error was to put as an output - in which folder the files dont match.

AFAIK you just need to set up some loops wisely. Here is a bit of quick and dirty approach I could think of:

List s = new List ();
s.Add("jpg");
s.Add("tif");
s.Add("jpg");
s.Add("tif");
s.Add("jpg");
s.Add("jpg");
s.Add("tif");
s.Add("tif");
s.Add("jpg");
s.Add("tif");

    bool breakFor = false;
    int togetherCount = 1;
    for (int i = 1;i < s.Count -1;i++) {
      
      if (s\[i\] == s\[i - 1\]) {
        togetherCount++;
        continue;
      }
      else {
        int count = 0;
        while (count < togetherCount) {
          if (!(s\[i + 1\] == s\[i + count\])) {
            if (togetherCount > 1) {
              MessageBox.Show("error");
              breakFor = true;
              break;
            }
          }
          count++;
        }
        if (breakFor) {
          break;
        }
        else {
          i = i + togetherCount;
          togetherCount = 1;
        }
      }
    }

It might not be correct but good to start off I guess.

its simple then... try this

    bool Test(string dirPath)
    {
        string\[\] filePaths = Directory.GetFiles(dirPath, "\*.jpg");
        for (int a = 0; a < filePaths.Length; a++)
        {
            if (!File.Exists(Path.Combine(dirPath, Path.GetFileNameWithoutExtension(filePaths\[a\]) + ".tif")))
                return false;
        }
        return true;
    }

Umm not duplicates :/ sorry... just... the follow up files. 1.jpg has his own tif, but with a different name. example... 3.tif, because there is another 2.jpg before.

In that case, just get the count of files with JPG and count of files with TIF and they must be equal. Dump the code I had posted. Edit: There is a lot of misunderstanding going on in this post. :doh:

I already thought of that - but it is definitly a no-go. Why? Well, maybe there are some files which dont have their tifs, but some tiffs dont have their jpgs - and the count may match.

aha I got ya now. The thing you want called Stack. Last In Last Out.

Hmm... it sure looks like it's in the right way. Thanks for taking the time. I'll try to implent something similar and report what happend. Thank you

Somehow it seems i didnt implent this correctly... or it doesnt work right (like you said, it could and could not work)... aah :/

            for (int i = 0; i < DIRI.Items.Count; i++)

I would say, debug the code and find where you are wrong. Get hold of the logic and you will be done.

One thing I can figure out is you need to remoe this + 1. I have not debugged the code just read it so I may go wrong.

In today's pseudo-language that would be:

filelist=getAllFilenames()
filelist.Sort
diff=0
foreach(file in filelist) {
if (jpg) diff++
else diff--
if (diff<-1 or diff>1) error
}

Two remarks: 1. to get a natural sort order for the file names, same as Windows Explorer does, you would need to use Explorer's code, i.e. use P/Invoke and the prototype:

	\[DllImport("shlwapi.dll", CharSet=CharSet.Unicode, ExactSpelling=true)\]
	private static extern int StrCmpLogicalW(string s1, string s2);

Of course if the name part is just a number, you could use int.Parse and sort based on the outcome. 2. I cannot imagine where and how your requirement could ever have a useful application. :)

that is plain stupid. Extensions exist so files that belong together can share the name part of a filename. Use it to your advantage rather than strugging with some code to fix the mistake. :)
