❔ List contains 600+ lines, the file that it writes to contains only 130, why?

I got a pdf with a few pages, alot of lines, anybody got and idea? When i stop on debug, wordsInPage contains 600+ lines. that's the entire code:

using (PdfDocument document = PdfDocument.Open(@"C:\Users\myuser\Downloads\test1.PDF"))
{
    var wordsToIntercept = new List<string>();
    var pages = document.GetPages().ToList();

    foreach (var page in pages)
    {
        var wordsInPage = page.GetWords().Select(w => w.Text).ToList();
        var contains = wordsInPage.Contains("TJMAX");
        foreach (var wordd in wordsInPage)
        {
            Console.WriteLine(wordd);
        }
        string docPath =
     Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments);

        // Write the string array to a new file named "WriteLines.txt".
        using (StreamWriter outputFile = new StreamWriter(Path.Combine(docPath, "WriteLines.txt")))
        {
            foreach (string line in wordsInPage)
                outputFile.WriteLine(line.ToUpper());
        }

using (PdfDocument document = PdfDocument.Open(@"C:\Users\myuser\Downloads\test1.PDF"))
{
    var wordsToIntercept = new List<string>();
    var pages = document.GetPages().ToList();

    foreach (var page in pages)
    {
        var wordsInPage = page.GetWords().Select(w => w.Text).ToList();
        var contains = wordsInPage.Contains("TJMAX");
        foreach (var wordd in wordsInPage)
        {
            Console.WriteLine(wordd);
        }
        string docPath =
     Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments);

        // Write the string array to a new file named "WriteLines.txt".
        using (StreamWriter outputFile = new StreamWriter(Path.Combine(docPath, "WriteLines.txt")))
        {
            foreach (string line in wordsInPage)
                outputFile.WriteLine(line.ToUpper());
        }

What is the type of wordsInPage

antimatter8189OP•2y ago

List<string>

codesandplays•2y ago

cs
foreach (var wordd in wordsInPage)
        {
            Console.WriteLine(wordd);
        }

cs
foreach (var wordd in wordsInPage)
        {
            Console.WriteLine(wordd);
        }

How many lines are being print to the console?

antimatter8189OP•2y ago

130smth

codesandplays•2y ago

If list contains 600 items there is no way a for loop would print just 130 items

antimatter8189OP•2y ago

but wordsInPage.count is 600+

codesandplays•2y ago

can you share the pdf file?

antimatter8189OP•2y ago

yup thats what im having trouble undersanding https://www.analog.com/media/en/technical-documentation/data-sheets/ad9361.pdf big ass pdf, has way more then 130 lines

codesandplays•2y ago

What nuget package are you using for PDFDocument

antimatter8189OP•2y ago

codesandplays•2y ago

alright let me run this. give me a sec

antimatter8189OP•2y ago

you should see the count on 693 I think

codesandplays•2y ago

I'm getting count 693 yes

antimatter8189OP•2y ago

Thats odd aint it lol? never seen such behavior that doesn't have anything to do with the nuget, that's been extracted into a list of strings

Henkypenky•2y ago

seems like your buffer is having some problems try

using (StreamWriter outputFile = new StreamWriter(Path.Combine(docPath, "WriteLines.txt")))
        {
            outputFile.AutoFlush = true;
            foreach (string line in wordsInPage)
                outputFile.WriteLine(line.ToUpper());
        }

using (StreamWriter outputFile = new StreamWriter(Path.Combine(docPath, "WriteLines.txt")))
        {
            outputFile.AutoFlush = true;
            foreach (string line in wordsInPage)
                outputFile.WriteLine(line.ToUpper());
        }

antimatter8189OP•2y ago

on it @Henkypenky that gave me 20 more lines aka 150+ , not the 693 i should be getting

Henkypenky•2y ago

wait

codesandplays•2y ago

im getting 152 lines weird

antimatter8189OP•2y ago

yup exactly smth is so odd lol

codesandplays•2y ago

very weird

Henkypenky•2y ago

try

antimatter8189OP•2y ago

and im writing those lines just to test if i see a certain value it prob fucks up the loops after too im guessing unsure

Henkypenky•2y ago

using (StreamWriter outputFile = new StreamWriter(Path.Combine(docPath, "WriteLines.txt")))
        {
            foreach (string line in wordsInPage)
                outputFile.WriteLine(line.ToUpper());
                outputFile.Flush();
        }

using (StreamWriter outputFile = new StreamWriter(Path.Combine(docPath, "WriteLines.txt")))
        {
            foreach (string line in wordsInPage)
                outputFile.WriteLine(line.ToUpper());
                outputFile.Flush();
        }

antimatter8189OP•2y ago

back to 136 lol @Orannis aint u some c# god? save us

Henkypenky•2y ago

okay try this

try
{
 StreamWriter outputFile = new StreamWriter(Path.Combine(docPath, "WriteLines.txt");
 foreach (string line in wordsInPage)
                outputFile.WriteLine(line.ToUpper());
}
finally
{
 stream.Flush();
 stream.Close();
 stream.Dispose();
}

try
{
 StreamWriter outputFile = new StreamWriter(Path.Combine(docPath, "WriteLines.txt");
 foreach (string line in wordsInPage)
                outputFile.WriteLine(line.ToUpper());
}
finally
{
 stream.Flush();
 stream.Close();
 stream.Dispose();
}

antimatter8189OP•2y ago

waiit that code not correc tXD cant paste it in

codesandplays•2y ago

we are using "using" instead of try/finally here yearh?

antimatter8189OP•2y ago

unsure what u mean?

Henkypenky•2y ago

StreamWriter outputFile = new StreamWriter(Path.Combine(docPath, "WriteLines.txt");

try
{
    foreach (string line in wordsInPage)
    {
        outputFile.WriteLine(line.ToUpper());
    }    
}
catch (Exception e)
{
    //
}
finally
{
    outputFile.Flush();
    outputFile.Close();
    outputFile.Dispose();
}

StreamWriter outputFile = new StreamWriter(Path.Combine(docPath, "WriteLines.txt");

try
{
    foreach (string line in wordsInPage)
    {
        outputFile.WriteLine(line.ToUpper());
    }    
}
catch (Exception e)
{
    //
}
finally
{
    outputFile.Flush();
    outputFile.Close();
    outputFile.Dispose();
}

antimatter8189OP•2y ago

136 lines no change

codesandplays•2y ago

and the week has barely started fml

antimatter8189OP•2y ago

I've never seen this behavior didnt know it can even happen

Henkypenky•2y ago

i have final try

using (StreamWriter outputFile = new StreamWriter(Path.Combine(docPath, "WriteLines.txt")))
        {
            outputFile.AutoFlush = true;
            foreach (string line in wordsInPage)
                outputFile.WriteLine(line.ToUpper());
            outputFile.Close(); //outside foreach
        }

using (StreamWriter outputFile = new StreamWriter(Path.Combine(docPath, "WriteLines.txt")))
        {
            outputFile.AutoFlush = true;
            foreach (string line in wordsInPage)
                outputFile.WriteLine(line.ToUpper());
            outputFile.Close(); //outside foreach
        }

antimatter8189OP•2y ago

same result lol 136 lines only your first methode gave me +20 lines, but even that not close to the full number heh

Henkypenky•2y ago

in my behavious i saw last line was skipped flush solved it but this many lines is weird

antimatter8189OP•2y ago

skips about 550 lines insane

Henkypenky•2y ago

can you do

codesandplays•2y ago

I think i've figured it out

Henkypenky•2y ago

Console.WriteLine(wordsInPage.Count

codesandplays•2y ago

gimme a sec

Henkypenky•2y ago

before the foreach

antimatter8189OP•2y ago

LOL 693 220 302 324 253 313 400 286 285 169 264 163 162 75 288 567 756 731 631 395 377 516 418 336 392 375 484 203 387 368 503 213 884 859 773 152 i think thats page related now

Henkypenky•2y ago

did u add it inside the foreach

antimatter8189OP•2y ago

there are about 30 pages no outisde of it its in the foreach of the pages there are 30 pages in that pdf

Henkypenky•2y ago

so the 152 is working correctly

antimatter8189OP•2y ago

i dont think so it stops at first page on line 152

codesandplays•2y ago

bro here is the problem

antimatter8189OP•2y ago

not on the page that contains 152 lines

codesandplays•2y ago

your for loops are strutured weird let me explain

Henkypenky•2y ago

i think you are overwriting everything start by dismantling your problem do page 1 only

codesandplays•2y ago

henky you're right that's exactly what's happening here

antimatter8189OP•2y ago

snappp makes sense! im recreating the file each time last iteration is the 136 one prob

Henkypenky•2y ago

antimatter8189OP•2y ago

or 152 w/e lol i was sure it would be locked tho, or just add to it, not overwrite it didnt know it behaves like this good catch guys

Henkypenky•2y ago

you need to not "using" the streamwriter so: create the streamwriter do the page foreach do the lines foreach then flush close and dispose the writer

antimatter8189OP•2y ago

Will do boss thanks! helped alot wouldnt have caught it for hours by myself probably

Henkypenky•2y ago

dw, glad we could help

codesandplays•2y ago

bro your wordsinpage count is off too

cs
using UglyToad.PdfPig;
List<string> totalWords = new List<string>();

using (PdfDocument document = PdfDocument.Open(@"/Users/raghu/samplepdf.pdf"))
{
    var wordsToIntercept = new List<string>();
    var pages = document.GetPages().ToList();
    foreach (var page in pages)
    {
        var wordsInPage = page.GetWords().Select(w => w.Text).ToList();
        foreach (var word in wordsInPage)
        {
            totalWords.Add(word);
        }
    }
}

using (StreamWriter outputFile = new StreamWriter("/Users/raghu/myfile.txt"))
{
    int itemno = 1;
    foreach (string line in totalWords)
    {
        Console.WriteLine(itemno + ":" + line);
        itemno += 1;
    }
}
