First of all, this is Tessnet2, see http://www.pixel-technology.com/freeware/tessnet2/[^].

Wikipedia points out some more .NET projects related to Tesseract, see http://en.wikipedia.org/wiki/Tesseract_%28software%29#Libraries_using_Tesseract_engine[^].

I tried native Tesseract and Tessnet2, was not satisfied with the quality at all.

I tries some much more promising works, but all of them are incomplete. Please see my past answer: OCR Software[^].

Bitmap image = new Bitmap("eurotext.tif");
tessnet2.Tesseract ocr = new tessnet2.Tesseract();
ocr.SetVariable("tessedit_char_whitelist", "0123456789"); // If digit only

ocr.Init(@"C:\Users\MyUserName\Desktop\tessdata", "eng", true); // To use correct tessdata
Console.WriteLine("!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!1");
List<tessnet2.word> result = ocr.DoOCR(image, Rectangle.Empty);
foreach (tessnet2.Word word in result)
Console.WriteLine("{0} : {1}", word.Confidence, word.Text);

I got error at the line where ocr.init() is and I don't know what to do.it says ocr.init takes as first argument tessdata, second argument as string language and as third argument boolean. I couldn't find the answer this problem for days.I tried every tessdata in tesseract site.can you help to use this tessnet2.dll

Try install tessdata (you can find it in Program Files folder) for Tessnet2 version not Tessnet3.

Thank you for the note.
I tries Tessnet (I think Tessnet2), it works, but I was frustrated with the quality...
