Word count of an uploaded document??

Question

Hello -

I am beginner and learning asp.net and C#.

I am trying to develop an web application which has to count the number of words in an uploaded document using file upload control.

Type of files it should allow to upload are word,excel,powerpoint,pdf,rtf and txt.

For example if i upload a word document it should save in a default location on server, latter should show me the number of words available in that document.

I am using Visual Web Developer 2005/2008.

Please help me how to do this application.

Thank you.

Hi, To save a uploaded file in default location you have to give file path explicitly as below. FileUpload.SaveAs(filepath); //[file path contains your default file path] To count no of words refer the following code...it may help..code is in c# ... StreamReader sr=new StreamReader(filepath); String all=sr.ReadToEnd(); sr.Close(); char[] chararray = {' ' , ',' , '
' , '	' , '\f'}; // [put all possible chars which all are used to separate a word in this char array] String[] strarray = all.Split(chararray); int wordcount = strarray.Length; wordcount contains no of words... But up to my Knowledge word,excel,pdf ,power point documents are contains some extra char and delimiters and other special char based on their format... txt and rtf file can be readed easily using above code.

Hi prakash, Its difficult to find word count for MS word and excel files... we can find its word count but it may not be correct.. because with our text, microsoft add some more technical info and chars in those files... so it leads to wrong info. [ they add 10+ lines info for blank file too] May i know for which purpose you need this...

If not all file types. Can you please let me know how to count the number of words in a word document uploaded on to the server using upload control in asp.net. Thank you

Well, that is tall order. You have listed several different file types and the utility of knowing the word count is unknown to me. You may wish to consider looking at the file size a metric rather than the word count. To get the word count you'd need to open each file and look at the text (less the formatting). Once you have the text, these functions might help you: /// /// This is generally the most accurate approach to /// parsing a body of text into sentences to include /// the sentence's termination (e.g., the period, /// question mark, etc). This approach will handle /// duplicate sentences with different terminations. /// /// /// /// private ArrayList SplitSentences(string sSourceText) { // create a local string variable // set to contain the string passed it string sTemp = sSourceText; // create the array list that will // be used to hold the sentences ArrayList al = new ArrayList(); // split the sentences with a regular expression string[] splitSentences = Regex.Split(sTemp, @"(? /// Calls the SplitSentences (best approach) method /// to split the text into sentences and displays /// the results in a list box /// /// /// private void btnParseBest_Click(object sender, EventArgs e) { lstSentences.Items.Clear(); ArrayList al = SplitSentences(txtParagraphs.Text); for (int i = 0; i /// Generate the total character count for /// the entire body of text as converted to /// one string /// /// /// int count of all characters public int GenerateCharacterCount(string allText) { int rtn = 0; // clean up the string by // removing newlines and by trimming // both ends string sTemp = allText; sTemp = sTemp.Replace(Environment.NewLine, string.Empty); sTemp = sTemp.Trim(); // split the string into sentences // using a regular expression string[] splitSentences = Regex.Split(sTemp, @"(? /// Generate a count of all words contained in the text /// passed into to this function is looking for /// an array list as an argument; the array list contains /// one entry for each sentence contained in the /// text of interest. /// /// /// int count of all words public int GenerateWordCount(ArrayList allSentences) { // declare a return value int rtn = 0; // iterate through the entire list // of sentences foreach (string sSentence in allSentences) { // define an empty space as the split // character char[] arrSplitChars = {' '}; // create a string array and populate // it with a split on the current sentence; // use the string split option to remove // empty entries so that empty sentences do not // make it into the word count. string[] arrWords = sSentence.Split(arrSplitChars, StringSplitOptions.RemoveEmptyEntries); rtn += arrWords.Length; } // return the final word count return rtn; } /// /// Return a count of all of the sentences contained in the /// text examined; this method is looking for a string /// array containing all of the sentences; it just /// returns a count for the string array. /// /// /// public int GenerateSentenceCount(string[] allSentences) { // create a return value int rtn = 0; // set the return value to // the length of the sentences array rtn = allSentences.Length; // return the count return rtn; }
