stop words removal using arrays c# -

i have string array of stopwords , string array of input texts i.e.

string[] stopwords = file.readalllines(@"c:\stopwords.txt"); 

and

con.open(); sqlcommand query = con.createcommand(); query.commandtext = "select p_abstract aminer_paper pid between 1 , 500 , datalength(p_abstract) != 0";  sqldatareader reader = query.executereader();  var summary = new list<string>(); while(reader.read()) {     summary.add(reader["p_abstract"].tostring()); }  reader.close();  string[] input_texts = summary.toarray(); 

now, have use these stopwords array remove input_texts array. have used following technique not working, weird while accessing both arrays index. example, take first text @ index 0 of input_texts array i.e.

input_texts[0] 

and match word strings in stopwords array i.e.

// have match indexes of stopwords[] input_texts[0] stopwords[]    

then after removing stopwords index 0 text of input_texts array, have repeat texts in input_texts array.

any suggestions , code samples modifications highly appreciated acknowledgment.

thanks.

you can use linq this

        //string[] input_text = new string[] { "ravi kumar", "ravi kumar", "ravi kumar" };          //string[] stopwords = new string[] { "ravi" };          for(int i=0;i<input_text.count();i++)         {             (int j = 0; j < stopwords.count(); j++)             {                    input_text[i] = input_text[i].replace(stopwords[j]," ");             }         }
