I am trying to read a text file and extract a clause/ sentence containg specific words from the file .


using System;
using System.Text.RegularExpressions;

public class Example
{
   public static void Main()
   {
      string pattern =@"(?<=^|\.)[^.]*?(? =\bshall incure to all bank of amrerica Affiliates\b).*(\.|$)"
      string input = "anita singh is good girl.Supplier expressly acknowledges and agrees that the rights and obligations of Bank of india set forth in this Agreement shall inure to all Bank of india Affiliates.anita is a good girl." ;
      Match match = Regex.Match(input, pattern);
      if (match.Success)
      {
         Console.WriteLine("Match: " + match.Value);
      } 
   }
}



output would be


Supplier expressly acknowledges and agrees that the rights and obligations of Bank of India set forth in this Agreement shall inure to all Bank of india Affiliates.

shall incure to all bank of amrerica Affiliates
shall inure to all Bank of india Affiliates

The fact that your search string doesn't have a match indicates to me you have never run this code. Homework ?

sorry its india insted of america

I found this as a possible solution. I know I'm keeping it around from now on.

public static bool ExactMatch(string input, string match)
{
    return Regex.IsMatch(input, string.Format(@"\b{0}\b", Regex.Escape(match)));
}

thanks trying to ckeck if it works
Make your life easier and split the string into sentences first.

Example:
var regex = new Regex(@".*your text goes here.*");
var text = "This is a Test 2. This is the sentence with 'your text goes here' xyz. The middle sentence is the one we want.";

var texts = text.Split('.');
foreach(var t in texts) {
   if(regex.IsMatch(t)) {
      Console.WriteLine(t.Trim());
   }
}

Thanks the code works fine but what if there is text file called contract.txt and somewhere in the text file "your text goes here" is written .

How to extract it ?

You just read the file into a string. Either line by line or the complete file at once. This pretty much depends what you want to use it for. If your file isn't that big reading the whole file into memory shouldn't be an issue.
