string comparison

[Lakshmi prabha]

Im new to .net i doing my project in .net

I need a code for reading a text file and store every string in to an array. Check the array by giving some word.

If the word is found then the full line which the word
contains is store in to a text boxes

To check if str2 is a substring of str1 (that is, str1 contains str2), use the following line:

if (str1.Contains(str2))
    //put code here

I hope this helps you.
