I'm new bie to windows application..i want to search a key word inside a file..let say, if a file contains text "this is sample program...". If i search "sample" inside a file, it should give the exact matching.

------my code
FileStream fs = new FileStream("C:\ \a.txt", FileMode.Open, FileAccess.Read );
StreamReader fs1 = new StreamReader(fs );
String mystring="sampl e";

while (string == fs1. ____ )

use ReadLine() to read the file line for line and use string.IndexOf( ) to search your string within the returned string.

string line;
while ((line =ReadLine())!=n ull
{
if (line.IndexOf(" sample")!=-1)
{
//...
}
}

Hi, The need is to read each line in a text file and based on the read data decision has to be taken whether to reposition the file pointer. The StreamReader.Position does not give current position. But it gives position in multiples of 1024. Also, I am not finding a way to reposition the pointer using FileStream-StreamReader combination. Due to this the condition (FileLength = = File Position) misbehaves. I did some investigation and...

Hi. I am somewhat new to this and would like some advice. I want to search my xml file using "keyword" search and return results based on "proximity matching" - in other words, since the search string will often not produce a direct match, the results will be based on proximity (50%, 20% 100%, etc). are there any good examples out there on how to do keyword searches on XML data? How should i set up my xml file so
