search for str in file [resolved]

I am kind of new to vb.net, im an old vb6 pro :)

Im having issues writing code to search for a string within a file. Mainly, I really dont know much about the new file handling features of vb.net.


Example:

searchString = "red"

Contents of file to search:

<font color="red">

Any help is greatly appreciated.

I dont have a IDE here but...

VB Code:

Imports System.IO ' for StreamReader
 
'-----
 
Public Function SearchFile(FileName as String, SearchString as String) as Boolean
 
Dim sr as new StreamReader(FileName)
 
Dim strLines() as String = sr.ReadToEnd.Split(vbcrlf)
 
sr.Close
sr = nothing
 
Dim intIndex as Integer '
 
For Each s as String in strLines
    intIndex = s.IndexOf(SearchString )' IndexOf returns -1 if the string not found
    If not intIndex = -1 Then
       Return True
    End If
Next

This simple method returns true if the file contains the SearchString (it does not continue looking after it finds a match.

VB Code:

'usage
 
Msgbox (SearchFile("c:\test.txt", "red"))

thanks.... that helps..
