If it's the second line, you can read a line at a time and use the second one. Or you can use a regex to parse the data.

System.IO.File.ReadXXX is the group of methods that are the easiest way to read a file into a string or group of strings.

Sorry for the troublesome! This is some of my code which i only manage to get title as return. May i have some advice on it? Private Function ReadTextFile(ByVal sFileName As String) As String Dim s As String = String.Empty Try Dim oFile As FileStream = New FileStream(sFileName, FileMode.Open, FileAccess.Read, FileShare.Read) Dim oReader As StreamReader = New StreamReader(oFile) s = oReader.ReadLine() oReader.Close() oFile.Close() ReadTextFile = s Catch ReadTextFile = "Unable to open file." End Try End Function

Your problem is that you're only reading the first line of the file. The ReadLine call needs to be a recurrent call, based on the return value of the method. e.g. (from MSDN) Dim input As String input = sr.ReadLine() While Not input Is Nothing 'Do something with the input 'Read the next line of input input = sr.ReadLine() End While This will continue to read the file until there is no further input returned by the ReadLine() call. Then you'll have to compare the returned input string to whatever you want to catch, either using a regex or a string constant (in the case of a marker string or something that won't change) to get the particular peice of info you're after. I would add do it something like this... Dim input As String input = sr.ReadLine() While Not input Is Nothing If (input.CompareTo(stringConstant) = 0) 'do whatever with the data input = Nothing Else input = sr.ReadLine() End If End While
