Re: reading a file from a specified place

In this case I would load all the string data into a variable so you can use the StringReader class (in System.IO).

The StringReader object lets you read a text file line by line. So you could scan through the lines in search of your delimeters and only read the lines in between when you have found the appropriate start and stop reading when it finds the end.

Re: reading a file from a specified place

A standard piece of code I find myself using and reusing, time and time again...

C# Syntax (Toggle Plain Text)
using ( FileStream fileStream = File.OpenRead(CONFIG_PATH) ) {
                Regex entryRegex = new Regex(@"^\s*(?<name>\S+?)\s*\:\s*(?<value>.+?)\s*$", RegexOptions.Compiled | RegexOptions.IgnoreCase);
 
                using ( StreamReader reader = new StreamReader(fileStream) ) {
                    while ( (line = reader.ReadLine()) != null ) {
                        if ( entryRegex.IsMatch(line) ) {
...
using ( FileStream fileStream = File.OpenRead(CONFIG_PATH) ) {
                Regex entryRegex = new Regex(@"^\s*(?<name>\S+?)\s*\:\s*(?<value>.+?)\s*$", RegexOptions.Compiled | RegexOptions.IgnoreCase);

                using ( StreamReader reader = new StreamReader(fileStream) ) {
                    while ( (line = reader.ReadLine()) != null ) {
                        if ( entryRegex.IsMatch(line) ) {
...
