I need to match the following full string using Regular Expression :

C# Syntax (Toggle Plain Text)
load "\fiostvmercury\Src\fiostv\server\Admin Console\Build"
load "\fiostvmercury\Src\fiostv\server\Admin Console\Build"

Re: Regular expression required

Hi

I used pattern as the below. The complete text is a multiline string and the serach pattern can occur in any of these lines. So wherever the string starts with load , I would require to print the whole line of it.

C# Syntax (Toggle Plain Text)
 
 Regex reg = new Regex(@"^load", RegexOptions.Multiline);
 Regex reg = new Regex(@"^load", RegexOptions.Multiline);

Re: Regular expression required

He,

Have a text file with the following contents :

C# Syntax (Toggle Plain Text)
Hi just a test text
load \fiostvmercury\Src\fiostv\server\Build
load \fiostvmercury\Src\fiostv\server\WFAdminConsole\Build
load "\fiostvmercury\Src\fiostv\server\Admin Console\Build"
Hi just a test text
load \fiostvmercury\Src\fiostv\server\Build
load \fiostvmercury\Src\fiostv\server\WFAdminConsole\Build
load "\fiostvmercury\Src\fiostv\server\Admin Console\Build"

Now, you can use the following code :

C# Syntax (Toggle Plain Text)
StreamReader sr = new StreamReader("D:\\ViewStorage\\cc.txt");
 
            string regmatch = @"^load";
            string output = sr.ReadToEnd();
            MatchCollection mc;
            mc = Regex.Matches(output, regmatch,RegexOptions.Multiline);
            if (mc.Count > 0)
            {
                for (int i = 0; i < mc.Count; i++)
                {
                    Console.WriteLine(mc[i].Value);
                }
            }
StreamReader sr = new StreamReader("D:\\ViewStorage\\cc.txt");
            
            string regmatch = @"^load";
            string output = sr.ReadToEnd();
            MatchCollection mc;
            mc = Regex.Matches(output, regmatch,RegexOptions.Multiline);
            if (mc.Count > 0)
            {
                for (int i = 0; i < mc.Count; i++)
                {
                    Console.WriteLine(mc[i].Value);
                }
            }

Re: Regular expression required

So, you didnt bother with the other half of my post then.
You dont seem to be debugging your code, as you dont seem to be able to show me what you found.. only that "heres some code, you look for yourself."

Re: Regular expression required

Lizr,

Thanks for your co-operation so far. The above code which was posted printed "load" thrice , but my expectation was to print the whole line starting with "load".
However, I have done away with regular expressions and is reading the text line by line using StreamReader and wherever it starts with load I get it .
May be it is not a bad idea, if I can get the regular expression to work .

Re: Regular expression required

regexpressions arent hard, but rather than just stumble about go to http://RegExpStudio.com and play with the studio product, it will help you undertand more.
