Regular Expression Class problems

Question

Hi all,

I'm having problems understanding errors within a RegEx class I've got: (Please bare with me, I'm not an experienced C# programmer).

The class works (or did work when passing arguments from the command line using the .exe generated by the class.

What I have try to do is pass the class string values directly from the program page itself.

Here is the program page:

using System;

using System.IO;

using System.Collections.Generic;

using System.Text;

using System.Text.RegularExpressions;

namespace RegEx_TestCApp_Recipe02_05

{

class Program

{

const String REGEX_STRING_VALUE = @"^[\w-]+@([\w-]+\.)+\w-]+$ ";

const String REGEX_STRING_EMAIL = @"[email protected]";

//string line;

//Readline

static void Main(string[] args)

{

//Console.WriteLine(REGEX_STRING_VALUE);

//System.Threading.Thread.Sleep(10000);

Recipe02_05 Receipe_Class_test;

// (@"^[\w-]+@([\w-]+\.)+\w-]+$ [email protected]");

Receipe_Class_test = new Recipe02_05(REGEX_STRING_VALUE + REGEX_STRING_EMAIL);

//Receipe_Class_test = new Recipe02_05();

//Receipe_Class_test.(REGEX_STRING_VALUE, REGEX_STRING_EMAIL);

//Console.WriteLine("Regular Expression: {0}", args[0]);

//Console.WriteLine("Input: {0}", args[1]);

//Console.WriteLine("Valid = {0}", ValidateInput(args[0], args[1]));

//Console.WriteLine("\nMain method complete. Press Enter");

//Console.ReadLine();

}

}

}

Here is the Class page

using System;

using System.Text.RegularExpressions;

namespace RegEx_TestCApp_Recipe02_05

{

class Recipe02_05

{

/*

// Alternative version of the ValidateInput method that does not create Regex instances.

public static bool ValidateInput(string regex, string input)

{

// Test if the specified input matches the regular expression.

return Regex.IsMatch(input, regex);

}*/

public static bool ValidateInput(string regex, string input)

{

// Create a new Regex based on the specified regular expression.

Regex r = new Regex(regex);

// Test if the specified input matches the regular expression.

return r.IsMatch(input);

}

//public static void Main(string[] args)

//{

// Test the input from the command line. The first argument is the

// regular expression, and the second is the input.

//Console.WriteLine("Regular Expression: {0}", args[0]);

//Console.WriteLine("Input: {0}", args[1]);

//Console.WriteLine("Valid = {0}", ValidateInput(args[0], args[1]));

// Wait to continue.

//Console.WriteLine("\nMain method complete. Press Enter");

//Console.ReadLine();

//}

}

}
