Defining a Constructor in a WebService

Question

Hi, 

I need to define this code;

protected void Page_Load(object sender, EventArgs e)

    {

        using (var reader = new StreamReader(File.OpenRead(@"C:/dictionary.csv")))

        {

            while (!reader.EndOfStream)

            {

                string[] tokens = reader.ReadLine().Split(';');

                _dictionary[tokens[0]] = tokens[1];

            }

        }

    }

In a webservice but I can't get it to work. At current my code looks like this;

using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

using System.Web.Services;

using System.IO;

[WebService(Namespace = "http://tempuri.org/")]

[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]

// To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line. 

// [System.Web.Script.Services.ScriptService]

public class Service : System.Web.Services.WebService

{

    public Service() { }

    private Dictionary<string, string> _dictionary = new Dictionary<string, string>(StringComparer.OrdinalIgnoreCase);

    protected void Page_Load(object sender, EventArgs e)

    {

        using (var reader = new StreamReader(File.OpenRead(@"C:/dictionary.csv")))

        {

            while (!reader.EndOfStream)

            {

                string[] tokens = reader.ReadLine().Split(';');

                _dictionary[tokens[0]] = tokens[1];

            }

        }

    }

    [WebMethod]

    public string Translate(string input)

    {

        string output;

        if (_dictionary.TryGetValue(input, out output))

            return output;

        throw new Exception("Invalid input, please try again.");

    }

}

    

Can anyone help?
