    public class Service1 : System.Web.Services.WebService
    {

        [WebMethod]
        public string Main(string[] args)
        {
            string host = "localhost";
            string database = "articles";
            string user = "root";

            try
            {
                MySqlConnection mysqlCon = new MySqlConnection(strProvider);
                mysqlCon.Open();
                

                if (mysqlCon.State.ToString() == "Open")
                {

                    Console.WriteLine("------------------------");

                    MySqlCommand mysqlCmd = new MySqlCommand(strSQL, mysqlCon);
                    MySqlDataReader mysqlReader = mysqlCmd.ExecuteReader();
                   

                   Console.WriteLine("Id\tName\tLastName");
                   Console.WriteLine("------------------------");

                    while (mysqlReader.Read())
                    {
                        Console.WriteLine(mysqlReader.GetInt32(0) + "\t" + mysqlReader.GetString(1) + "\t" + mysqlReader.GetString(2));
                        
                        
                    }

Can the Console class even be used in web services?

You can return any object of array of objects (except for certain objects that implement certain interfaces, like IDictionary) from a web service.

If you're using it in a windows application then the web reference you create to connect with the service, this reference generates the objects used for input parameters and return values if they don't already exist (no need to generate a string class for example).

If you're using it for an ASP.Net service then the same thing applies, but these classes are generated in javascript, all you have to do then is have a scriptmanager that correctly references your service and you're set to go.

I am using it for an ASP.Net service.

what do u mean " a scriptmanager" ?

The ASP.Net Ajax tools have a <asp:Scriptmanager> tag.
If, however, you're not actually using this webservice for AJAX purposes but to call one website's functionality from another website then I imagine you will have to create a web reference and then probably the same thing applies as with a windows application.
