C#

Hi,

When i am trying to send a mail through webservice locally it gets send. But when i am using it as a reference in another project. I get this issue :

{[{"Result" : "System.Security.SecurityException : System.Security.Permissions.SecurityPermission
   at EASendMAil.6y.2l(UInt32 6m, Byte[] 6m, Byte[] 6m)
   at EASendMail.4k.2N(string 6m, MailStyle 6m, Int64 6m, Int32 6m)
   at EASendMail.SmtpMail.3D(MailStyle 6m)
   at EASendMail.SmtpMail..ctor(String v)
   at EASendMail.SendMail.sendMail(String ToEmail, String password) at...
 
   The type of the first permission that failed was :
    System.Security.Permissions.SecurityPermission
    The Zone of the assembly that failed was : MyComputer"}]}

What should be done to solve this problem?

The code for SendEmail.cs : (The dll is included in the references)

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using EASendMail;
using System.Net.Mail;

namespace EPWSBL
{
   public class SendEmail
    {
        public void sendMail(String ToEmail, String password)
        {
            SmtpMail oMail = new SmtpMail("TryIt");

            EASendMail.SmtpClient oSmtp = new EASendMail.SmtpClient();

            // Set sender email address, please change it to yours
            oMail.From = "abc@gmail.com"

            // Set recipient email address, please change it to yours
            oMail.To = ToEmail;

            // Set email subject
            oMail.Subject = " Password";

            // Set email body
            oMail.TextBody = " Hi, your user name is : " + ToEmail + " and password is : " + password;

            // Your SMTP server address
            SmtpServer oServer = new SmtpServer("smtp.gmail.com");

            // User and password for ESMTP authentication, if your server doesn't require
            // User authentication, please remove the following codes.            
            oServer.User = "abc@gmail.com";
            oServer.Password = "123456";

            // If your smtp server requires SSL connection, please add this line
            oServer.ConnectType = SmtpConnectType.ConnectSSLAuto;

            try
            {
                Console.WriteLine("Start to send email ...");
                oSmtp.SendMail(oServer, oMail);
                Console.WriteLine("Email was sent successfully!");
            }
            catch (Exception ep)
            {
                Console.WriteLine("Failed to send email with the following error:");
                Console.WriteLine(ep.Message);

            }
            Console.ReadLine();

        }
    }
}

The code in Business Logic is:

public string wsForgotPasswordForCoordinator(string CoordinatorEmailID)
        {
            string emailid = CoordinatorEmailID;
            try
            {
                string password = coordinator.getCoordinatorPassword(emailid).ToString();
                if (password.Equals(null))
                {
                    //return "This EmailID Does Not Exist";
                    return "False";
                }
                else
                {
                    SendEmail send = new SendEmail();
                    send.sendMail(CoordinatorEmailID, password);
                    //return "Password Send Successfully To Your EmailID";
                    return "True";
                }
            }
            catch (Exception e)
            {
                return e.ToString();
                throw;
            }
        }

The webservice class contains :

public string wsChangePasswordForCoordinator(string str)
        {
            String CoordinatorEmailID = string.Empty;
            String OldPassword = string.Empty;
            String NewPassword = string.Empty;

            String[] para = str.Split('{', '}', '[', ']', ':', '"');

            for (int i = 0; i < para.Length; i++)
            {
                if (para[i].Equals("CoordinatorEmailID"))
                    CoordinatorEmailID = para[i + 3];
                else if (para[i].Equals("OldPassword"))
                    OldPassword = para[i + 3];
                else if (para[i].Equals("NewPassword"))
                    NewPassword = para[i + 3];
            }

            EPWSBL.Coordinator CBL = new EPWSBL.Coordinator();
            string result = CBL.wsChangePasswordForCoordinator(CoordinatorEmailID, OldPassword, NewPassword);
            return result;
        }

The webservice contains :

[WebMethod]
        public string wsForgotPasswordForCoordinator(string strCoordinatorData)
        {
            ManageProfile MP = new ManageProfile();

            string result = MP.wsForgotPasswordForCoordinator(strCoordinatorData);

            string JSONresult = "{[{\"Result\":\"" + result + "\"}]}";

            return JSONresult;
        }

This error occur while at this statement:

MessageBox.Show(abc.wsForgotPasswordForCoordinator("{{\"CoordinatorEmailID\":\"abc@gmail.com\"}}"));

The error is :

{[{"Result" : "System.Security.SecurityException : System.Security.Permissions.SecurityPermission
   at EASendMAil.6y.2l(UInt32 6m, Byte[] 6m, Byte[] 6m)
   at EASendMail.4k.2N(string 6m, MailStyle 6m, Int64 6m, Int32 6m)
   at EASendMail.SmtpMail.3D(MailStyle 6m)
   at EASendMail.SmtpMail..ctor(String v)
   at EASendMail.SendMail.sendMail(String ToEmail, String password) at...

   The type of the first permission that failed was :
    System.Security.Permissions.SecurityPermission
    The Zone of the assembly that failed was : MyComputer"}]}

This project is containing the service reference of my webservice.

Thanks in advance............
