Hi,

I dont have the code in one file. I am using several files. I tried to list
the required code.
I hope this helps. Let me know if you have any questions.

1) In InfoPath form go to Tools--> data connections --> click add -->
    select submit --> select to a web service --> provide the url of the .net
web service and then select the name of the function in the webservice
which wil accept the string data.

2)Below I have listed the function in the web service which will accept the
infopath data.

[WebMethod]
public string GetXmlData(string xmlData)
{
        string url = string .empty;
        // Converts the string data to TextReader object
        TextReader textReaderObj =  new StringReader(xmlData);
        DataSet dsAppXmlData = new DataSet();
        // Reads the xml data in dataset
        dsAppXmlData.ReadXml(textReaderObj);

        foreach(DataRow drRowAppXmlData in dsAppXmlData.Tables[0].Rows)
        {
        // Initially I saved the infopath form to the form library in
sharepoint.There I checked the default url              that sharepoint provided to
open the form. In my case the url was         http://servername/sitename/form
library name/ + lastname + firstname + ".xml";

        The firstname and lastname are the fields on the infopath form. Based on
the above url I constructed the         url dynamically as shown below.
       
       
        // here you need to replace the servername, sitename, form libraray name
url = http://servername/sitename/form libraray name +
            drRowAppXmlData["LastName"].ToString().Trim() +                     drRowAppXmlData
["FirstNametName"].ToString().Trim() +".xml";
       
        }

        return url;
}

3) Once you have the url craete a separate function to send the email

// In the code below you need to assign your own values for strFrom,
subject which will contain the url etc.

code to send the mail

using System.Web.Mail;

// sends an email using the .Net MailMessage class
MailMessage mail = new MailMessage();
mail.From = strFrom;
mail.Subject = subject;
mail.Priority = MailPriority.Normal;

mail.BodyFormat = MailFormat.Text;
mail.Body = body;
mail.To = strTo;
mail.Cc = strCC;
SmtpMail.SmtpServer = SMTP Server;
SmtpMail.Send(mail);
