You will have to map the physicalPath to a virtualPath. Here is how you would do that.


public static Configuration OpenConfigFile(string configPath)
{
    var configFile = new FileInfo(configPath);
    var vdm = new VirtualDirectoryMapping(configFile.DirectoryName, true, configFile.Name);
    var wcfm = new WebConfigurationFileMap();
    wcfm.VirtualDirectories.Add("/", vdm);
    return WebConfigurationManager.OpenMappedWebConfiguration(wcfm, "/");
}

let me know.

Hello Friend ,

here is sample to read and specify config settings.

<appSettings>
<add key="customsetting1" value="Some text here"/>
</appSettings>

System.Configuration.Configuration rootWebConfig1 =
  System.Web.Configuration.WebConfigurationManager.OpenWebConfiguration(null);
   if (rootWebConfig1.AppSettings.Settings.Count > 0)
   {
  System.Configuration.KeyValueConfigurationElement customSetting =
   rootWebConfig1.AppSettings.Settings["customsetting1"];
  if (customSetting != null)
   Console.WriteLine("customsetting1 application string = \"{0}\"",
    customSetting.Value);
  else
   Console.WriteLine("No customsetting1 application string");
   }

Step 1 : Add this in Web.config

<system.net>

<smtp>

<network host="smtp.gmail.com"

port="587"

userName=""

password=""

</smtp>

</mailSettings>

</system.net>

Step 2 : Mail Sending Code

using System.Net.Mail;

using System.Net;

protected void btnSent_Click(object sender, EventArgs e)

{

string toEmailAddress = "xx@gmail.com";

string GmailId = "abc@gmail.com";

string bodyMsg = "helo its testing mail";

string subject = "testing mail";

MailMessage mail = new MailMessage();

mail.To.Add(toEmailAddress);

mail.From = new MailAddress(GmailId);

mail.Subject = subject;

mail.Body = bodyMsg;

mail.IsBodyHtml = true;

SmtpClient smtp = new SmtpClient();

smtp.EnableSsl = true;

smtp.Send(mail);

}

hi,

Try for specifiying path

Configuration configuration = WebConfigurationManager.OpenWebConfiguration("~");

smr replied to abinav shankar on 30-Jan-12 08:37 AM

You could use Path.Combine to combine AppDomain.CurrentDomain.BaseDirectory and your relative path.

This will give you a path relative to the ASP.NET root directory (~/) in an ASP.NET app, or a path relative to the directory containing the executable in a WinForms or Console application.
