How to send mail from Gmail without login your Gmail account

In this article I am going to discuss how to send mail from Gmail using Asp.net 3.5 without login your Gmail account.

Write the small line of code as follows:

Sample:

html body> form id="form1" runat="server"> fieldset style="width: 500px; padding: 10px;"> <legend>Sending email from GMaillegend> <div align="left" style="padding: 5px;"> Your Gmail EmailID<br /> <asp:TextBox ID="TextBoxSenderEmailId" runat="server"Width="250px">asp:TextBox><font color=silver>Please enter your GMailId <br />(e.g yourId@gmail.com)font><br /><br /> Friend's EmailId<br /> <asp:TextBox ID="TextBoxReceiverEmailId" runat="server"Width="250px">asp:TextBox><font color=silver>Please enter your friend's emailId<br/>(e.g abc@xyz.com)font><br /> <br /> Subject<br /> <asp:TextBox ID="TextBoxSubject" runat="server"Width="350px">asp:TextBox><br /> <br /> Body<br /> <asp:TextBox ID="TextBoxBody" Width="350px" TextMode="MultiLine" Rows="5"runat="server">asp:TextBox><br /><br /> <asp:Button ID="btnSendEmail" runat="server" OnClick="btnSendEmail_Click"Text="Send" />

</div> </fieldset> </form> </body> </html>

using System;

using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; public partial class SendingMailByGMail : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { }
protected void btnSendEmail_Click(object sender, EventArgs e) { System.Net.Mail.MailMessage MyMailMessage = new System.Net.Mail.MailMessage(TextBoxSenderEmailId.Text, TextBoxReceiverEmailId.Text, TextBoxSubject.Text, ""); MyMailMessage.IsBodyHtml = false; MyMailMessage.Body = TextBoxBody.Text; //provide Authentication Details need to be passed when sending email from gmail System.Net.NetworkCredential mailAuthentication = new System.Net.NetworkCredential(TextBoxSenderEmailId.Text,"password");//Sender password

//Smtp Mail server of Gmail is "smpt.gmail.com" and it uses port no. 587 System.Net.Mail.SmtpClient mailClient = new System.Net.Mail.SmtpClient("smtp.gmail.com", 587);

//Enable SSL

mailClient.EnableSsl = true;
mailClient.UseDefaultCredentials = false;
mailClient.Credentials = mailAuthentication;
mailClient.Send(MyMailMessage);
}
}
