Asp.net code to receive mail

Here is an example of how to receive email using ASP.NET:

Step 1: Create a new ASP.NET Web Application

Create a new ASP.NET Web Application project in Visual Studio. Name it, for example, "EmailReceiver".

Step 2: Install the necessary NuGet packages

In the Solution Explorer, right-click on the project and select "Manage NuGet Packages". Search for and install the following packages:

Step 3: Create a new class to receive email

Create a new class file called EmailReceiver.cs in the App_Code folder. Add the following code:

using System;
using System.Net.Mail;
using System.Net;

public class EmailReceiver
{
    public void ReceiveEmail(string emailSubject, string emailBody)
    {
        // Create a new MailMessage object
        MailMessage mail = new MailMessage();

        // Set the sender and recipient email addresses
        mail.From = new MailAddress("[email protected]");
        mail.To.Add("[email protected]");

        // Set the subject and body of the email
        mail.Subject = emailSubject;
        mail.Body = emailBody;

        // Send the email using an SMTP client
        SmtpClient client = new SmtpClient();
        client.Host = "your_smtp_server";
        client.Port = 587;
        client.Credentials = new NetworkCredential("[email protected]", "your_email_password");
        client.Send(mail);
    }
}

Step 4: Configure the SMTP settings

In the Web.config file, add the following configuration settings:

<configuration>
    <appSettings>
        <add key="smtpServer" value="your_smtp_server" />
        <add key="smtpPort" value="587" />
        <add key="smtpUsername" value="[email protected]" />
        <add key="smtpPassword" value="your_email_password" />
    </appSettings>
</configuration>

Step 5: Create a new ASP.NET page to receive email

Create a new ASP.NET page called EmailReceiver.aspx in the root folder of the project. Add the following code:

<%@ Page Language="C#" %>

<script runat="server">
    protected void Page_Load(object sender, EventArgs e)
    {
        // Create an instance of the EmailReceiver class
        EmailReceiver emailReceiver = new EmailReceiver();

        // Get the email subject and body from the request
        string emailSubject = Request.Form["emailSubject"];
        string emailBody = Request.Form["emailBody"];

        // Call the ReceiveEmail method to receive the email
        emailReceiver.ReceiveEmail(emailSubject, emailBody);
    }
</script>

Step 6: Configure the page to receive email

In the Web.config file, add the following configuration settings:

<configuration>
    <system.web>
        <pages>
            <controls>
                <add tagPrefix="asp" namespace="System.Web.UI" assembly="System.Web.Extensions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
            </controls>
        </pages>
    </system.web>
</configuration>

Step 7: Test the email receiver

Run the application and navigate to the EmailReceiver.aspx page. You should see a form with fields for the email subject and body. Enter some test data and submit the form. The email should be received and processed by the EmailReceiver class.

Note: This is just a basic example to demonstrate how to receive email using ASP.NET. You may need to modify the code to suit your specific requirements, such as handling errors, validating email addresses, and storing the received email in a database.
