WebPages Helpers

ASP.NET WebPages Helpers provide reusable components that simplify common tasks, such as rendering images, sending emails, and creating forms. Helpers make it easy to include advanced functionality in your web applications.

Key Topics

Using Helpers

Example

@{
    var imageUrl = "https://example.com/image.jpg";
}

<h2>Using Image Helper</h2>
<p>@Html.Raw("Sample Image")</p>

Explanation: This example uses Razor syntax to render an image by dynamically generating an HTML img tag with a source URL.

Displaying Images Dynamically

Example

@{
    var imagePath = Url.Content("~/Content/Images/sample.jpg");
}

<p><img src="@imagePath" alt="Dynamic Image" /></p>

Explanation: This example dynamically generates the image source path using the Url.Content helper to ensure proper resolution for server-relative paths.

Sending Email

Example

@{
    WebMail.SmtpServer = "smtp.example.com";
    WebMail.SmtpPort = 587;
    WebMail.EnableSsl = true;
    WebMail.UserName = "your-email@example.com";
    WebMail.Password = "your-password";
    WebMail.Send(
        to: "recipient@example.com",
        subject: "Test Email",
        body: "This is a sample email from ASP.NET WebPages.",
        isBodyHtml: false
    );
}

<p>Email sent successfully.</p>

Explanation: The WebMail helper is configured with SMTP server details and used to send an email with a specified recipient, subject, and body.
