Send html view as an email attachment in asp net mvc razor

Introduction

ASP.NET is a popular programming language used for web . One common requirement in web applications is to send an HTML view as an email . In this article, we will explore how to achieve this using ASP.NET MVC .

Step 1: a View

The step is to create a view that represents the HTML content you want to send as an email attachment. This view can be a regular Razor view with HTML markup and dynamic content using Razor syntax.


@model MyModel




    Email Attachment


    

Welcome, @Model.Name!

Here is the content of the email attachment.

Step 2: Render the View as HTML

Next, we need to render the view as HTML so that we can it to the email. We can use the RenderViewToString method to achieve this. This method takes the view name and model as parameters and returns the rendered HTML as a string.


 static string RenderViewToString(ControllerContext context, string viewName, object model)
{
    var  = new ViewDataDictionary(model);
    var tempData = new TempDataDictionary();
    var controller = context.Controller;

    using (var sw = new StringWriter())
    {
        var viewResult = ViewEngines.Engines.FindView(context, viewName, null);
        var viewContext = new ViewContext(context, viewResult.View, viewData, tempData, sw);
        viewResult.View.Render(viewContext, sw);

        return sw.ToString();
    }
}

Step 3: Attach the HTML to the Email

Now that we have the rendered HTML, we can attach it to the email. We can use the Attachment class from the System.Net.Mail namespace to create an attachment object. We then set the content type to “text/html” and provide the HTML content as a stream.


var htmlContent = RenderViewToString(ControllerContext, "EmailView", model);

var attachment = new Attachment(new MemoryStream(.GetBytes(htmlContent)), "email.html", "text/html");

Step 4: Send the Email

Finally, we can send the email with the attached HTML. We can use the SmtpClient class from the System.Net.Mail namespace to send the email. We need to provide the SMTP server details, sender and recipient email addresses, subject, and body of the email.


var smtpClient = new SmtpClient("smtp.example.com");
var mailMessage = new MailMessage("sender@example.com", "recipient@example.com", "Email Attachment", "Please find the attached HTML.");

mailMessage.Attachments.Add(attachment);

smtpClient.Send(mailMessage);

Conclusion

In this article, we have learned how to send an HTML view as an email attachment in ASP.NET MVC Razor. By rendering the view as HTML and attaching it to the email, we can provide rich content to the recipients. This can be useful for newsletters, reports, or any other HTML-based content via email.
