HTML template is displayed in email body
Question
We have an HTML file saved as string in DB. This html has a template tag "OrderProductsDetails" inside, and we have special method to replace each placeholder, {{var}} or {{%var}}, with its corresponding value.
<!DOCTYPE html>
<html>
<body>
<template id="OrderProductsDetails">
Product: {{%Name}} <br/>
Quantity: {{%Quantity}} <br/>
Amount: {{%TotalCost}}<br/>
</template>
<b> Order details: </b> <br/>
Order Id: {{OrderId}} <br/>
Order time: {{OrderCreatedAt}} <br/>
Order type: {{OrderSide}} <br/>
<b>Products details:</b> <br/>
{{OrderProductsDetails}} <br/>
</body>
</html>
This html file is displayed normally in browser. ie the template tag is not shown.
But the problem happens when try to send this file as email body, using System.Net.Mail.MailMessage:
MailMessage message = new MailMessage(from, to)
{
Body = MyHtmlFileFromDB,
IsBodyHtml = true,
BodyEncoding = System.Text.Encoding.UTF8,
Subject = "Temp email",
SubjectEncoding = System.Text.Encoding.UTF8
};
The email body shows the template content on top of the email like this:
Product: {{%Name}}
Quantity: {{%Quantity}}
Amount: {{%TotalCost}}
Order details:
Order Id: 2850
Order time: 12/25/2022 11:46:15 AM
Order type: Buy
Products details:
Product: prodddd
Quantity: 1
Amount: 40,679.050
How can I make this template tag invisible in the email body?

The email client will just see the entire HTML, unlike browser it will not hide the <template> tag. So, you need to write code that removes this 'template' element before setting the Message object's Body property.
