⚠️ Deprecation Notice
This package is not actively maintained anymore due to lack of time and the amount of existing libraries that do similar things. There are many alternatives you can consider:
Render text using Razor templates
The Essential.Templating.Razor package allows you to render text using Razor templates. The implementation is based on RazorEngine which makes it easy to render templates without using ASP.NET MVC.
Assuming the template is located in Hello.cshtml file under Templates directory. Make sure the template is copied to the output directory.
@inherits Essential.Templating.Razor.Template
Hello, @ViewBag.Name!To render a template to a System.String create an instance of ITemplateEngine and call the Render method.
ITemplateEngine engine = new RazorTemplateEngineBuilder()
.FindTemplatesInDirectory("Templates")
.CacheExpiresIn(TimeSpan.FromSeconds(20))
.UseSharedCache()
.Build();
string template = engine.Render(path: "Hello.cshtml", viewBag: new {Name = "John"});The rendered result should look as follows:
Hello, John!
Render emails using Razor templates
The Essential.Templating.Razor.Email package allows to render System.Net.MailMessage instances from Razor templates. Both HTML and text bodies are supported and can be specified using Razor section syntax.
Assuming that you have a following template in Email.cshtml file under Templates directory.
@inherits Essential.Templating.Razor.Email.EmailTemplate
@using System.Net;
@{
From = new MailAddress("[email protected]");
Subject = "Email Subject";
}
@section Html
{
<html>
<head>
<title>Example</title>
</head>
<body>
<h1>HTML part of the email</h1>
</body>
</html>
}
@section Text
{
Text part of the email.
}To get a System.Net.MailMessage object from this template use the following code:
ITemplateEngine engine = new RazorTemplateEngineBuilder()
.FindTemplatesInDirectory("Templates")
.Build();
MailMessage email = engine.RenderEmail("Email.cshtml");
