I’m using the method:

protected string RenderPartialViewToString(string viewName, object model)
        {
            if (string.IsNullOrEmpty(viewName))
                viewName = ControllerContext.RouteData.GetRequiredString("action");

            ViewData.Model = model;

            using (StringWriter sw = new StringWriter())
            {
                ViewEngineResult viewResult = ViewEngines.Engines.FindPartialView(ControllerContext, viewName);
                ViewContext viewContext = new ViewContext(ControllerContext, viewResult.View, ViewData, TempData, sw);
                viewResult.View.Render(viewContext, sw);

                return sw.GetStringBuilder().ToString();
            }
        }

To turn my view into string, to send by email, however, in the email the view runs out of css, even adding the css in <head>

<link href="~/Content/Site.css" rel="stylesheet" />
<link href="~/Content/bootstrap-custom.css" rel="stylesheet" />
<link href="~/Content/bootstrap.css" rel="stylesheet" />

How do I make css appear in the email ?

CSS files are not loaded in emails, the way to style an email sent with HTML is inline style or, load a style tag (in the same email string) with all classes and then use the classes.

As Gustavo Santos said the CSS files are not loaded in an email, the tag can be used <style> for Hotmail, Yahoo! , and Windows Live Mail, but it’s worth noting that in Gmail it takes the tag and its content.

I usually use a tool to inline CSS, the Premailer:

string html = /*busca o seu html*/;

using(var preMailer = new PreMailer(html))
{
     //Aqui podem ser passados parâmetros, como BaseUri, para montar os <link>'s corretamente
     html = pm.MoveCssInline();
}
