Question

I need my app to send a confirmation email to a user. I have used the following method to render the view as a string:

    public string RenderViewToString<T>(string viewPath, T model)
    {
        using (var writer = new StringWriter())
        {
            var view = new WebFormView(viewPath);
            var vdd = new ViewDataDictionary<T>(model);
            var viewCxt = new ViewContext(ControllerContext, view, vdd, new TempDataDictionary(), writer);
            viewCxt.View.Render(viewCxt, writer);
            return writer.ToString();
        }
    }

which I got from here. It works great, however my images aren’t being included. I’m using:

<img src="<%:Url.Content("~/Resource/confirmation-email/imageName.png") %>"

which is giving me

http://resource/confirmation-email/imageName.png

This works fine when viewing the page on the site, however the image links don’t work in the email.

I need it to give me me:

http://domain.com/application/resource/confirmation-email/imageName.png

I’ve also tried using:

VirtualPathUtility.ToAbsolute()

Answer 1

This is what I used on a site recently:

public static string ResolveServerUrl(string serverUrl, bool forceHttps = false, bool getVirtualPath = true)
{
    if (getVirtualPath)
    serverUrl = VirtualPathUtility.ToAbsolute(serverUrl);

    if (serverUrl.IndexOf("://") > -1)
    return serverUrl;

    string newUrl = serverUrl;
    Uri originalUri = System.Web.HttpContext.Current.Request.Url;
    newUrl = (forceHttps ? "https" : originalUri.Scheme) + "://" + originalUri.Authority + newUrl;
    return newUrl;
}

I could then use it to generate Absolute urls by doing Core.ResolveServerUrl("~/Resource/confirmation-email/imageName.png"); (assuming you wrap the static function in a class named Core)
