Using-Statement in RazorEngine (without the HtmlHelper from MVC)

.net, razorengine

Solution

The RazorEngine is designed with deriving your own types for use in the Engine itself.

First create your own Helpers:

public class RazorHtmlHelper
{
    public IEncodedString Partial(string viewName)
    {
        ITemplate template = RazorEngine.Razor.Resolve(viewName);

        ExecuteContext ec = new ExecuteContext();

        RawString result = new RawString(template.Run(ec));

        return result;
    }
}

public class RazorUrlHelper
{
    public string Encode(string url)
    {
        return System.Uri.EscapeUriString(url);
    }
}

Next create your own Template:

public class RazorTemplateBase<T> : TemplateBase<T>
{
    private RazorUrlHelper _urlHelper = new RazorUrlHelper();

    private RazorHtmlHelper _htmlHelper = new RazorHtmlHelper();

    public RazorUrlHelper Url
    {
        get
        {
            return this._urlHelper;
        }
    }

    public RazorHtmlHelper Html
    {
        get
        {
            return this._htmlHelper;
        }
    }
}

Before Parsing set your TemplateServiceConfiguration:

Razor.SetTemplateService(new TemplateService(
  new TemplateServiceConfiguration()
  {
    BaseTemplateType = typeof(RazorTemplateBase<>)
  };
));

result = RazorEngine.Razor.Parse(templateText, model);

Now the RazorEngine has `@Html.Partial()` and `@Url.Encode()` available in views.

Problem

I'm using the RazorEngine without the MVC-Framework. That means I don't have the HtmlHelper for creating templates. That's fine, I don't need any methods from it anyway. But I need to create my own methods like the BeginForm. Now those are done with HtmlHelper.ViewContext.Writer.Write, which I don't have. Is there a "out of the box"-way to do that, or do I have to do some magic here?
