Useful snippet that allows you to render a MVC View to a string.

RenderViewToString.cs

private string RenderViewToString(string viewName, object model)
{
  // assign the model of the controller from which this method was called to the instance of the passed controller (a new instance, by the way)
  this.ViewData.Model = model;

  // initialize a string builder
  using (StringWriter sw = new StringWriter())
  {
    // find and load the view or partial view, pass it through the controller factory
    ViewEngineResult viewResult = ViewEngines.Engines.FindPartialView(this.ControllerContext, viewName);
    ViewContext viewContext = new ViewContext(this.ControllerContext, viewResult.View, this.ViewData, this.TempData, sw);

    // render it
    viewResult.View.Render(viewContext, sw);

    // return the razorized view/partial-view as a string
    return sw.ToString();
  }
}
