Approach 1: the ViewRenderer class

The ViewRenderer class is a utility class that provides a simple way to render a Razor view to a string. It is available as a package and can be easily installed in your project. Here's an example of how to use it:


using ViewRenderer;

public string RenderViewToString(string viewName, object model)
{
    var renderer = new ViewRenderer();

using System.IO;
using System.Web.Mvc;

public string RenderViewToString(string viewName, object model)
{
    var controller = new Controller();
    var view = ViewEngines.Engines.FindView(controller.ControllerContext, viewName, null).View;
    var writer = new StringWriter();
    var viewContext = new ViewContext(controller.ControllerContext, view, new ViewDataDictionary(model), new TempDataDictionary(), writer);
    view.Render(viewContext, writer);
    return writer.ToString();
}

In this approach, we create an instance of the Controller class and use the FindView method of the ViewEngines class to locate the view. We then create a ViewContext object and pass it to the Render method of the view. The rendered view is then written to a StringWriter and returned as a string.
