如何使用视图引擎在asp.net中获取cshtml页面的html字符串？

public class HomeController : Controller
{
    public ActionResult GetHtmlString()
    {
        // 逻辑处理
        // ...

        // 使用视图引擎获取cshtml页面的HTML字符串
        string htmlString = RenderViewToString("YourViewName", model);

        return Content(htmlString);
    }

    private string RenderViewToString(string viewName, object model)
    {
        ViewData.Model = model;
        using (var sw = new StringWriter())
        {
            var viewResult = ViewEngines.Engines.FindPartialView(ControllerContext, viewName);
            var viewContext = new ViewContext(ControllerContext, viewResult.View, ViewData, TempData, sw);
            viewResult.View.Render(viewContext, sw);
            viewResult.ViewEngine.ReleaseView(ControllerContext, viewResult.View);
            return sw.GetStringBuilder().ToString();
        }
    }
}
