با سلام
در این سناریو هدف خروجی بر اساس html است.
مثلا ما در وب سایت چند جدول داریم که برای خودشون یک PartialView هستند و قصد نداریم که باز طراحی دوباره ای انجام بشود.
در این مثال از یک کلاس ViewRenderService کمک گرفتیم برای کشیدن خروجی html از کنترلر ها
public class ViewRenderService{

    private readonly ICompositeViewEngine _viewEngine;

    private readonly ITempDataProvider _tempDataProvider;

    private readonly IServiceProvider _serviceProvider;

    private readonly IWebHostEnvironment _env;





    public ViewRenderService(

        ICompositeViewEngine viewEngine,

        ITempDataProvider tempDataProvider,

        IServiceProvider serviceProvider,

        IWebHostEnvironment env)

    {

        _viewEngine = viewEngine;

        _tempDataProvider = tempDataProvider;

        _serviceProvider = serviceProvider;

        _env = env;

    }





    public async Task<string> RenderFromPathAsync(ControllerContext context, string absoluteViewPath, object model)

    {

        var actionContext = context as ActionContext;





        using (var sw = new StringWriter())

        {

            string relativeViewPath = absoluteViewPath.Replace(_env.ContentRootPath, "").Replace("", "/").TrimStart('/');





            var viewResult = _viewEngine.GetView(null, relativeViewPath, false);





            if (!viewResult.Success)

            {

                throw new ArgumentException($"View '{relativeViewPath}' not found.");

            }





            var viewData = new ViewDataDictionary(new EmptyModelMetadataProvider(), new ModelStateDictionary())

            {

                Model = model

            };





            var tempData = new TempDataDictionary(actionContext.HttpContext, _tempDataProvider);





            var viewContext = new ViewContext(

                actionContext,

                viewResult.View,

                viewData,

                tempData,

                sw,

                new HtmlHelperOptions()

            );





            await viewResult.View.RenderAsync(viewContext);

            return sw.ToString();

        }

    }

}


و ریجستر شدن
builder.Services.AddScoped<ViewRenderService>();

و برای تبدیل راحت با Aspose.Words فایل نهایی اماده میشود که میتوان هم خروجی word تولید کرد و هم pdf در نهایت در تابع پرینت استفاده شدن.
