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.
من بلوک کلی میزارم دوستان متوجه نوع رفتار متد هستند
