解决方法
你可以这样做,但你必须应用以下的东西,因为它是由DefaultViewComponentHelper渲染.
您必须创建此实例并创建您需要IViewComponentSelector和IViewComponentInvokerFactory.
要做到这一点,我做了以下事情.
public class HomeController : Controller
{
Microsoft.AspNet.Mvc.DefaultViewComponentHelper helper = null;
Microsoft.AspNet.Mvc.Razor.RazorView razorView = null;
public HomeController(IViewComponentSelector selector,IViewComponentInvokerFactory factory,IRazorPageFactory razorPageFactory,IRazorPageActivator pageActivator,IViewStartProvider viewStartProvider)
{
helper = new DefaultViewComponentHelper(selector,factory);
razorView = new Microsoft.AspNet.Mvc.Razor.RazorView(razorPageFactory,pageActivator,viewStartProvider);
}
public IActionResult Index()
{
ViewContext context = new ViewContext(ActionContext,razorView,ViewData,null);
helper.Contextualize(context);
string st1 = helper.Invoke("My",null).ToString();
return View();
}
}
这是我的示例View Component.
public class MyViewComponent : ViewComponent
{
public MyViewComponent()
{
}
public IViewComponentResult Invoke()
{
return Content("This is test");
}
}
