1：
public class HomeController : Controller
{
public ActionResult Index()
{
ViewBag.pclass = this; // 通過ViewBag把this指針傳給視圖，
return View();
}
public string f1(int i)
{
int a=i+100;
return a.ToString();
}
}
在視圖文件就可以像下面一樣調用：
@{ Layout = null;
string s = ViewBag.pclass.f1(5);
}
2：
ASP.NET Core 獲取控制器上的自定義屬性
/// <summary> /// 參考代碼Microsoft.AspNetCore.Mvc.Internal.AuthorizationApplicationModelProvider /// </summary> public class TestApplicationModelProvider : IApplicationModelProvider { public void OnProvidersExecuting(ApplicationModelProviderContext context) { //獲取控制器上指定類型的屬性 var ad = context.Result.Controllers.First().Attributes.OfType<IAuthorizeData>(); } public void OnProvidersExecuted(ApplicationModelProviderContext context) { } public int Order { get; } = -1000 + 10; }
注冊：services.AddTransient<IApplicationModelProvider, TestApplicationModelProvider>();
