روش شماره 1 : استفاده از  _ViewStart موجود در ریشه‌ی پوشه Views

با استفاده از کد زیر می‌توانیم فایل پیش فرضی را که قرار است رندر شود، تغییر دهیم:

@{
 var controller = HttpContext.Current.Request.RequestContext.RouteData.Values["Controller"].ToString();
 
 string layout = "";
 if (controller == "Admin")
 {
 layout = "~/Views/Shared/_AdminLayout.cshtml";
 }
 else
 {
 layout = "~/Views/Shared/_Layout.cshtml";
 }
 
 Layout = layout;
}

روش شماره 2 : مشخص کردن لایه در Action

همچنین می‌توانیم فایل مورد نظر را در اکشن خودمان، بازنویسی (override) کنیم:

public ActionResult Index()
{
 RegisterModel model = new RegisterModel();
 //TO DO:
 return View("Index", "_AdminLayout", model);
}

روش شماره 3 : مشخص کردن لایه به ازای هر View

می‌توانیم در هر View هم لایه مربوط به آن را مشخص کنیم:

@{
 Layout = "~/Views/Shared/_AdminLayout.cshtml";
}

روش شماره 4 : اضافه کردن فایل _ViewStart به ازای هر کنترلر

همانطور که در تصویر زیر می‌بینید آخرین روش این هست که می‌توانید فایل‌های _ViewStart مختلفی را به ازای هر کنترلر، داخل پوشه View مربوطه قرار بدید تا سیستم از آن استفاده کند.
