ASP.NET MVC Interview Questions Part - II Day 26

Lecture 26 : ASP.NET MVC Interview Questions Part - II

1) How is the URL structure of MVC core ?

  • URL structure of MVC core is controller name with action name.

  • Example : localhost:1234/{controller}/{action name}. The "localhost:1234" is considered as a controller name.

2) If the view name is different than action name how to invoke it ?

  • If the view name is different from action name we have to write and the view in double quotes.

3) How do we define navigation using anchor tag ?

  • The HTML <a> element (also called the anchor element), containing its href attribute, creates a hyperlink to other web pages, locations within the same page, location to a specified title of another web page, or to an email web page. 

  • The <a> tag defines a hyperlink, which is used to link from one page to another.

  • The navigations can be defined using anchor tag as <a href="/Controller name/Action name"></a>.

4) How to pass model to the view ?

  • The other way of passing an object of the model class to the View. 

  • Erase the code of ViewData and pass the object of model class in return view. 

  • Example : return View("View Name" , Models (Objects) );

5) What is a strongly typed view and how do we create them ?

  • The view which binds to a specific type of ViewModel is called as Strongly Typed View.

  • Strongly Typed View are those views by which we can have intellisence and how to create them you define @model at the top.

  • The Model property then returns the type declared and this type of the Model is now known at the compile time, we get the advantage of IntelliSense and compile time error checking.

Model vs model :

  • It is easy to mix up with the Model and model.

  • The model is directive that is used to declare the type of the ViewModel.

  • The Model is a variable used to access the ViewModel. 

  • The type of Model is declared by the keyword @model.

6) How can we change the startup controller name and action name ?
  • In MVC you can change controller and action location in URL by doing some changes in RouteConfig.cs.
  • For Example : In your application if Home is controller  name and Index is action name  so by default URL created to access it will be :
7) What is routing ?
  • Routing is nothing but user-friendly URL.
  • It is to define URL structure and you map that URL structure with the method name and action name.

Basic Concept In C Sharp Day 16

Lecture 16 : Basic Concept In C Sharp C Sharp : C#  (pronounced  see sharp , like the musical note C♯, but written with the number sign) is a general-purpose, multi-paradigm programming language encompassing static typing, strong typing, lexically scoped, imperative, declarative, functional, generic, object-oriented (class-based), and component-oriented programming disciplines. C# was developed around 2000 by Microsoft as part of its .NET initiative and later approved as an international standard by Ecma (ECMA-334) in 2002 and ISO (ISO/IEC 23270) in 2003. It was designed by Anders Hejlsberg, and its development team is currently led by Mads Torgersen, being one of the programming languages designed for the Common Language Infrastructure (CLI). The most recent version is 9.0, which was released in 2020 in .NET 5.0 and included in Visual Studio 2019 version 16.8. C-sharp musical note : " C sharp " was inspired by the musical notation whereby a sharp symb

Lecture 18 : Understanding C Sharp   Class Library : A class library  defines types and methods that are called by an application. The  Class Library .DLL  contains program code, data, and resources that can be can used by other programs and are easily implemented into other Visual Studio projects. Create New Class Library Project with Visual Studio :  Create New Project : Select C# in the language tab And then select  Class Library (.NET Framework) and press the NEXT button You can then proceed to give your project a Project Name Call the project  MathLibrary  (in order to copy/paste example code) Press the CREATE button, After you have given a name to your project Building the Class Library .DDL for C# : The following code example is a C# version of the Class Library.  The Class Library .DLL contains program code, data, and resources.  The Class Library in this example will feature a custom Math API that has a set of functions to Substract, Devide and Multiply numbers.

Learn Garbage Collection Day 21

Lecture 21 : Learn Garbage Collection Garbage Collection : The garbage collection (GC) manages the allocation and release of memory.  The garbage collector serves as an automatic memory manager.  When there isn’t enough memory to allocate an object, the GC must collect and dispose of garbage memory to make memory available for new allocations. This process is known as  garbage collection . Garbage collection in the following advantages   : It also allocates objects on the managed heap efficient. When objects are no longer used then it will reclaim those objects by clearing their memory, and keeps the memory available for future allocations. Managed objects automatically get clean content to start with, so their constructors do not have to initialize every data field. How GC runs at the Background : Garbage collector runs at the background process . Garbage collector runs at the undetermestic . In background garbage collection (GC), as needed while the collection of progress
