Such URL patterns are difficult to achieve using convention-based routing and it will take extra efforts. There are different Types of action results in ASP.NET MVC. Each result has a different type of result format to view page. The ViewDataDictionary class is like a regular key/value collection and is accessed through the ViewData property of the Controller class. It is responsible to display the data received from the controller. This is a template to dynamically generate HTML which transforms the Model into UI.
Name The Adapter Used To Get The Data From An Access Database?
A .Net web service is defined as a software program intended to use XML to exchange information with other software through standard internet protocols. In simple terms, web services provide a path to interact with objects over the internet. To restrict the type of HTTP calls to GET or POST only we require to decorate the MVC action by “HttpGet” or “HttpPost” attribute. Below is the sequence of events that happen every time an HTTP request is handled by our application. Instead of fetching all resources one by one, we create a bundle and fetch that bundle in a single request. This tells MVC to redirect to specified action instead of rendering HTML.
Asax in .Net is an optional file used for handling high-level application events, like Application-start, Application-end, Session-end, Session Start, etc. Asax file is stored in the root directory of the .Net application. MSIL, i.e., Microsoft Intermediate Language, the compiler converts the source code into MSIL during the compilation. It is a set of independent CPU instructions which can be efficiently converted into native code. Boxing is a mechanism of converting a value type to an object type or any interface type. When a CLR boxes a value type, the value inside the system is wrapped.
When convention-based routing is complex to support certain URL patterns. We generally spend more time to write the code for the CRUD operations like connect the database and write create, retrieve, update and delete code. If we do not want a public method to be an action method, we use the “NonActionAttribute” attribute. If redirection occurs then viewdata and ViewBag values become null. The Razor view was introduced with ASP.NET MVC 3 and is the default view engine moving forward.
Actions are the methods in Controller class which is responsible for returning the view or json data. Action will mainly have return type — “ActionResult” and it will be invoked from method — “InvokeAction()” called by controller. Memory-mapped files map the content or data of the file to the logical address of the application. Memory maps enable you to run multiple processes on the same machine by sharing data with each other. The method MemoryMappedFile.CreateFromFiles to obtain a memory-mapped object.
The data elements include strings, integers, characters, or other data types. Garbage collection is the feature of the .Net framework. The GCmanages your application’s release and allocation of memory. Whenever you create a new object, the CLR allocates the memory for the item from the heap.
GAC, i.e., Global Assembly Cache, is a Windows directory folder to store the .Net assemblies and are designated to be shared by all the executing applications on the system. In simple terms, assemblies are shared among multiple applications, on a machine, by registering to GAC. Just In Time compiler, known as JIT, is a part of CLR in .Net, which aids in managing the execution of .Net programs irrespective of the .Net programming language. JIT is responsible for converting MSIL or CIL into machine code. Apart from that, the interviewer checks your communication skills and confidence levels.

ViewResult – Returns a ViewResult which renders the specified or default to the response. ViewModel can have specific validation rules using data annotations. ViewData is similar to ViewBag but is implemented using ViewDataDictionary class rather than a dynamic object. By using the MVC framework we can design pluggable and extensible components which can be replaced or customized easier than Web Forms.
