Discuss What Garbage Collection Is And How It Works Provide A Code Example Of How You Can Enforce Garbage Collection In Net

C# Interview Questions

Garbage collection is a low-priority process that serves as an automatic memory manager which manages the allocation and release of memory for the applications. Each time a new object is created, the common language runtime allocates memory for that object from the managed Heap. As long as free memory space is available in the managed Heap, the runtime continues to allocate space for new objects. However, memory is not infinite, and once an application fills the Heap memory space, garbage collection comes into play to free some memory. When the garbage collector performs a collection, it checks for objects in the managed Heap that are no longer being used by the application and performs the necessary operations to reclaim the memory. Garbage collection will stop all running threads, it will find all objects in the Heap that are not being accessed by the main program and delete them. It will then reorganize all the objects left in the Heap to make space and adjust all the Pointers to these objects in both the Stack and the Heap.

To enforce garbage collection in your code manually, you can run the following command :

System.GC.Collect 

To summarize:

  • When compiled, source code is first translated to IL .
  • CIL is then assembled into a bytecode and a CLI assembly is created.
  • Before code execution, CLI code is passed through the runtimeâs JIT compiler to generate native machine code.
  • The computerâs processor executes the native machine code.

    Senior Developers Vs Junior Developers

    There are several factors that set junior and senior developers apart. Most senior developers have a much wider range of extensive duties in addition to their normal software development work. In particular, they are likely to be responsible for leading a team of developers, or for managing a number of teams of developers.

    At one end of the leading/managing spectrum, the form of leadership may be more in the style of a Scrum Master. At the other end of the spectrum, the senior developer might be working on organizational issues or perhaps focusing on activities related to keeping the business profitable. A good senior developer will be able to handle all kinds of challenges that would severely test the abilities of junior or mid level developers.

    Mr. Mark Richman: I happened to whiteness your interview that day. An interview with the CIO is not about your technical skills, but rather about your style of engagement with team members and your ability to add discussion value versus desperately trying to make a stand on your opinions. In my view, bad move on your part not understanding the actual purpose of the drag and drop question. It was not a technical question, and your ego might have gotten the better of a well crafted interview designed to find the brightest talent in the marketplace.Less

    What Is Multithreading

    Multithreading is a process that uses multiple threads, each of which performs unique activities. In this way, one process can perform several types of activities at the same time. You can see the number of threads a single process is running in the Task Manager on your PC.

    Following are the ways in which .NET supports multithreading:

  • Using ThreadPool class with asynchronous methods.
  • Starting threads with ThreadStart delegates.
  • What Is An Assembly

    An assembly is a file that is automatically generated by the compiler which consists of a collection of types and resources that are built to work together and form a logical unit of functionality. We can also say, assembly is a compiled code and logical unit of code.

    Assemblies are implemented in the form of executable or dynamic link library files.

    What Is State Management In Net

    State management allows servers to store data to monitor or maintain the state of objects during runtime. The best example is when a user shops online. A typical purchase cycle includes adding items to the cart, checkout, information form filling, and order placement.

    A user clicks a link after each step, which would typically wipe out the information they entered previously. However, state management features like cookies, control state, query strings, etc., allow pages to retain the information.

    There are two key types of state management:

  • Client-Based State Management
  • Server-Side State Management
  • Client-Based State Management Client-based state management involves retaining information on the page or storing it on their system. Therefore, the scenario mentioned above is an example of this type of state management.

    Server-Side State Management Server-side state management stores information on the server rather than presenting it in front of the client. This type of state management is ideal for cases when the operator wants to optimize information shared with the client to prevent cluttering.

    Application state, session state, and profile properties are the core features of server-side state management.

    Although this section is relatively basic, it can be one of the senior .NET developer interview questions you come across.

    What Is The Meaning Of State Management In Net

    State management, as the name suggests, is used to constantly monitor and maintain the state of objects in the runtime. A web page or a controller is considered to be an object.

    There are two types of state management:

    • Client-side: It is used to store information on the clients machine and is formed mostly of reusable and simple objects.
    • Server-side: It stores the information on the server and makes it easier to manage and preserve the information on the server.

    Next up on this top .net interview questions for freshers and experienced, let us understand the difference between an object and a class.

    What Are Three Common Acronyms Used In Net And What Do They Stand For

    This one should be easy for .NET developer candidates to answer. The question allows them some flexibility in choosing terms with which they are most familiar. Three frequently used acronyms in .NET are IL, CIL and CLI:

    • IL stands for Intermediate Language, which is an object-oriented programming language that is a partially compiled code that .NET developers will then compile to native machine code.
    • CIL stands for Common Intermediate Language, formerly known as Microsoft Intermediate Language . This is another programming language that .NET developers use, and it represents the lowest possible level for a language that humans can still read.
    • CLI stands for Common Language Infrastructure. This is a compiled code library that Microsoft developed as an open specification. Developers use CLI for security, versioning and deployment purposes.

    Other acronyms commonly used in .NET include JIT compiler, which uses the target machines CPU architecture to perform a .NET operation OOP , defined in Question 1 CLR , defined in Question 11 and LINQ , defined in Question 12.

    Write A Program To Calculate The Addition Of Two Numbers

    The steps are as follows:

    1. You need to create a new ASP.NET Core Project CalculateSum. Open Visual Studio 2015, goto File> New> Project. Select the option Web in Left Pane and go for the option ASP.NET Core Web Application under the central pane. Edit the project name as CalculateSum and click on OK.

    2. In the template window, select Web Application and set the Authentication into No Authentication and click on OK.

    3. Open Solution Explorer and right-click on the folder Home , then click on Add New Item. You need to select MVC View Page Template under ASP.NET Section and rename it as addition.cshtml and then click on the Add button.

    4. Open addition.cshtml and write the following code:

     @< h1> Welcome to Addition Page< /h1> < form asp-controller="Home" asp-action="add" method="post"> < span> Enter First Number : < /span> < input id="Text1" type="text" name="txtFirstNum" /> < br /> < br /> < span> Enter Second Number : < /span> < input id="Text2" type="text" name="txtSecondNum" /> < br /> < br /> < input id="Submit1" type="submit" value="Add" /> < /form> < h2> @ViewBag.Result< /h2> 

    Here, we have created a simple form that is having two text boxes and a single Add Button. The text boxes are named as txtFirstNum and txtSecondNum. On the controller page, we can access these textboxes using:< form asp-controller=”Home” asp-action=”add” method=”post”>

    This form will indicate all the submissions will be moved to HomeController and the method add action will be executed.
