Not to mention the C# interview questions you’ll be asked are hardly predictable. Boxing and Unboxing highlight that C# has a unified view of the type system, meaning that all value types can be treated as objects. Unboxing – Unboxing extracts the value type from the object or any interface type that has been implemented. For Boxing, implicit code may be used, but for Unboxing explicit code must be used. It consists of different actions like creating the file, writing to the file, reading from the file, etc.
C# is a programming language that’s object-oriented and type-safe. This means that the program will catch errors as you make them, preventing you from wasting time fixing minor problems later on. Unmanaged code is any codebase that was developed without the .NET framework, which means that code execution is not handled by the CLR.
Why do you think we need Automation Testing?
Talk about how you prioritize tasks, break them down into smaller chunks, and delegate when necessary. Show that you understand the importance of communication and collaboration with other teams to ensure that all projects are completed on time. You can also discuss any tools or processes https://wizardsdev.com/en/vacancy/qa-automation-engineer-c/ you use to help manage multiple projects at once. Automation engineers are responsible for developing, testing, and deploying automated systems for a variety of applications. This means working with existing infrastructure, often with limited resources and tight deadlines.
Finally, provide an example of a problem you solved using one or more of these technologies. Automation engineers are responsible for the security, reliability, and accuracy of automated systems. This question is designed to determine if a potential hire understands the importance of keeping automated systems secure, reliable, and accurate.

There are two basic operations that are mostly used in file handling is reading and writing of the file. The file becomes stream when we open the file for writing and reading. A stream is a sequence of bytes that is used for communication.
C# can distinguish the methods with different method signatures. Selenium is a framework and a collection of tools which works in conjunction to provide various forms of automation testing. Selenium WebDriver, Selenium Grid, and Selenium IDE are its main parts. Dan is a software architect and technology professional focusing on applications of blockchain technologies. He has years of experience providing professional consulting services to clients ranging from startups to global corporations.
What are the different components of Selenium?
Generally, multiple catch block is used to handle different types of exceptions means each catch block is used to handle different type of exception. Cucumber is an open-source (BDE) behavior-driven development tool. It is used tool for web-based application automation testing and supports languages like Java, Ruby, Ruby, Scala, Groovy, etc. Cucumber reads executable specifications written in plain text and tests the application under test for those specifications. Automation engineers need to understand how to create reliable, accurate systems that meet the needs of their users.
Finally, emphasize your enthusiasm for learning new technologies and your ability to quickly adapt to new situations. Be prepared to discuss your experience with coding languages, such as Python, Java, C++, etc. Talk about any projects you’ve worked on that required the use of these languages and how you used them. If you don’t have much experience in coding languages, mention any courses or classes you took related to coding languages, as well as any self-learning initiatives you may have taken. Finally, emphasize your ability to learn new languages quickly and adapt to different automation processes. To answer this question, you should first explain your approach to identifying areas where automation can improve efficiency or reduce costs.
What’s the Difference Between Boxing & Unboxing in C#?
In this example, we import the MessageBox function from the user32.dll native library using the DllImport attribute. This enables the managed C# code to call the unmanaged Win32 MessageBox function. The marshaling process will handle the conversion of string values and other necessary data types when calling the unmanaged function.
Static declared variables can be accessed globally without needing to create an instance of the class. Void is a type modifier which states the method and is used to specify the return type of a method in C#. During the development of the .Net Framework, Anders Hejlsberg and his colleagues created C#. An object refers to a class instance that allows you to access the methods pertaining to that class. If a class creates an object in memory, it’ll contain all of the information about the class’s variables, methods, and behavior.
It is best practice to name an interface class with ‘I’ to identify it as an interface visually. File handling can refer to the process of opening, reading, writing, and appending to and from files. The two most common file-handling operations are reading and writing, and in each case, the file’s data is converted into a stream of bytes. Both methods have a similar purpose, namely to release unused resources. However, unlike the .Dispose() method, .Finalize() does not guarantee the garbage collection of any unused and released resources. C# is a type-safe, object-oriented language used to create .Net applications with a component-oriented approach.
- When something goes wrong, they need to be able to identify and address the problem quickly and efficiently.
- Get ready to tackle the most difficult questions yet and prove your prowess in the world of C#.
- It is possible to test software in a randomized fashion, which is referred to as exploratory testing.
- In C#, the System.IO namespace contains multiple classes that are used to conduct different file operations such as creation, deletion, closure, and opening.
- De-serialization is the reverse process of creating an object from a stream of bytes.
The language is proposed to be a simple, modern, general-purpose, object-oriented programming language. Automation engineers are responsible for ensuring that automated systems are compliant with industry regulations and standards. This includes understanding the legal and safety implications of the technology they are using, as well as staying up to date on new regulations and changes to existing regulations. By asking this question, the interviewer is looking to see if you understand the importance of compliance and if you have a process in place to ensure your systems are always up to date. Talk about the user interfaces you’ve developed in the past, such as how they were designed and what technologies you used to build them.
