When a project is developed, C# source code is compiled into Intermediate Language . IL is a set of instructions that produces a machine code for execution on the machine processor. The most significant difference between C# and its predecessor, C, is that C# is an object-oriented programming language, whereas C is a procedural programming language.

Only declaration is there in these methods, but not the definition. An object is a class instance that can be used to access class methods. No, you cannot execute multiple catch blocks of the same type. Classes capture all the related data together, while objects can help provide the instances in which to gain access to the information stored inside classes. During the development of the .Net Framework, Anders Hejlsberg and his colleagues created C#. C# is a Microsoft-developed, general-purpose, object-oriented programming language that has been accepted by the ISO and ECMA .

Bonus Tips for C# Interviews

The C# language produces really efficient and readable programmes. Discuss the various methods to pass parameters in a method. The ‘using’ statement can be used in order to obtain a resource for processing before automatically disposing it when execution is completed. Basic knowledge of computers, such as working with command-line, file systems, and installing applications such as compilers, interpreters, etc. This can be useful to ‘reverse engineer’ your code after it executes, thus allowing you to observe and examine important metadata for the different elements within your code.

Thus, try to estimate your usage and understand how that will impact the overall cost of the offering. Whether this will be a problem depends in large part on how data is leveraged. Getting caught by a quota and effectively cut off because of budget limitations will render the service virtually useless. Web Testing Robust solution for end-to-end web automated testing. It is critical to use this alternative only in a test environment and not in production. Create test cases to simulate multiple user paths in a real-world situation.

What is the difference between a throw exception and a throw clause in C#?

The collection of web elements that belongs to the application under test along with their locator values. The only thing is the locators are stored in a centralized location than hard coding them in the test scripts. We can set the timeout for a specific amount of time for all the successive web elements. In this specified time, the web driver searches for all the web elements before throwing the NoSuchElementException.

If it could, then it is not a suitable challenge for your application. Configure each test case in the test tool to be manually triggered, using the test data supplied in step 2. Keep QA Automation Engineer C# job track of any instances when the actual output differs from the intended outcome. In this manner, we can provide input much more quickly and test even before the UI is designed.

When should multithreading be used and when should it be avoided in C#?

As elements are added to a hash table, the capacity is automatically increased as required through reallocation. When a method is declared as a virtual method in a base class and has the same definition in a derived class, there is no need to override it in the derived class. But when a virtual method has a different definition in the base class and the derived class, then there is a need to override it in the derived class.

• It is capable of automating window-based applications and anything else visible on the screen without the need for internal API support.
• Both methods have a similar purpose, namely to release unused resources.
• It is used to implement the peripheral abilities of the class.
• The following program depicts the process of reflection by creating a console-based application.
• It is used when a method’s basic functionality is the same, but sometimes more functionality is needed in the derived class.
• Overall, the Verify statement does not halt the program execution whereas the Assert statement does halt the execution.

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 https://wizardsdev.com/ are reading and writing, and in each case, the file’s data is converted into a stream of bytes. The name static declared variables relates to an unchanging value that is strongly typed , but usually, these are just called static variables.

Summarize the Four Access Modifiers in C#.

A structure helps bring various data types together under a single unit. However, while classes are reference types, structures are value types. In C#, a class is a user-defined blueprint from which objects are created. It brings various types of data together to form a single unit.

Start() method marks the beginning of the thread execution. It is one such OOP methodology where one task can be performed in several different ways. To put it in simple words, it is a property of an object which allows it to take multiple forms. C# is a simple, modern and a general-purpose Object-oriented programming language developed by Microsoft within its .NET framework. In this C# Interview Questions blog, I will introduce you to the most commonly asked Interview Questions in C# and what should be your approach to do the same. Some of the most popular automation testing tools include Selenium, Watir, Ranorex, Appium, UFT, Tosca, and SoapUI.

What happens if the inherited interfaces have conflicting method names?

Without allocating a seperate memory location for the already modified string. XML Serialization- It serializes all the public properties to XML document. Readability being one factor, an XML document can also be manipulated in various ways. Classes under this type reside in System.sml.Serialization. Binary Serialization- It is fast and demands less space, converts any code into its binary format.
