Static declared variables can be accessed globally without needing to create an instance of the class. Public declared variables can be accessed from anywhere in the application. What is the difference between static, public, and void? No, you cannot execute multiple catch blocks of the same type. Net framework to generate Microsoft Intermediate Language. What is C#?Ĭ# is an object-oriented programming language compiled by the. Now, let us take a look at the top C# interview questions that you might face! 1. There are various roles such as Software Engineer, Senior Software Developer and Software Programmer that candidates can apply for. On average, a C# developers can expect to make approximately $84,243 annually. C# developers would also be expected to maintain applications that were implemented by previous developers.Īs such, there are a lot of opportunities for C# developers in the job market. Generally, C# developers play a part in the complete development cycle of an application. When required, you can define the methods in subclasses at a later time.Ĭ# developers are usually part of a workgroup made up of various disciplines and employed to build and support server-client applications as well as web-based applications that use programs such as C#, ASP.NET framework and SQL, among others. Interfaces, on the other hand, will let you create classes in the form of structures in which you can just declare the methods and not have to define them. Inheritance can help inherit functions and variables of one or more classes into another. 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. Classes and ObjectsĬlasses and objects are part of OOPS. Also, whenever you need to store data, arrays will help you. If you need a specific operation to be performed multiple times, you can create a simple function and use it as needed. Functions/Methods and Arraysįunctions and methods allow code to be grouped together in order to perform specific functions like adding two numbers. Conditionals such as If/Else conditions can help in giving a flow to your program. This way, you can avoid running the code several times manually. Loops, in particular, help you in creating programs that require repetitive tasks. Once you understand the syntax, your next step would be to learn about branching and looping statements. You will also need to understand all the various data types, type-conversion and comments, among others. You will need to learn and understand how to declare variables. The basic step for learning any language is understanding the syntax. You will need to have some understanding of concepts like encapsulation, polymorphism, abstraction, inheritance, interfaces, etc., as C# is an object-oriented programming language.īasic knowledge of C, C++, or Java so you can understand the syntax of C# better.Ĭ# is one of the most flexible programming languages with a powerful runtime, access to a huge amount of library and platform functionality, and a strong set of abstractions. Prerequisites to Learning C#:īasic knowledge of computers, such as working with command-line, file systems, and installing applications such as compilers, interpreters, etc. Having a deep knowledge of these subjects will enable you learn C# quickly and efficiently, and you will be able to write clear, maintainable code. To become proficient in C#, you need to master a few other core concepts and design principles that are prerequisites to learning C#. Learning Roadmap (Tools and Skills Required)
