This post includes the top 50 C# interview questions and answers for freshers and experienced professionals. This article will assist you in improving your C# knowledge and evaluating your present C# understanding.
C# Arrays : Arrays are used to store multiple values in a single variable, rather than declaring a separate variable for each element. It is a fixed-sized sequential collection of elements of the same type.
The data types of the elements in an array can be int, char, float, string, and so on, and they are stored in a contiguous location.
Comments are used in a program to make a section of code easier to understand. They’re used to make the code more readable and to provide a formal description of the code and how it works. The compiler completely ignores comments, so you may put them wherever in a program and not worry about them breaking it.
In this article, we are going to talk about the use of Generics in C# with multiple examples.
In this post, we’ll look at a simple but difficult interview question in C#: Call By Value vs Call By Reference. This is a question that both fresher and experienced developers are asked in interviews. It’s one of the most frequently asked questions by technical interviewers.
In C#, the key difference between abstraction and encapsulation is that encapsulation wraps data and methods into a single unit called class, whereas abstraction hides implementation details and just shows users the functionality.
In this post, we’ll go over how to use the most common collections in C# such as queue, stack, ArrayList, hashtable, and SortedList, as well as the methods they provide.
In this article, I’ll discuss the differences from a practical standpoint, which should help you in deciding between WCF and Web API.
In this post, we’ll discuss some new C# 10 features that will help you to write cleaner, more expressive, and faster code.
C# 10 is supported by .NET 6 and newer framework versions.
You can download Visual Studio 2022, which comes with the .NET 6 SDK.
The following is a list of some of the new features in C# 10.
C# Array vs List: A List<T> is a generic collection that can resize automatically as elements are added and removed, whereas an array is a fixed-size sequential collection of the same type of elements.
C# Struct vs Class – In C#, Struct and Class are user-defined data types that can contain a variety of data types. The main difference between these two is that class is the reference type, whereas Struct is a value type.
The above diagram illustrates the methods and properties of the List class.
In this post, we’ll go through the different types of access modifiers and how to utilize them in C#.
In C#, access modifiers are keywords that describe how a class, its properties, fields, or methods are accessible in a program. These access modifiers are mainly used to specify the type’s and its members’ scopes, as well as to safeguard data from being accidentally changed by external classes or programs.
