C# Interview Questions and Answers
C#, sometimes also called as C sharp, is a component-oriented, general-purpose computer programming language that encompasses strong typing, declarative, imperative, and object-oriented disciplines. This information has been asked quite a few times recently in C# interview questions. It is a multi-paradigm language that was initially designed for Common Language Infrastructure (CLI).
C# allows the developers to build reusable components for a huge variety of applications. C# is an evolution or extension of C and C++ languages. However, it has taken much of its features from other programming languages as well, including Delphi and Java. When you analyze the basic syntax of C# and Java and C++, it will look very similar, which is intentional and not a coincidence.
Most Frequently Asked C# Interview Questions
Hiring managers will be impressed if you have this information during C# interview questions. A Thread in C# is a set of guidelines or instructions that are executed, and enable the program to do concurrent processing. The concurrent processing of a program helps the developers handle more than one operation at a given time.
The different states of thread are listed below-
- Unstarted
- Running
- WaitSleepJoin
- Suspended
- Aborted
- Stopped
In C#, there is a special data type called the nullable types. To this data type, the developers can assign a normal range of values as well as null range of values.
In C#, you can sort an array using the Using Array.sort(array) function. This function will sort the elements in the entire one-dimensional Array using IComparable implementation for each element of the given Array.
In C#, Stack is used during the static memory allocation. The variables that are allocated on the stack are stored directly in memory and access to this memory is fast. Heap is used during the dynamic memory allocation. The variables that are allocated on heap have memory allocated during runtime and access to this memory is slow.

Advantages
- Easy to understand
- Object and component-oriented
- Faster and safer
C# has grown very rapidly and is used widely. It is mostly because of its versatile syntax and cross-platform support. Developers who are trained in Java, C+ or C++ will be easily and quickly able to work in C#. We have updated our C# interview questions for freshers. The lambda expressions, nullable value types, direct memory access, delegates, and enumerations are powerful features that simplify the language C++; and on top of it, these add-ons are not available in other languages, such as Java.

Development History
C# was developed by Microsoft around the year 2000 within the .NET initiative. Later, this language got approved by Ecma (ECMA-334) as a standard. Designed by Anders Hejlsberg, the current development of C# is being taken care of by Mads Torgersen.
