C# Online Compiler Guide: How to Choose the Best Compiler to Run C# Online

There are several types of programming languages out there, but the C# language is easily one of the most noteworthy. C# is one of the basic languages used for developing applications and code projects supported by the Windows operating system. The C# language was developed with an advanced code syntax that makes it possible to carry out several small and large-scale tasks. 

There is an ecosystem of features and tools that make implementing this programming language easy, one of which is the C# compiler. With the many online C# compiler options in the market, choosing the right one for your project can be confusing. That’s why you need to understand how to select the best compiler to run C# online to prevent complex code conversions.  

Read on to find out our top picks for online C# compilers and online C# editors.  

What Is C#?

C Sharp or the C# language is a generic, object-oriented, statically typed, high-level programming language used in various applications in the .NET framework, ranging from building a website or a console application to building games, desktop applications, and mobile applications. Professionals can also implement C# in designing AI and machine learning architectures. 

This general-purpose language was developed by Anders Hejlsberg from Microsoft in 2000 as a new approach to development. Each version of C# came with more valuable features. Its recent features include asynchronous streams, pattern matching enhancement, code generator support, Roslyn compiler service, static void imports, and top-level statements, making the C# program easier to read.

What Is an Online C# Compiler?

An online C# compiler is a web-based service that has a variety of applications. This program provides tools and resources for transforming C# programming language into an assembly language. 

Basically, the C# compiler takes in the files of code written in C# source code and processes them using preprocessors and other libraries. Then, it converts these files into an executable file containing machine code, the language understood by the computer. 

You don’t need to understand every aspect of the C# language before compiling your source code to create and launch innovative applications. However, you need to understand the C# language features and cross-platform C# development. You can use code snippets to prevent repeating the same lines of code. You can also use code snippets to determine the piece of code you want to reuse. 

How to Run C# Online: Compilers, Interpreters, Code Editors, and IDE

There are a couple of tasks involved in code compilation. Each of these tasks requires defined tools. To avoid running C# programs with performance issues, you need a compiler, code editor, debugging tool, and other valuable libraries. Some of these tools come as standalone programs or can be integrated into one unified program with distinct solution properties.

Online C# Compiler vs Online C# Interpreter

The difference between C# compilers and C# interpreters is that interpreters were not created for C# programs; compilers were. C# is a compiled-based language built with specific compiling features. C# compilers automatically scan and compile entire lines of code base into machine code, while interpreters analyze and interpret each piece of code into the desired language one at a time. 

The overall runtime for C# compilers is faster than that of interpreters, but it takes a long time to analyze and compile code. The overall execution time for Interpreters is slower than that of compilers, but it takes a shorter time to interpret code levels. Compilers require more memory space than interpreters because they generate object code and machine code.

Online C# Compiler vs Online C# Editor

Code editors are software programs used to write code, carry out code checks, and edit lines of code. C# code editors don’t convert the C# code type as compilers do. They help organize source code by identifying issues to correct in the code pattern. But compilers don’t check for coding errors. They only convert the code to another language. 

Code editors can be standalone programs or part of an IDE to improve the overall application performance. You can use code editors before or after the source code has been compiled. A feature-rich code editor like Visual Studio Code usually comes with code syntax highlighting, error tracking, code fixes, and code completion to optimize the code quality.

Online C# Compiler vs Online C# IDE 

IDE stands for an integrated development environment. It is a software platform that comprises a compiler, code editing tool, debugger, and deployment tools. This software application is broader in scope and memory size than a compiler. A C# IDE performs tasks such as writing, building, compiling, editing, running, debugging, and deploying a C# program.

Modern C# IDEs, in addition to the above features, come with integrated version control systems, .NET core support, .NET framework, code navigation, code checks, code generation, code templates, multiple operating systems support, code analysis tools, code refactorings, code completion, code folding to compress the size of the source file, and plugin support. 

Top 5 Online C# Compilers

Manually converting your C# code to machine code can be time-consuming. That’s why in 1952, Grace Murray Hopper developed the first compiler. Compilers can undergo file operations to complete specific tasks, reducing the number of common errors and overall CPU time.

Compilers have extended their functionalities to include code editing and debugging, with most becoming integrated into IDEs. Below, we’ve included a list of suggestions to get you started compiling your C# framework projects.
