Language comparison
Key differences between C# and Dart
| Characteristic | C# | Dart |
|---|---|---|
| Syntax | C# has a syntax similar to C++ and Java, with curly braces and semicolons. | Dart has a syntax similar to JavaScript, with curly braces and semicolons. |
| Paradigm | C# supports multiple paradigms including object-oriented, imperative, and functional programming. | Dart supports multiple paradigms including object-oriented and functional programming. |
| Typing | C# is a statically typed language with strong type checking. | Dart is a optionally typed language with both static and dynamic typing. |
| Performance | C# is known for its performance and is often used for high-performance applications. | Dart has good performance, but it may not be as optimized as C# for certain use cases. |
| Libraries and frameworks | C# has a wide range of libraries and frameworks available, including .NET and ASP.NET. | Dart has a growing ecosystem of libraries and frameworks, including Flutter for building cross-platform mobile apps. |
| Community and support | C# has a large and active community with good support from Microsoft. | Dart has a growing community with good support from Google and the Flutter community. |

Common questions
Frequently Asked Questions
How do I convert C# to Dart?
Paste your C# code into the input box, confirm the languages are set to C# and Dart, and click Convert. CodeConvert AI analyzes your C# code and generates equivalent Dart code in seconds, preserving the original logic and structure.
What are the main differences between C# and Dart?
C# and Dart differ in syntax, type system, standard libraries, and common idioms, so copying code line for line usually will not compile. The converter maps each C# construct to its closest Dart equivalent. See the comparison table below for the key differences between C# and Dart.
Is the converted Dart code accurate?
The AI produces high-quality Dart code that preserves the behavior of your original C# code and follows Dart conventions. It handles common patterns, data structures, and idioms for both C# and Dart. For large or performance-critical code, review and test the Dart output before using it in production.
Can I convert an entire C# project to Dart?
You can convert C# files one at a time by pasting each file's code. For a full migration, convert each file and then review how classes, dependencies, and project structure map from C# to Dart. Signing in for free raises the input limit to 25,000 characters per conversion for larger files.
Can I convert Dart back to C#?
Yes. CodeConvert AI converts in both directions, so you can convert Dart to C# just as easily using our Dart to C# converter. Try the Dart to C# Converter
Is the C# to Dart converter free, and do I need to install anything?
Yes, it is free and runs in your browser with nothing to install and no IDE extension required. You can convert C# to Dart without an account for up to 2 conversions per day. Sign in for free for higher limits.
What are the benefits of signing in?
Signing in unlocks CodeConvert AI's Pro converter with more powerful AI models, a built-in chat assistant, code execution, saved conversion history, and personal notes. Every free account includes 5 credits and supports up to 25,000 characters of input per conversion, with no credit card required.
