- Click the convert button.
- The resulting C# code from the conversion will be displayed in the output box.
Examples
The following are examples of code conversion from C++ to C# using this converter. Note that you may not always get the same code since it is generated by an AI language model which is not 100% deterministic and gets updated from time to time.
Example 1 - Is String Palindrome
Program that checks if a string is a palindrome or not.
C++
C#
Example 2 - Even or Odd
A well commented function to check if a number if odd or even.

Key differences between C++ and C#
| Characteristic | C++ | C# |
|---|---|---|
| Syntax | C++ uses a syntax that is similar to C, but with additional features such as classes and templates. | C# uses a syntax that is similar to Java, but with additional features such as properties and delegates. |
| Paradigm | C++ supports multiple programming paradigms, including procedural, object-oriented, and generic programming. | C# supports multiple programming paradigms, including object-oriented, component-oriented, and functional programming. |
| Typing | C++ is a statically typed language, which means that the type of a variable is determined at compile time. | C# is a statically typed language, which means that the type of a variable is determined at compile time. |
| Performance | C++ is known for its high performance and is often used for systems programming and game development. | C# is generally slower than C++ but is still considered a high-performance language and is often used for enterprise applications. |
| Libraries and frameworks | C++ has a large number of libraries and frameworks available, but they can be more difficult to use than those in other languages. | C# has a large number of libraries and frameworks available, including the .NET Framework, which provides a wide range of functionality. |
| Community and support | C++ has a large and active community, with many resources available for learning and support. | C# has a large and active community, with many resources available for learning and support. |
| Learning curve | C++ has a steep learning curve, due to its complexity and the need to manage memory manually. | C# has a relatively gentle learning curve, due to its simpler syntax and automatic memory management. |
Frequently Asked Questions
How do I convert C++ to C#?
Paste your C++ code into the input box, confirm the languages are set to C++ and C#, and click Convert. CodeConvert AI analyzes your C++ code and generates equivalent C# code in seconds, preserving the original logic and structure.
What are the main differences between C++ and C#?
C++ and C# 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 C# equivalent. See the comparison table below for the key differences between C++ and C#.
Is the converted C# code accurate?
The AI produces high-quality C# code that preserves the behavior of your original C++ code and follows C# conventions. It handles common patterns, data structures, and idioms for both C++ and C#. For large or performance-critical code, review and test the C# output before using it in production.
Can I convert an entire C++ project to C#?
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 C#. Signing in for free raises the input limit to 25,000 characters per conversion for larger files.
Can I convert C# back to C++?
Yes. CodeConvert AI converts in both directions, so you can convert C# to C++ just as easily using our C# to C++ converter. Try the C# to C++ Converter
Is the C++ to C# 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 C# without an account for up to 5 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.
