- The resulting C# code from the conversion will be displayed in the output box.
Examples
The following are examples of code conversion from Objective-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.
Objective-C
C#
Example 2 - Even or Odd
A well commented function to check if a number if odd or even.

Key differences between Objective-C and C#
| Characteristic | Objective-C | C# |
|---|---|---|
| Syntax | Objective-C uses a syntax similar to C with added features for object-oriented programming. | C# has a syntax similar to C and C++ with additional features for object-oriented programming. |
| Paradigm | Objective-C supports both procedural and object-oriented programming paradigms. | C# supports multiple paradigms including object-oriented, procedural, and functional programming. |
| Typing | Objective-C is a dynamically typed language. | C# is a statically typed language. |
| Performance | Objective-C is known for its performance and is often used for developing high-performance applications. | C# provides good performance and is optimized for common programming scenarios. |
| Libraries and frameworks | Objective-C has a rich set of libraries and frameworks, especially for iOS and macOS development. | C# has a wide range of libraries and frameworks available for various development purposes. |
| Community and support | Objective-C has a dedicated community and good support, particularly for iOS and macOS development. | C# has a large and active community with extensive support from Microsoft and the developer community. |
| Learning curve | Objective-C has a moderate learning curve, especially for developers familiar with C and object-oriented programming. | C# has a relatively easy learning curve, especially for developers familiar with C-like syntax and object-oriented programming. |
Frequently Asked Questions
How do I convert Objective-C to C#?
Paste your Objective-C code into the input box, confirm the languages are set to Objective-C and C#, and click Convert. CodeConvert AI analyzes your Objective-C code and generates equivalent C# code in seconds, preserving the original logic and structure.
What are the main differences between Objective-C and C#?
Objective-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 Objective-C construct to its closest C# equivalent. See the comparison table below for the key differences between Objective-C and C#.
Is the converted C# code accurate?
The AI produces high-quality C# code that preserves the behavior of your original Objective-C code and follows C# conventions. It handles common patterns, data structures, and idioms for both Objective-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 Objective-C project to C#?
You can convert Objective-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 Objective-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 Objective-C?
Yes. CodeConvert AI converts in both directions, so you can convert C# to Objective-C just as easily using our C# to Objective-C converter. Try the C# to Objective-C Converter
Is the Objective-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 Objective-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.
