Free Fortran to C# Converter
How to use this tool?
This free online converter lets you convert code from Fortran to C# in a click of a button. To use this converter, take the following steps -
- Type or paste your Fortran code in the input box.
- 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 Fortran 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.
Fortran
C#
Example 2 - Even or Odd
A well commented function to check if a number if odd or even.
Fortran
C#
Key differences between Fortran and C#
| Characteristic | Fortran | C# |
|---|---|---|
| Syntax | Fortran has a simpler syntax compared to C#. | C# has a more complex syntax compared to Fortran. |
| Paradigm | Fortran is primarily a procedural programming language, but it also supports object-oriented programming. | C# is a multi-paradigm language that supports object-oriented, imperative, and functional programming. |
| Typing | Fortran is a statically typed language. | C# is a statically typed language. |
| Performance | Fortran is known for its high performance and is often used in scientific computing and numerical analysis. | C# is generally slower than Fortran, but it is still a high-performance language. |
| Libraries and frameworks | Fortran has a limited number of libraries and frameworks compared to C#. | C# has a large number of libraries and frameworks available, making it easier to develop applications. |
| Community and support | Fortran has a smaller community compared to C#. | C# has a large and active community with plenty of resources and support available. |
| Learning curve | Fortran has a steeper learning curve compared to C#. | C# has a relatively easy learning curve, especially for developers with experience in other C-style languages. |
Frequently Asked Questions
How do I convert Fortran to C#?
Paste your Fortran code into the input box, confirm the languages are set to Fortran and C#, and click Convert. CodeConvert AI analyzes your Fortran code and generates equivalent C# code in seconds, preserving the original logic and structure.
What are the main differences between Fortran and C#?
Fortran 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 Fortran construct to its closest C# equivalent. See the comparison table below for the key differences between Fortran and C#.
Is the converted C# code accurate?
The AI produces high-quality C# code that preserves the behavior of your original Fortran code and follows C# conventions. It handles common patterns, data structures, and idioms for both Fortran and C#. For large or performance-critical code, review and test the C# output before using it in production.
Can I convert an entire Fortran project to C#?
You can convert Fortran 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 Fortran 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 Fortran?
Yes. CodeConvert AI converts in both directions, so you can convert C# to Fortran just as easily using our C# to Fortran converter. Try the C# to Fortran Converter
Is the Fortran 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 Fortran 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.
