Common questions
Frequently Asked Questions
How do I convert C# to TypeScript?
Paste your C# code into the input box, confirm the languages are set to C# and TypeScript, and click Convert. CodeConvert AI analyzes your C# code and generates equivalent TypeScript code in seconds, preserving the original logic and structure.
What are the main differences between C# and TypeScript?
C# and TypeScript 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 TypeScript equivalent. See the comparison table below for the key differences between C# and TypeScript.
Is the converted TypeScript code accurate?
The AI produces high-quality TypeScript code that preserves the behavior of your original C# code and follows TypeScript conventions. It handles common patterns, data structures, and idioms for both C# and TypeScript. For large or performance-critical code, review and test the TypeScript output before using it in production.
Can I convert an entire C# project to TypeScript?
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 TypeScript. Signing in for free raises the input limit to 25,000 characters per conversion for larger files.
Can I convert TypeScript back to C#?
Yes. CodeConvert AI converts in both directions, so you can convert TypeScript to C# just as easily using our TypeScript to C# converter. Try the TypeScript to C# Converter
