What are the main differences between Crystal and C#?
Crystal 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 Crystal construct to its closest C# equivalent. See the comparison table below for the key differences between Crystal and C#.
Is the converted C# code accurate?
The AI produces high-quality C# code that preserves the behavior of your original Crystal code and follows C# conventions. It handles common patterns, data structures, and idioms for both Crystal and C#. For large or performance-critical code, review and test the C# output before using it in production.
Can I convert an entire Crystal project to C#?
