Bridging C# and TypeScript for Full-Stack Development

This C# to TypeScript converter simplifies data transfer between your backend and frontend by automatically generating TypeScript interfaces from C# classes and records.

Why Convert Between C# and TypeScript?

In full-stack applications using .NET backend and TypeScript frontend, maintaining consistent data structures is crucial but time-consuming. This tool eliminates manual conversion errors by:

• Automating DTO (Data Transfer Object) generation
• Ensuring type consistency across your stack
• Reducing maintenance overhead when models change

Supported C# Features

Our converter handles all essential C# constructs with precise TypeScript equivalents:

Class Types

• Classes
• Interfaces/li>
• Records (both body and inline syntax)(each field must be in separate lines)
• Generics
• Inheritance

Data Type Conversion

• Primitive types:
  • boolean → boolean
  • number (byte, short, int, float, double, decimal)
  • bigint (long, ulong)
  • string (string, char)
• Date/time: DateTime, DateOnly, TimeOnly → Date
• Special types: object, dynamic → any
• void → void

Advanced Features

• Custom class types
• Arrays and collections (List<>, IEnumerable<>, arrays)
• Generic type parameters
• Nullable types (?)

How It Works

1. Paste your C# class or record definition in the left panel
2. Click "Convert" to generate the TypeScript interface
3. Copy the result directly into your TypeScript project

This tool is ideal for Angular, React, or Vue developers working with .NET Web API backends, ensuring your frontend models always match your backend DTOs.
