JSON to C# Class

Tool Introduction

The JSON to C# Class tool is a convenient online code converter designed to help developers quickly convert JSON strings into C# entity classes (data models). You just need to paste valid JSON data into the input box, and the tool will automatically parse the JSON structure and generate the corresponding C# class definition code. This greatly simplifies the creation process of C# data models, saving manual writing time and improving development efficiency.

How to Use

1. Visit this JSON to C# Class online tool page.
2. Paste your prepared JSON string into the "JSON String" input box on the left. Please ensure that the entered JSON data format is valid and complete.
3. The tool will usually automatically, or after you click the convert button, display the C# class code generated based on the JSON structure in the "Converted Class" output box on the right.
4. You can directly copy the generated C# class code for use in your C# projects.

Frequently Asked Questions

• Q: What input formats are supported?
• A: This tool only supports standard JSON format strings as input. Please ensure your input data is valid JSON and conforms to RFC 8259 or ECMA-404 specifications.
• Q: What is the format of the output result?
• A: The output result is class definition code that conforms to C# syntax specifications, including properties (usually in the form of public string Name { get; set; }) and corresponding nested class structures, making it easy for C# developers to use directly.
• Q: Will the generated C# class handle data types?
• A: Yes, the tool will automatically infer and generate corresponding C# data types (such as string, int/long/decimal/double, bool, List<T>, YourClassName, etc.) based on the type of JSON value (e.g., string, number, boolean, array, object).
• Q: What if the input JSON string format is incorrect?
• A: If the JSON string format is invalid, the tool will not be able to parse it correctly and generate C# classes, and may give an error message or generate incomplete/incorrect C# code. It is recommended that you use an online JSON validation tool to verify it first.

Notes

• JSON format validity: Please ensure that the "JSON String" you enter is completely legal and correctly formatted JSON data, otherwise it may lead to conversion failure or the generation of incorrect C# classes. It is recommended to use a JSON validation tool to verify it before pasting.
• Data type inference: The tool will try to intelligently infer the C# data type corresponding to the JSON field. For numeric types, if there are floating-point numbers in JSON, it may default to generating double or decimal; integers will generate int or long. Please review and adjust the generated C# data types according to actual business needs.
• Class and property naming rules: The tool will usually automatically convert JSON key names to the commonly used PascalCase naming convention in C#. For top-level JSON objects, if no name is specified, it may default to generating a class name such as RootObject. For nested objects and arrays, corresponding class names and property names will be generated based on the key names.
• Property visibility: The generated C# properties are usually defaulted to public, with { get; set; } accessors, to facilitate data serialization and deserialization operations in C#.
