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
- Visit this JSON to C# Class online tool page.
- 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.
- 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.
- 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#.
