C#JSON Schemagood first issue

描述

There are attributes for min/max and regular expressions, maybe more. I'm not sure they're checked by Json.NET when deserializing, but it would nice to have them in general. Also, the JSON Schema generator of Json.NET will use them to reproduce the constraints in the schema.

研究方向
This issue requests adding DataAnnotation attributes (such as MinLength, MaxLength, RegularExpression) to generated C# classes based on JSON Schema constraints. To implement, examine how quicktype currently generates C# code (likely in src/quicktype core/language/CSharp.ts) and how JSON Schema constraints are processed in the schema processing pipeline. The comment mentions that Json.NET's JSON Schema generator uses these attributes, so it would be beneficial for round tripping. There are no prior discussions or PRs to reference, so the implementation should start by adding support for the most common string constraints and ensuring they are emitted when generating C# code.
