JSON模式到C＃类

Question

I am new to JSON, but I understand C# a bit. I have a JSON schema and I ran across a part that I'm not sure how to put it in the objects class.

"def_subscore": {
    "type": "number",
    "minimum": 0,
    "maximum": 10
},
"def_impact": {
    "type": "object",
    "properties": {
        "baseMetricV3": {
            "type": "object",
            "properties": {
                "cvssV3": {"$ref": "cvss-v3.0.json"},
                "exploitabilityScore": {"$ref": "#/definitions/def_subscore"},
                "impactScore": {"$ref": "#/definitions/def_subscore"}
            }
        }
    }
}

As we can see baseMetricV3 is a class object and defined with it's type and properties. exploitabilityScore is supposed to be a "Subscore" which is defined as a number with min and max limitations.

Can I make a class that acts like a double/integer and also has to pass class-specific validations?

Is the schema just saying exploitabilityScore and impactScore are just double/integers that require validation in my code to make sure the value falls between 0 and 10?

Or is the schema just saying exploitabilityScore and impactScore are just double/integers, by the way the data should never come through with values outside of 0 and 10 (as in the validation was already done on their side and the def_subscore was more of an informative)?

Answer 1

If you schema says prop is of type number you have to define some double/int/float/... numerical type for that property and not a class.

If you only want to check, whether a JSON object complies to the given schema, you can use some json validator library to validate the object against the schema.

Additionally, (or if you for instance parse a JSON string to a self defined class) you can use the RangeAttribute for your class

class SomeClass {
    [Range(1, 10)]
    public int SomeValue {get;set;}
}

For other constraints there may be other Annotations. You can even define them yourself like shown here https://stackoverflow.com/a/7256854/3776927
