Range Attribute to specify a value inside an array max/min lengths

[jgarciadelanoceda]

Is there an existing issue for this?

• I have searched the existing issues

Describe the bug

In this issue domaindrivendev/Swashbuckle.AspNetCore#3120 I thought at first of the RangeAttribute to specify the array min/maxLength, but I do not know if it's the right solution for this matter. I have tested with this property:

[FromQuery, Length(2, 10), Range(-1, 2)]
public int[] Array { get; set; }

The issue at hand is that if you set the RangeAttribute over an array of integer then the model validation does not allow you to put any value:

{
  "type": "https://tools.ietf.org/html/rfc9110#section-15.5.1",
  "title": "One or more validation errors occurred.",
  "status": 400,
  "errors": {
    "Array": [
      "The field Array must be between -1 and 2."
    ]
  },
  "traceId": "00-2553c36e9a1043817d97dfe2746bbb9b-1404e652aadda666-00"
}

And also the OpenApi spec generated by the package Microsoft.AspNetCore.OpenApi does not put the maximum or minimun over the items and it does it over the schema(It writes):

{
	"name": "Array",
	"in": "query",
	"schema": {
		"maximum": 2,
		"minimum": -1,
		"maxItems": 10,
		"minItems": 2,
		"type": "array",
		"items": {
			"type": "integer",
			"format": "int32"
		}
	}
}

And I think it should write:

{
	"name": "Array",
	"in": "query",
	"schema": {
		"maxItems": 10,
		"minItems": 2,
		"type": "array",
		"items": {
			"type": "integer",
			"format": "int32",
			"maximum": 2,
			"minimum": -1,
		}
	}
}

Expected Behavior

The validation of the Annotation to do not occur and also that the OpenApi spec would be the suggested one
