使用空属性名称

Question

如果我有下面的json对象...我怎么能访问字符串“密码必须...”。

ModelState中的“”属性名称让我感到困惑。

谢谢！

{
    "Message": "The request is invalid.",
    "ModelState": {
        "": [
            "Passwords must have at least one non letter or digit character. Passwords must have at least one uppercase ('A'-'Z')."
        ]
    }
}
