WCF JSON 误解

Question

我正在使用改装从我的 Android phone 向服务器发送请求。结果是 200 OK，但我遇到了下一个问题：我不理解 JSON 响应主体中的 1 种类型的 1 元素。

{
    "Articles":[{
        "Categories":[{
            "Identifier":2147483647,
            "Name":"String content"
        }],
        "Contents":[{
            "URL":"String content"
        }],
        "Country":{
            "Identifier":2147483647,
            "Name":"String content"
        },
        "Description":"String content",
        "ExpiryDate":"\/Date(928146000000+0100)\/",
        "ExtraFields":[{
            "Name":"String content",
            "Value":{
                "Identifier":2147483647,
                "Type":"String content",
                "Value":"String content"
            }
        }],
        "Identifier":2147483647,

            "Categories":[{
                "Identifier":2147483647,
                "Name":"String content"
            }],
            "Contents":[{
                "URL":"String content"
            }],
            "Country":{
                "Identifier":2147483647,
                "Name":"String content"
            },
            "Description":"String content",
            "ExpiryDate":"\/Date(928146000000+0100)\/",
            "ExtraFields":[{
                "Name":"String content",
                "Value":{
                    "Identifier":2147483647,
                    "Type":"String content",
                    "Value":"String content"
                }
            }],
            "Identifier":2147483647,
            "ImageURL":"String content",
            "Name":"String content",
            "Newsbite":true,
            "PortalID":2147483647,
            "PublishDate":"\/Date(928146000000+0100)\/",
            "Region":{
                "Identifier":2147483647,
                "Name":"String content"
            },
            "Related":[null],
            "ShareURL":"String content",
            "Tags":[{
                "Identifier":2147483647,
                "Name":"String content"
            }],
            "Type":2147483647
        }],
        "ShareURL":"String content",
        "Tags":[{
            "Identifier":2147483647,
            "Name":"String content"
        }],
        "Type":2147483647
    }],
    "PageSpecification":{
        "Skipped":2147483647,
        "Taken":2147483647,
        "Total":2147483647
    }
}

1st "Related" 一开始我明白了，但是在 Region 之后的 2nd 我不知道它是什么类型。任何想法这 "Related":[null] 是什么意思以及如何在 JSON?

中声明它

Answer 1

[]表示内容是List。

[null] 表示这是一个包含 null 值的 List
