如何從JObject獲取某些特定值

Question

我希望得到的文件，文件編號 ， 文件檔案大小 文件名，ID， 事故-reportedOn了以下JObject的：

注意兩個“ [[ ”在開頭。 我必須先減少JObject嗎？

[
[{
        "FILENAME": {
            "id": "renamedtopdf.docx.pdf",
            "label": "fileName",
            "type": "vertex"
        },
        "FILE": {
            "id": "dc92d48b7e29c528b3eb168446e51736101122a821c9e712320bd6842116719a",
            "label": "file",
            "type": "vertex",
            "properties": {
                "fileSize": [{
                    "id": "f9339436-189a-4503-abc6-e2989be6f138",
                    "value": "164198"
                }],
                "mimeType": [{
                    "id": "0a89dbfa-c204-45c8-8524-3fbd02b04e39",
                    "value": "application/vnd.openxmlformats-officedocument.wordprocessingml.document.main+xml"
                }]
            }
        },
        "INCIDENT": {
            "id": "16ea8c8b-65ee-44b3-afbb-98308b092b4f",
            "label": "incident",
            "type": "vertex",
            "properties": {
                "reportedOn": [{
                    "id": "81485296-a62f-4d17-a03f-4995c3cad937",
                    "value": "2/16/2019 10:33:59 AM"
                }]
            }
        }
    },

我假設你已經從兩個數組中提取了JObject 。 在這種情況下，您可以簡單地使用索引運算符來遍歷json文件，如下所示：

json["FILE"]["id"].Value<string>();
json["FILE"]["properties"]["fileSize"]["value"].Value<string>();
json["FILENAME"]["id"].Value<string>();
json["INCIDENT"]["properties"]["reportedOn"]["Value"].Value<string>();

完整示例：

const string text = @"{
    "FILENAME": {
        "id": "renamedtopdf.docx.pdf",
        "label": "fileName",
        "type": "vertex"
    },
    "FILE": {
        "id": "dc92d48b7e29c528b3eb168446e51736101122a821c9e712320bd6842116719a",
        "label": "file",
        "type": "vertex",
        "properties": {
            "fileSize": [
                {
                    "id": "f9339436-189a-4503-abc6-e2989be6f138",
                    "value": "164198"
                }
            ],
            "mimeType": [
                {
                    "id": "0a89dbfa-c204-45c8-8524-3fbd02b04e39",
                    "value": "application/vnd.openxmlformats-officedocument.wordprocessingml.document.main+xml"
                }
            ]
        }
    },
    "INCIDENT": {
        "id": "16ea8c8b-65ee-44b3-afbb-98308b092b4f",
        "label": "incident",
        "type": "vertex",
        "properties": {
            "reportedOn": [
                {
                    "id": "81485296-a62f-4d17-a03f-4995c3cad937",
                    "value": "2/16/2019 10:33:59 AM"
                }
            ]
        }
    }
}";
var json = JObject.Parse(text);
json["FILE"]["id"].Value<string>();
json["FILE"]["properties"]["fileSize"]["value"].Value<string>();
json["FILENAME"]["id"].Value<string>();
json["INCIDENT"]["properties"]["reportedOn"]["Value"].Value<string>();
