如何通过超链接C＃从复杂的json中获取价值

Question

我的JSON是：

{
    "kind": "tm:ltm:pool:poolstats",
    "generation": 198990,
    "selfLink": "https://localhost/mgmt/tm/ltm/pool/~part~pool-1/stats?ver=12.1.2",

                        "description": "The pool is available"

                        "value": 55
                    }
                }
            }
        }
    }
}

我想获取“ serverside.curConns”的“值”键的值。怎么样？

在不了解更多用例的情况下，下面是一个示例，说明如何使用JSON.NET C＃通过其直接路径访问请求的令牌：

可运行的DotNetFiddle：

https://dotnetfiddle.net/yecPbV

为方便起见，以下粘贴了逻辑的内容：

var jsonObject = JObject.Parse(json);
var serverSideConnections = jsonObject.SelectToken("entries['https://localhost/mgmt/tm/ltm/pool/~part~pool-1/~part~pool-1/stats'].nestedStats.entries['serverside.curConns'].value");

Console.WriteLine("Current Connections: " + serverSideConnections.Value<int>());

上方json是json blob的字符串表示形式。
