C# JArray中JSON.NET多个orderby和Linq

我有下面的JSON，我想知道是否可以使用Linq执行多个

OrderBy

var body = @"[{                            
        ""portOfLoading"": ""GOT"",
        ""bookingResponses"":[{

        ]
    }

            }
            ]
        },{

            }
            ]
        },{
        ""portOfLoading"": ""GOT"",
        ""bookingResponses"":[{
                ""bookingNumber"": ""10"",

                ""description"": ""desc"",
                ""length"": ""7482"",
                ""netWeight"": ""12345"",
                ""plugin"": ""true"",
                ""resourceCode"": ""CONT26"",
                ""route"": ""GOTZEE"",
                ""status"": ""Price missing"",
                ""unitNumber"": ""ABC123"",
                ""width"": ""0""
            }
            ]
        }
    ]";

到目前为止，我已经有了第一批订单，如下所示：

JArray jsonVal = JArray.Parse(body);
JArray sortQuery = new JArray(jsonVal.OrderBy(obj => obj["portOfLoading"]));

在

“portOfLoading”

之后，我想按

“bookingNumber”

订购。我试过使用

ThenBy

等等，但都没有成功。感谢如果

“bookingResponses”

中始终有一个项目，如您的示例所示，请执行以下操作：

JArray jsonVal = JArray.Parse(body);
JArray sortQuery = new JArray(jsonVal.OrderBy(obj => obj["portOfLoading"])
                                     .ThenBy(obj => int.Parse(obj["bookingResponses"].FirstOrDefault()?["bookingNumber"].ToString())));

---

添加

Int.Parse

的原因是，如果没有它，

“bookingNumber”

将按其文本顺序（作为字符串）排序，而不是按数字排序。导致顺序为：1,10,11,3。如果不能确定这些值是否始终是有效整数（从而导致

InvalidCastException

），可以执行类似于中的操作，如果

“bookingResponses”

下面有多个项目呢？您的预期输出是什么？您可以使用

。然后（我想是obj2=>obj2[“bookingNumber”]

。@Achiles您不能，请参阅Gilad的答案以了解为什么这不够。
