如何创建嵌套的 json？

Question

请帮忙。我正在尝试使用 Newtonsoft 对以下内容进行序列化，但无法使其正常工作。生成的 JSON 应该类似于 Postman 的提取。我只是不知道如何在运行序列化之前构建数据的添加 谁能指出我正确的方向？

必需的 JSON 输出

{
"Line": [
    {
        "Id": "1",
        "LineNum": 1,
        "Description": "Test Sales Description",
        "Amount": 100,
        "DetailType": "SalesItemLineDetail",
        "SalesItemLineDetail": {
            "ItemRef": {
                "value": "3",
                "name": "Test:Test Item"
            },
            "UnitPrice": 100,
            "Qty": 1,
            "ItemAccountRef": {
                "value": "6",
                "name": "Sales"
            },
            "TaxCodeRef": {
                "value": "6"
            }
        }
    },
    {
        "Amountlin": 0,
        "DetailType": "SubTotalLineDetail",
        "SubTotalLineDetail": {}
    }
],
"TxnTaxDetail": {
    "TotalTax": 0,
    "TaxLine": [
        {
            "Amount": 0,
            "DetailType": "TaxLineDetail",
            "TaxLineDetail": {
                "TaxRateRef": {
                    "value": "7"
                },
                "PercentBased": true,
                "TaxPercent": 20,
                "NetAmountTaxable": 0
            }
        }
    ]
},
"CustomerRef": {
    "value": "2",
    "name": "Test Company"
},
"BillAddr": {
    "Id": "3",
    "Line1": "21 TEST TEST",
    "Line2": "TEST",
    "City": "TEST",
    "Country": "United Kingdom",
    "PostalCode": "POSTCODE"
},
"ShipAddr": {
    "Id": "3",
    "Line1": "21 TEST TEST",
    "Line2": "TEST",
    "City": "TEST",
    "Country": "United Kingdom",
    "PostalCode": "POSTCODE"
}

}

我创建了以下对象

 public class ItemRef
    {
        public string value { get; set; }
        public string name { get; set; }
    }

    public class ItemAccountRef

    }

        public int NetAmountTaxable { get; set; }
    }

    public class TaxLine
    {
        public int Amount { get; set; }
        public string DetailType { get; set; }

    }

        public List<TaxLine> TaxLine { get; set; }
    }

    public class CustomerRef
    {
        public string value { get; set; }
        public string name { get; set; }
    }

    public class BillAddr
    {
        public string Id { get; set; }
        public string Line1 { get; set; }
        public string Line2 { get; set; }
        public string City { get; set; }
        public string Country { get; set; }
        public string PostalCode { get; set; }
    }

    public class ShipAddr
    {
        public string Id { get; set; }
        public string Line1 { get; set; }
        public string Line2 { get; set; }
        public string City { get; set; }
        public string Country { get; set; }
        public string PostalCode { get; set; }
    }

    public class Root
    {
        public List<Line> Line { get; set; }
        public TxnTaxDetail TxnTaxDetail { get; set; }
        public CustomerRef CustomerRef { get; set; }
        public BillAddr BillAddr { get; set; }
        public ShipAddr ShipAddr { get; set; }
    }

您需要设置对象的属性：

ItemRef itemRef = new ItemRef();
itemRef.value = "1";

SalesItemLineDetail salesItemLineDetail = new SalesItemLineDetail();
salesItemLineDetail.ItemRef = itemRef;

Line line = new Line();
line.Id = "1";
line.LineNum = 1;
line.SalesItemLineDetail = salesItemLineDetail;

Root root = new Root();
root.Line = new List<Line>();
root.Line.Add(line);

string body = JsonConvert.SerializeObject(root);
