使用C#和RestSharp设置正确的嵌套字典

Question

我需要一个比我更聪明的人来指导我在C#中创建一些嵌套字典。我正在尝试在restsharp中创建一个最终类似于这个示例json的帖子：

{
    "brandId": 34344,
    "collectionId": 5,
    "productTypeId": 1,
    "identity": {
        "sku": "SKU0001",
        "ean": "12323423",
        "upc": "543534563",
        "isbn": "54353453",
        "barcode": "45453"
    },
    "stock": {
        "stockTracked": true,
        "weight": {
            "magnitude": 4324.54
        }
    },
    "financialDetails": {
        "taxable": false,
        "taxCode": {
            "id": 7,
            "code": "T20"
        }
    },
    "salesChannels": [
        {
            "salesChannelName": "Brightpearl",
            "productName": "Product B",
            "productCondition": "new",
            "categories": [
                {
                    "categoryCode": "276"
                },
                {
                    "categoryCode": "295"
                }
            ],
            "description": {
                "languageCode": "en",
                "text": "Some description",
                "format": "HTML_FRAGMENT"
            },
            "shortDescription": {
                "languageCode": "en",
                "text": "Some description",
                "format": "HTML_FRAGMENT"
            }
        }
    ],
    "seasonIds": [
        1,
        2,
        3
    ],
    "nominalCodeStock": "1000",
    "nominalCodePurchases": "5000",
    "nominalCodeSales": "4000",
    "reporting": {
        "seasonId": 3,
        "categoryId": 295,
        "subcategoryId": 298
    }
}

我以前没有尝试过创建嵌套字典。我的经验更多地局限于：

Dictionary<string, string> values = new Dictionary<string, string>
{
    { "brandid", "1234" },
    { "productTypeId", "11" }
};

string json = JsonConvert.SerializeObject(values);


List<Dictionary<string, string>> ld = new List<Dictionary<string, string>>
{
    values
};

request2.AddJsonBody(ld);

如果能帮我指明正确的方向，我将不胜感激。

Answer 1

我建议您创建对象。如下所示：

public class Portfolio {
    public int brandId;
    public int collectionId;
    public int productTypeId;
    public Identity identity
    // etc
}

public class Identity {
   public string sku;
   // etc
}

然后创建一个新的portfolio对象，序列化它并通过网络发送它。

var portfolio = new Portfolio
{
    // initialize values here
};

string json = JsonConvert.SerializeObject(portfolio);

Answer 2

这不适用于字典，因为字典值有多种类型(数字、字符串、子字典等)。

我建议创建真正的类型，而不是字典，这最终会减少工作：

// types
public record MyValue(int BrandId, int CollectionId, Identity Identity, [...]){}
public record Identity(string Sku, string, Ean, string Isbn, string Barcode){}
...

// use it
var data = new MyValue(123, 456, new("mysku", "myean", "myisbn", "mybarcode"));
var response = await httpClient.postAsJsonAsync(data);

你可以在这里找到文档：

• https://docs.microsoft.com/en-us/dotnet/api/system.net.http.json.httpclientjsonextensions.postasjsonasync?view=net-5.0
• https://docs.microsoft.com/en-us/dotnet/csharp/whats-new/csharp-9#record-types

您还必须告诉json序列化程序将C#属性命名样式(AbcDef)转换为驼峰大小写(abcDef)，请参阅：ASP.NET Core 3.0 System.Text.Json Camel Case Serialization

请注意，这是c# 9 (.net 5.0)

如果你想做"freestyle"，看看dynamic类型的https://docs.microsoft.com/en-us/dotnet/csharp/language-reference/builtin-types/reference-types#the-dynamic-type (观点:不要)
