将JArray转换为Dynamic []，以便NEST的IndexMany可以工作]] << [

Question

问题描述：

我需要接收

JSON对象数组（几乎具有任何形状），并使用函数IndexMany（或一些类似的批量索引函数）将它们存储到ES数据库。我发现了一个笨拙的解决方案，但有一个缺点-它无法正确设置ES中的_id属性（根据JSON对象中的id属性）。 而且我也想知道是否有任何更优雅的方式来实现我的目标，而无需将每个JArray项目都转换为字符串并返回到ExpandoObject。

附加信息：

Elasticsearch DB 7.5.1巢（7.6.1）Newtonsoft.Json（12.0.3）

TLDR：

以下代码是否有任何优雅的解决方案：

var settings = new ConnectionSettings(new Uri("http://localhost:9200")).DefaultIndex("people");
var client = new ElasticClient(settings);

// this string represents incomming JSON message
string json = @"[
    {
        ""id"": ""1"",
        ""name"": ""Andrej"",
        ""surname"": ""Burak"",
        ""dob"": ""1921-11-10T00:00:00+00:00""
    },
    {
        ""id"": ""2"",
        ""name"": ""Franta"",
        ""surname"": ""Dobrota"",
        ""dob"": ""1933-10-05T00:00:00+00:00""
    },
    {
        ""id"": ""3"",
        ""name"": ""Milos"",
        ""surname"": ""Ovcacek"",
        ""dob"": ""1988-05-05T00:00:00+00:00""
    }
]";


JArray jArray = JArray.Parse(json);

foreach (var jtoken in jArray)
{
    var jobj = (JObject)jtoken;
    jobj.Add("DbCreated", JToken.FromObject(DateTime.UtcNow));
    jobj.Add("DbCreatedBy", JToken.FromObject("authors name"));
}

//working, but seems to me a bit too clumsy to convert every item to string and then back to dynamic object
var converter = new ExpandoObjectConverter();
dynamic[] dlst = jArray.Select(t => (dynamic)JsonConvert.DeserializeObject<ExpandoObject>(t.ToString(), converter)).ToArray();

//not working cast 
dynamic[] dlstNW = jArray.ToObject<dynamic[]>();

var indexManyResponse = client.IndexMany(dlst); //working partially (but not using ID as index)
var indexManyResponseNotWorking = client.IndexMany(jArray); //not working
var indexManyResponseNotWorking2 = client.IndexMany(dlstNW); //not working


// expected behavior
dynamic[] jsondyn = new dynamic[]
{
    new { Id = "1", Name = "foo" },
    new { Id = "2", Name = "bar" },
    new { Id = "3", Name = "baz" },
};
var indexManyResponseWithIndex = client.IndexMany(jsondyn); //working perfectly, but don't know how to acieve this
