我有一個復雜的嵌套 JSON 數據結構，下面保存在文件 data.json 中。減少了數據結構，但這將適用于所有 json 數據結構。我將 json 讀取并反序列化為 C# 模型。然后我使用 MongoDB C# 客戶端驅動程序將對象/數據寫入 MongoDB 你如何將這個復雜的對象/數據/模型保存到 MongoDB？復雜的嵌套數據結構，data.json 文件 [ { "property_1": "value_1", "property_2": "value_2", "property_3": { "_some_property_1": 1, "_some_property_2": "some_value_2", "some_property_3": "some_value_3", "some_property_4": "some_value_4" }, "property_4": "value_4", "property_5": "value_5", "iproperty_6": "Nvalue_6", "property_7": "value_7", "property_8": "value_8", "property_9": "value_9" } ]C# ASP.NET Web Api 演示代碼 namespace DemoWebApi.Controllers { public class ValuesController : ApiController { // GET api/values public void Get() { var models = CreateModels(); var client = new MongoClient("mongodb://localhost:27017/admin"); var database = client.GetDatabase("TestDB"); /* THIS DOES NOT WORK IMongoCollection<MODEL> collection = database?.GetCollection<MODEL>("TestCollection"); collection.InsertMany(models); */ }

在隊友的幫助下，這行得通。將您的模型序列化BsonDocument并傳遞BsonDocument給 MongoDB C# 驅動程序插入方法。通過這種方式，您可以使用您的 C# POCO 對象，直到您想要將其持久化到 MongoDB，然后您將其序列化為BsonDocument數組或BsonDocument保存它。因為這個復雜的模型BsonDocument[]解決了我的問題
用這個形狀和結構保存一個復雜的json模型，比下面這個形狀和結構復雜到MongoDB
//Complex json collection/array shape and structure to save as is in MongoDB
[
{
"property_1": "value_1",
"property_2": "value_2",
"property_3": {
"_some_property_1": 1,
"_some_property_2": "some_value_2",
"some_property_3": "some_value_3",
"some_property_4": "some_value_4"
},
"property_4": "value_4",
"property_5": "value_5",
"iproperty_6": "Nvalue_6",
"property_7": "value_7",
"property_8": "value_8",
"property_9": "value_9"
}
]
// This works - code snippets
/*Create a collection of C# POCO from for the json.
// My assumption is you can create C# objects/collections from complex json shape and structure
// Serialize to MongoDB BsonDocument and save*/
var models = new List<Model>{ new Model()}; // Create C# collection from json
string text = JsonConvert.SerializeObject(models);
var bsonDocument = BsonSerializer.Deserialize<BsonDocument[]>(text);
var client = new MongoClient("mongodb://localhost:27017/admin");
var database = client.GetDatabase("TestDB");
IMongoCollection<BsonDocument> collection = database?.GetCollection<BsonDocument>("TestCollection");
collection.InsertMany(bsonDocument);
