在使用ASP.NET API Core2.1时如何在MongoDB中操作多个集合

using MongoDB.Driver;

var client = new MongoClient("mongodb://localhost:27017");

var database = client.GetDatabase("your_database_name");

var collection1 = database.GetCollection<YourModel>("collection1_name");
var collection2 = database.GetCollection<YourModel>("collection2_name");

// 插入文档
var document = new YourModel { Name = "John", Age = 25 };
collection1.InsertOne(document);

// 查询文档
var filter = Builders<YourModel>.Filter.Eq("Name", "John");
var result = collection1.Find(filter).ToList();

// 更新文档
var update = Builders<YourModel>.Update.Set("Age", 30);
collection1.UpdateOne(filter, update);
