C# MongoDB过滤器返回整个对象

using MongoDB.Bson;
using MongoDB.Driver;

// 创建MongoDB连接
var client = new MongoClient("mongodb://localhost:27017");
var database = client.GetDatabase("your_database_name");
var collection = database.GetCollection<BsonDocument>("your_collection_name");

// 设置过滤器
var filter = Builders<BsonDocument>.Filter.Eq("your_field_name", "your_value");

// 查询并返回整个对象
var result = collection.Find(filter).ToList();

// 遍历结果
foreach (var document in result)
{
    // 处理返回的整个对象
    Console.WriteLine(document);
}
