如何使用c#检查mongodb中的multipal值

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

var database = client.GetDatabase("your_database_name");
var collection = database.GetCollection<BsonDocument>("your_collection_name");

var filter = Builders<BsonDocument>.Filter.Eq("your_field_name", "your_value");
var documents = collection.Find(filter).ToList();

foreach (var document in documents)
{
    var fieldValue = document.GetValue("your_field_name");
    // 处理多值字段的值
}
