c# mongodb如何按id搜索，按字符串数组过滤

using MongoDB.Driver;
using MongoDB.Bson;

public class MyClass
{
    private IMongoCollection<MyDocument> collection;

    public MyClass()
    {
        // 连接到MongoDB数据库
        var client = new MongoClient("mongodb://localhost:27017");
        var database = client.GetDatabase("mydb");
        
        // 获取集合
        collection = database.GetCollection<MyDocument>("mycollection");
    }

    public MyDocument GetById(string id)
    {
        // 构建查询条件
        var filter = Builders<MyDocument>.Filter.Eq("_id", ObjectId.Parse(id));
        
        // 执行查询
        return collection.Find(filter).FirstOrDefault();
    }
}

public class MyDocument
{
    public ObjectId Id { get; set; }
    // 其他属性
}
