MongoDB C#驱动程序:以不太冗长的方式更新？

using MongoDB.Driver;
using System;

public class User
{
    public ObjectId Id { get; set; }
    public string Name { get; set; }
    public int Age { get; set; }
}

public class Program
{
    private static void Main(string[] args)
    {
        var client = new MongoClient("mongodb://localhost:27017");
        var database = client.GetDatabase("testdb");
        var collection = database.GetCollection<User>("users");

        // 更新单个文档
        var filter = Builders<User>.Filter.Eq(u => u.Name, "John Doe");
        var update = Builders<User>.Update.Set(u => u.Age, 30);
        collection.UpdateOne(filter, update);

        // 更新多个文档
        var filterMany = Builders<User>.Filter.Where(u => u.Age < 25);
        var updateMany = Builders<User>.Update.Inc(u => u.Age, 1);
        collection.UpdateMany(filterMany, updateMany);
    }
}
