如何使用C#使我的泛型方法成为选择从mongoDB返回哪些列的方法？

public IEnumerable<T> SelectColumns<T>(IMongoCollection<T> collection, params string[] columns)
{
    var projection = Builders<T>.Projection.Include(columns);
    var result = collection.Find(Builders<T>.Filter.Empty).Project<T>(projection).ToList();
    return result;
}

// 创建MongoDB客户端
var client = new MongoClient("mongodb://localhost:27017");

// 获取数据库和集合
var database = client.GetDatabase("mydb");
var collection = database.GetCollection<MyModel>("mycollection");

// 调用泛型方法选择返回指定列
var result = SelectColumns(collection, "Name", "Age");

// 遍历结果
foreach (var item in result)
{
    Console.WriteLine($"Name: {item.Name}, Age: {item.Age}");
}
