如何使用 Asp.Net C查询mongodb文档中的所有文件#

Question

我试图使用.NET驱动程序查询mongodb文档，我想在不创建类对象的情况下获取特定文档中的所有字段，因为这些文档是动态生成的，我只知道一个字段名，即，_id。如何获取整个文档

public class usermodal
{
    public string _id { get; set; }
    public string Image { get; set; }

}
protected  void Page_Load(object sender, EventArgs e)
{
    // //BsonDocument modal = new BsonDocument;
    string id = "e0b4a7b7-096a-4a8a-b942-83fccf81e6c5";
    var client = new MongoClient(mongocon);
    var db = client.GetDatabase("Mydb");
    var collection = db.GetCollection<usermodal>("new");
    var filter = Builders<usermodal>.Filter.Eq("_id", id); //filter the bson document based on ID

    // var list = collection.Find(filter).ToList();
    //var filterx = new BsonDocument("_id", "e0b4a7b7-096a-4a8a-b942-83fccf81e6c5");

    var result = collection.Find(filter).ToList();


    GridView1.DataSource = result;
    GridView1.DataBind();

当字段已知时，这工作正常

    protected  void Page_Load(object sender, EventArgs e)
{
    // //BsonDocument modal = new BsonDocument;
    string id = "e0b4a7b7-096a-4a8a-b942-83fccf81e6c5";
    var client = new MongoClient(mongocon);
    var db = client.GetDatabase("Mydb");
    var collection = db.GetCollection<dynamic>("new");
    var filter = Builders<dynamic>.Filter.Eq("_id", id); //filter the bson document based on ID

    // var list = collection.Find(filter).ToList();
    //var filterx = new BsonDocument("_id", "e0b4a7b7-096a-4a8a-b942-83fccf81e6c5");

    var result = collection.Find(filter).ToList();


    GridView1.DataSource = result;
    GridView1.DataBind();
