安装MongoDB（最好装C盘）:     https://www.runoob.com/mongodb/mongodb-window-install.html

安装可视化软件Robo3T：https://robomongo.org/

连接MongoDB实例：

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using MongoDB.Bson;
using MongoDB.Driver;
 
 
 
public class MongodbTest : MonoBehaviour
{
    // Start is called before the first frame update
    void Start()
    {
        InsertData();
    }
 
    private IMongoCollection<BsonDocument> DatabaseConn()
    {
 
        var client = new MongoClient("mongodb://localhost");
        var database = client.GetDatabase("test"); //数据库名称
        var collection = database.GetCollection<BsonDocument>("WAWA");//连接的表名
 
        return collection;
    }
 
    public void InsertData()
    {
        var document = new BsonDocument{
        {"aa",11},
        {"bb",22},
        {"cc",new BsonDocument{
            {"x",33},
            {"y",44}
        }}
    };
        var collection = DatabaseConn();
        collection.InsertOne(document);
    }
}
