C#简单操作MongoDB

Posted 2022-02-23 bcbobo21cn

新建一个窗体程序；使用Nuget安装mongodb.driver；或者直接引用dll如下；

代码；

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using MongoDB.Bson;
using MongoDB.Driver;

namespace mgtest

    public partial class Form1 : Form
    
        protected static IMongoDatabase _database;
        protected static IMongoClient _client;

        public Form1()
        
            InitializeComponent();
        

        private void Form1_Load(object sender, EventArgs e)
        

        

        private void button1_Click(object sender, EventArgs e)
        
            const string collectionName = "村子";
            string strCon = "mongodb://127.0.0.1:27017/mymgtest";
            var mongoUrl = new MongoUrlBuilder(strCon);
            string databaseName = mongoUrl.DatabaseName;
            _client = new MongoClient(mongoUrl.ToMongoUrl());
            _database = _client.GetDatabase(databaseName);

            var collection = _database.GetCollection<BsonDocument>(collectionName);
            var filter = new BsonDocument();

            var list = Task.Run(async () => await collection.Find(filter).ToListAsync()).Result;

            list.ForEach(p =>
            
                textBox1.Text = textBox1.Text + p["name"].ToString() + "，" + p["人数"].ToString() + "，" + p["位置"].ToString() + Environment.NewLine;
            );
        
    

输出如下； 

 

这是前文创建的mongodb数据库；
