C#与mongoDB初始环境搭建

mongoDB官网https://www.mongodb.com/

mongoDB默认安装路径(Windows x64平台)
C:\Program Files\MongoDB\Server\3.4\bin

mongoDB环境变量配置

启动mongoDB服务

> mongod -dbpath D:\mongodb                
> mongo

Visual Studio引用mongoDB

PM> install-package MongoDB.Driver

C#操作详见
https://docs.mongodb.com/ecosystem/drivers/csharp/

 string url = "mongodb://127.0.0.1:27017";
 var client = new MongoClient(url);
 var db = client.GetDatabase("blog");//获取数据库，如果不存在就创建一个
 var collection = db.GetCollection<Post>("post");
 //增
 //for(int i = 1; i < 10000; i++) {
 //    Post post = new Post()
 //    {
 //        Id = i,
 //        Author = "作者" + i,
 //        CreateTime = DateTime.Now,
 //        Issue = false,
 //        Title = "文章" + i,
 //        Details = Guid.NewGuid().ToString(),
 //        Comments = new List<string>() { "评论" + i }
 //    };
 //    collection.InsertOne(post);
 //}

 //查
 //   Console.WriteLine(collection.CountDocuments(c => 1 == 1));
 //  var p5 = collection.Find(p => p.Id == 5).First();
 // Console.WriteLine("{0}在{1}发表了{2}", p5.Author, p5.CreateTime, p5.Title);

 //删
 // collection.FindOneAndDelete<Post>(p => p.Id == 6);
 //var p6 = collection.Find<Post>(p => p.Id == 6).FirstOrDefault();

 //改
 // var filter = Builders<Post>.Filter.Eq("Id", 7);
 // var update = Builders<Post>.Update.Set("Title", "夏天");
 //collection.FindOneAndUpdate<Post>(filter, update);
 //var p7 = collection.Find(f => f.Id == 7).FirstOrDefault();
 // Console.WriteLine("{0}在{1}发表了{2}", p7.Author, p7.CreateTime, p7.Title);

配置mongoDB服务
在mongoDB的安装目录下创建配置文件mongod.cfg，然后再配置文件中添加服务的日志的输出路径（对路径没有强制要求）

systemLog:
    destination: file
    path: D:\mongodb\logs\mongodb.log
storage:
    dbPath: D:\mongodb\data

通过管理员打开cmd.exe

> mongod --config "D:\mongoDB\mongod.cfg" --install --serviceName "MongoDB"
