MongoDB is 3.2.7 version

Recently in the Learning MongoDB database found on the Internet is not 2. X version of the following, since the drive from 2. X was modified a lot later, and LINQ now 2 is not supported. X is supported, too.

Mongodb Start-up service don't say it now. Basic operations

On the code:

First define a model to test the operation

public class persion{    //reference using MongoDB.Bson.Serialization.Attributes;    [Bsonid]    public string _id;    public string name;public int age;    public string Email;    public string TableName     {        get{return "Persion";}}    }

Add Mongob C#driver to the reference, which can be added via NuGet or directly to the website and then added to the project.

Configuration creation Mongodbclient Note: "Previous version is Mongoserver" and ready to configure

The address can be either remote or local, and is now using the local

Database connection string        static string conn = "mongodb://127.0.0.1:27017";        Database name        static string database = "appdb";//Database name        static Mongourl url = new Mongourl (conn);        static Mongoclient ci = new mongoclient (URL);//Create mongoclient        static imongodatabase db = Ci. Getdatabase (database);//Get Databases

Here's how the data is done

Add data public static void Insertuser (persion per = null) {//Link to table, database does not exist in table okay, no mongodb will automatically create a C Ollection//("Persion") collection is also called table var colls = db.            Getcollection<persion> ("Persion"); per = new Persion {_id = Guid.NewGuid ().            ToString (), Name = "[email protected]", age = 12}; Colls.        Insertone (per); }//Modify public static void Updat () {//get data var colls = db.            Getcollection<persion> ("Persion"); var model = Colls. Find (c = c.name = = "Ynland"). FirstOrDefault ();//filter data//conditions. Equivalent to where the filte.eq equals the equal sign Filter.eq ("field", matching value) var Filter = Mongodb.driver.builders<persion>. Filter.eq ("Name", model.)            Name); Modified value, set ("Field", "Modified value") Note that the field matches the field in the database, the mismatch cannot be found to automatically create a new field and assign the value var update = Mongodb.driver.builders<persion>.           Update.set ("Age", "66"); Colls. Updateone (filter, update);//Modify a data updatEresult res= Colls.            Updatemany (filter, update);//Multiple modifications} public static void Deleteinfo () { var colls = db.            Getcollection<persion> ("Persion"); Colls.        Deleteone (c = c.age = = 100); }//Get data public static void Getallinfo () {///data type to be consistent to not serialize var t = db. Getcollection<persion> ("Persion"). Find (c = c.name!=string.            Empty);        list<persion> list = T.tolist (); }

Filter at the time of modification, and set convenient place

Filter the Criteria filter.xxx ("Field name", "companion value") to filter

Set (). Set (). Set (). Set (). Sets (). To assign a value like this
