Use MongoDB C # official driver to operate MongoDB

Use MongoDB C # official driver to operate MongoDB

To use MongoDB in C #, you must first have a C # drive supported by MongoDB. C # has many types of drivers, such as samus. Most of the Implementation ideas are similar. Here we first use the official mongo-csharp-driver. The current version is 1.7.0.4714.

:

Http://github.com/mongodb/mongo-csharp-driver/downloads

After compilation, two dll files are obtained.

MongoDB. Driver. dll: as the name suggests, the Driver

MongoDB. Bson. dll: serialization, Json-related

Then reference the two dll files in our program.

The following section briefly demonstrates how to use C # to add, delete, modify, and query MongoDB.

Program. cs

Using System;
Using MongoDB. Driver;
Using MongoDB. Bson;

Namespace ConsoleApplication1
{
Class Program
{
Static void Main (string [] args)
{
// Database connection string
String conn = "mongodb: // FIG: 27017 ";
// Database Name
String database = "RsdfDb ";
String collection = "Act_User ";

Login Server mongodb = Login server. Create (conn); // connect to the database
Repeated database connected database = mongodb. GetDatabase (database); // select the database Name
Collections collection collections collection = collections database. GetCollection (collection); // select a collection, which is equivalent to a table
Mongodb. Connect ();

// Normal insert
Var o = new {UserID = 0, UserName = "admin", Password = "1 "};
Collections collection. Insert (o );

// Insert an object
User user = new User {UserID = 1, UserName = "chenqp", Password = "1 "};
Collections collection. Insert (user );

// Insert BsonDocument
BsonDocument bd = new BsonDocument ();
Bd. Add ("UserID", 2 );
Bd. Add ("UserName", "yangh ");
Bd. Add ("Password", "1 ");
Collections collection. Insert (bd );

Console. ReadLine ();

}
}
}

User. cs

Using MongoDB. Bson;

Namespace ConsoleApplication1
{
Class User
{
// The _ id attribute must be available; otherwise, an error occurs when updating data: "Element '_ id' does not match any field or property of class ".
Public ObjectId _ id; // BsonType. ObjectId corresponds to MongoDB. Bson. ObjectId
Public int UserID {get; set ;}
Public string UserName {get; set ;}
Public string Password {get; set ;}
}
}

The shell interface is as follows:
