C # operations MongoDB Getting Started

Disclaimer: This article is a summary of my experience in learning MongoDB for a week. One to give yourself a backup, and second to the same as I just contact MongoDB small white to share, what problem, give a bit please more magnanimous.

1. MongoDB Installation and Configuration

(1) Download:

MongoDB official website Https://www.mongodb.com/download-center

Go to the official website download page, you will find that the version is Windows Server ... But do not worry, I win0 test can also use, so be assured that the bold download can be. The installation process is relatively simple, the next step is enough, not much to say.

(2) configuration

In the "D:\MongoDB\bin (this directory is the Bin folder's directory, and the default location, the following command-line operation is basically under this directory)" directory under the new "Data" folder, it will be stored as the data root folder.

Create a new "log" folder in the "D:\MongoDB\bin" directory as the log folder.

Configure the MONGO service side:

Open the CMD window as an administrator and enter the command as follows:
> D:
> CD MongoDB

>CD bin
> Mongod--dbpath "D:\MongoDB\data"

Then in the browser input: http://localhost:27017/, you can see the following prompt:

You is trying to access MongoDB on the native driver port. For HTTP diagnostic access, add the port number (may not be the same as this, there are words on the line)

Thus, the MongoDB database service has been successfully started.

　　　　　　Package Service:

Or run cmd, go to the bin directory and execute the following command
>mongod-dbpath "D:\MongoDB\data"-logpath "D:\MongoDB\log\MongoDB.log"-install-servicename "MongoDB"

Here--mongodb.log is the start of the log file,--servicename "MongoDB" service named MongoDB.

Then start the MongoDB service

> D:\mongodb>net START MongoDB

After the service starts successfully, you can test

Enter the bin directory, input MONGO display the following information, the service started successfully.

E:\Program Files\mongodb\bin>mongo
MongoDB Shell version:3.2.9
Connecting To:test
>

The installation configuration is complete.

2. Installing MongoDB C # Driver

Open C #, new project, click Tools >nuget Package Manager > Manage NuGet packages for solution > online,

Search for MongoDB in the search bar

Install Mongodb.driver,mongodb.bson,mongodb.driver.core three packages.

And then add the reference

Using Mongodb.driver;
Using Mongodb.bson;

3. Code

The next is to write the code, the following is the simplest I write to delete and change the operation (level Limited, do look)

Find (document); - Console.WriteLine (Document1. ToString ()); Wu  -             //Update Data About             varFilter = Builders<bsondocument>. Filter.eq ("name","MongoDB"); $             varUpdate = Builders<bsondocument>. Update.set ("name","Ghazi"); -  - collection. Updatemany (filter, update); -  A             //Delete Data +             varFilter1 = Builders<bsondocument>. Filter.eq ("Count",101); the  - collection. Deletemany (filter1); $  theBsondocument Document2 =Newbsondocument (); theDocument2. ADD ("name","MongoDB"); theDocument2. ADD ("type","Database"); theDocument2. ADD ("Count","1"); -  in collection. Insertone (Document2); the         } the     } About}
