How to use MongoDB with C#

C-programming

C Programming

Hello,

in this article we will examine how MongoDB is integrated with C#.

NoSQL systems are grouped into three groups based on document-based, key/value-based, and graphic-based. MongoDB is document-based and is the easiest to use.

The current version of mongodb is 2.4.6. http://www.mongodb.org/downloads you can download it free of charge from.

After downloading what is appropriate to our system C: under the folder called mongodb create a zip file into this folder.

Keeping our database files C:datadb our folder needs to be found. ( Note : This folder is fixed, and should not be in a different job. )

try
02
{
03
var conn = new MongoDB.Mongo();
04
conn.Connect();
05
MessageBox.Show("Connected");
06
}
07
catch (Exception ex)
08
{
09
MessageBox.Show(ex.Message);
10
}

try

{

var conn = new MongoDB.Mongo();

conn.Connect();

MessageBox.Show("Connected");

}

catch (Exception ex)

{

MessageBox.Show(ex.Message);

}

the above code will test our connection to our database.

Create a class called Personel

class Personel
{
public string personelAdi { set; get; }
public int numarasi {set; get; }
public Personel()
{
}
public override string ToString()
{
return this.personelAdi;
}
}

class Personel

{

public string personelAdi { set; get; }

public int numarasi {set; get; }

public Personel()

{

}

public override string ToString()

{

return this.personelAdi;

}

Insert

try
{
var mongo = new MongoDB.Mongo();
mongo.Connect();
var db = mongo.GetDatabase("DemoDB");
var coll = db.GetCollection<Personel>();
coll.Save(p);
MessageBox.Show("kaydedildi");
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}

try

{

var mongo = new MongoDB.Mongo();

mongo.Connect();

var db = mongo.GetDatabase("DemoDB");

var coll = db.GetCollection<Personel>();

coll.Save(p);

MessageBox.Show("kaydedildi");

}

catch (Exception ex)

{

MessageBox.Show(ex.Message);

}

Update

public void update(Personel p){
var mongo = new MongoDB.Mongo();
mongo.Connect();
var db = mongo.GetDatabase("Demo");
var coll = db.GetCollection<Personel>();
p.personelAdi = "Duran";
coll.Save(p);
}

public void update(Personel p){

var mongo = new MongoDB.Mongo();

mongo.Connect();

var db = mongo.GetDatabase("Demo");

var coll = db.GetCollection<Personel>();

p.personelAdi = "Duran";

coll.Save(p);

}

Select

public List<Personel> getPersolonels()
{
var mongo = new MongoDB.Mongo();
mongo.Connect();
var db = mongo.GetDatabase("DemoDB");
var personels = db.GetCollection<Personel>().FindAll().Documents;
return personels.ToList() ;
}

public List<Personel> getPersolonels()

{

var mongo = new MongoDB.Mongo();

mongo.Connect();

var db = mongo.GetDatabase("DemoDB");

var personels = db.GetCollection<Personel>().FindAll().Documents;

return personels.ToList() ;

}

As you can see, with MongoDB, database operations can be easily done, such systems in large projects save us from writing long codes.

I share a link to some of the MongoDB management systems :
