Usage

Employee Model

using MongoDB.Bson;
using MongoDB.Bson.Serialization.Attributes;

public  class Employee
{
    [BsonId]
    [BsonRepresentation(BsonType.ObjectId)]
    public ObjectId Id { get; set; }

    public string Name { get; set; }

    public DateTime Birthday { get; set; }
}

Open connection to MongoDB (using statement)

using MongoDB;

string connectionString = "mongodb://localhost:27017";
string databaseName = "EmployeeDB";

using (Crud db = new Crud(connectionString, databaseName))
{
    // do your things here ...
}

Insert Employee data

var emp = new Employee()
{
    Name = "Jone Doe",
    EmpID = 1000,
    Birthday = Convert.ToDateTime("1981-04-13")
};
await db.InsertRecord("Employee", emp);

Insert unique record

var emp = new Employee()
{
    Name = "Jone Doe",
    EmpID = 1000, // Unique ID
    Birthday = Convert.ToDateTime("1981-04-13")
};
await db.InsertUniqRecord("Employee", emp, "EmpID");

Load all records of a collection

var rec = await db.LoadRecords<Employee>("Employee");

Load records by index

var rec = db.LoadRecordByIndex<Employee>("Employee", "Name", "Jone Doe");

Load one record by index

var rec = db.LoadOneRecordByIndex<Employee>("Employee", "Name", "Jone Doe");

Load a record by Id

First, we have to get ObjectId before doing this. To get an ObjectId you can use any method as shown in above.

ObjectId ObjectID = new ObjectId("6366675caf5305273398cfbd");

var rec = db.LoadRecordById<Employee>("Employee", ObjectID);

Search case

Below example will display all records from Employee collection, which Name starts from 'J'

var rec = db.SearchCase<Employee>("Employee", "Name", "J");

Search between two dates

This example will display Employees who has birthday between selected dates.

DateTime startDate = Convert.ToDateTime("1980-04-20");
DateTime endDate = Convert.ToDateTime("1990-04-20");

var rec = await db.LoadBetweenDates<Employee>("Employee", "Birthday", startDate, endDate);

Delete all records by index

This will delete all records where EmpID is, '1000'. However, if EmpID is unique this will also delete a single record.

db.DeleteRecordByIndex<Employee>("Employee", "EmpID", "1000");

Delete a record

To delete a record we have to get ObjectId

db.DeleteRecord<Employee>("Employee", ObjectID);

Updating a record

First we need to load record, and then update.

var oneRec = db.LoadRecordById<Employee>("Employee", ObjectID);
oneRec.Id = ObjectID; // or, oneRec.Id = oneRec.Id;
oneRec.Name = "Jone Doe Smith"

This will update Employee Name.

db.UpsertRecord("Employee", oneRec.Id, oneRec);

Bonus configuration for database connection.

Create a new class name, dbConn

namespace MongoDB;
public class dbConn
{
    public static string connString = "mongodb://localhost:27017";
    public static string dbName = "EmployeeDB";
}

And then you can run CRUD operations, as below

using MongoDB;

using (Crud db = new Crud(dbConn.connString, dbConn.dbName))
{
    // do your things here .... 
}

A full example for insert

using MongoDB;

public class MyProject
{
    public void InsertData()
    {
        using (Crud db = new Crud(dbConn.connString, dbConn.dbName))
        {
            var emp = new Employee()
            {
                Name = "Jone Doe",
                EmpID = 1000, // Unique ID
                Birthday = Convert.ToDateTime("1981-04-13")
            };
            await db.InsertUniqRecord("Employee", emp, "EmpID");
        }
    }
}
