How to insert data into a mongodb collection using the c# 2.0 driver?

  1. I'm using the MongoClient in my c# console application to connect to MongoDB

https://github.com/mongodb/mongo-csharp-driver/releases/tag/v2.0.0-rc0

  1. My code

      class Program
   {
       static void Main(string[] args)
       {
        const string connectionString = "mongodb://localhost:27017";

        // Create a MongoClient object by using the connection string
        var client = new MongoClient(connectionString);

        //Use the MongoClient to access the server
        var database = client.GetDatabase("test");

        var collection = database.GetCollection<Entity>("entities");

        var entity = new Entity { Name = "Tom" };
        collection.InsertOneAsync(entity);
        var id = entity._id;          
    }
}

public class Entity
{
    public ObjectId _id { get; set; }
    public string Name { get; set; }
}

  2. After successfully running the code above, I'm unable to find this record in the MongoDB database using this command:

    db.entities.find().pretty()

What's wrong with my code?

for .net 4.5 and greater versions and mongodriver 2x series follow the below code

var Client = new MongoClient();
var MongoDB = Client.GetDatabase("shop");
var Collec = MongoDB.GetCollection<BsonDocument>("computers");
var documnt = new BsonDocument
{
    {"Brand","Dell"},
    {"Price","400"},
    {"Ram","8GB"},
    {"HardDisk","1TB"},
    {"Screen","16inch"}
};
Collec.InsertOneAsync(documnt);
Console.ReadLine();

The reason is you need to wait to get the store to create the document. In this case collection.InsertOneAsync(entity); the execution exit before creating the document.

Either Console.ReadKey() or collection.InsertOneAsync(entiry).Wait() or any other form of stopping exit for a fraction of second will do the trick.

This is the method I created for inserting data into MongoDB, which is working fine now.

static async void DoSomethingAsync()
{
    const string connectionString = "mongodb://localhost:27017";

    // Create a MongoClient object by using the connection string
    var client = new MongoClient(connectionString);

    //Use the MongoClient to access the server
    var database = client.GetDatabase("test");

    //get mongodb collection
    var collection = database.GetCollection<Entity>("entities");
    await collection.InsertOneAsync(new Entity { Name = "Jack" });
}
