How to check connection to mongodb

Question

I use MongoDB drivers to connect to the database. When my form loads, I want to set up connection and to check whether it is ok or not. I do it like this:

var connectionString = "mongodb://localhost";
var client = new MongoClient(connectionString);
var server = client.GetServer();
var database = server.GetDatabase("reestr");

But I do not know how to check connection. I tried to overlap this code with try-catch, but to no avail. Even if I make an incorrect connectionString, I still can not get any error message.

Answer 1

To ping the server with the new 3.0 driver its:

var database = client.GetDatabase("YourDbHere");

database.RunCommandAsync((Command<BsonDocument>)"{ping:1}")
        .Wait();

Answer 2

There's a ping method for that:

var connectionString = "mongodb://localhost";
var client = new MongoClient(connectionString);
var server = client.GetServer();
server.Ping();

Answer 3

full example for 2.4.3 - where "client.GetServer()" isn't available. based on "Paul Keister" answer.

client = new MongoClient("mongodb://localhost");
database = client.GetDatabase(mongoDbStr);
bool isMongoLive = database.RunCommandAsync((Command<BsonDocument>)"{ping:1}").Wait(1000);

if(isMongoLive)
{
    // connected
}
else
{
    // couldn't connect
}
