Using MongoDatabase class instead of MongoDatabaseImpl

Question

I need to set profiling level via Mongo C# Driver.

Client.GetDatabase("test") returns IMongoDatabase interface which resolves to MongoDB.Driver.MongoDatabaseImpl at runtime.

According to MongoDB .NET Driver API Documentation MongoDatase class has a SetProfilingLevel method which I can not cast to at runtime.

BTW I also installed Legacy Driver version 2.0.1 since documentation says that SetProfilingLevel method is in it.

New MongoDB driver (at least 2.3) doesn't have specific method for changing profiling level.
But you can execute any command using RunCommandAsync.

public async Task SetProfilingLevelAsync(IMongoDatabase database, int level)
{
    var command = new BsonDocumentCommand<BsonDocument>(new BsonDocument("profile", level));
    await database.RunCommandAsync(command);
}

You may want to add optional slowms parameter also.

This method is indeed in legacy version of driver. So first intall legacy version and then:

var client = new MongoServer(new MongoServerSettings());
var db = client.GetDatabase("db_name");
db.SetProfilingLevel(ProfilingLevel.All);
