如何通过在 mongo C# 驱动程序中仅使用连接字符串来`ListCollections`？

Question

I'm instantiating MongoClient with full connection string which includes DB :

MongoClient dbClient = new MongoClient("mongodb://***:***@***:27017/myDb");
var dbList = dbClient.ListDatabases();
IMongoDatabase db = dbClient.GetDatabase("myDb");
var collList = db.ListCollections().ToList();
... 

This works. But -

If the connection string already includes myDb , then why do I need to write again :

dbClient.GetDatabase("myDb");

?

I've already written myDb in the connection string.

Question:

Is there any option to ListCollections of the DB which already mentioned in the connection string?

Answer 1

One option is to just pull out the database name from the connection string. That might sound a bit messy, but MongoUrl makes it nice and easy. Here's an example:

var connectionString = "...";
var dbName = MongoUrl.Create(connectionString).DatabaseName;

// ...

IMongoDatabase db = dbClient.GetDatabase(dbName);
