问题
I have read through the mongodb documentation and cannot seem to find out how to create a new database. For example, in the documentation it says I can access the "test" database like this:
db.test.find()
Now what if I want to create my own database using syntax like this:
db.MyDB.find()
Also, is there any documentation I can read online I can further read about creating databases and collections using the DOS interface and the c# driver?
回答1:
I may be wrong, but buried in this documentation it looks like the call to GetDatabase on the server object will actually create the database if it has not already been created.
So, the C# line:
server.GetDatabase("myDB");
Will create a new database named myDB the first time it is called.
From the documentation:
GetDatabase maintains a table of MongoDatabase instances it has returned before, so if you call GetDatabase again with the same parameters you get the same instance back again.

There is no specific API/command required to create a DB in mongo. It creates it automatically when required. Read this article. to understand this in detail.

MongoDB driver has a feature where if a collection does not already exist then it automatically creates one. you can also use umongo an equivalent of Sql server management studio. This video explains a clear sample to start off with https://www.youtube.com/watch?v=6x0-vHHHpv8
