Mongo使用asp.net连接问题

Question

I wrote these lines in My Application start event:

    var mongo = new Mongo();
    mongo.Connect();
    var blog = mongo.GetDatabase("Blog");
    mongo.Disconnect();

but on this line: mongo.Connect(); it gave me this error:

No connection could be made because the target machine actively refused it 127.0.0.1:27017

I am a beginner using Mongodb and i am just try to make sample code to see it's power.
So i have no idea how to solve this problem.

I am using VS2008 with MongoDB.Driver on Windows7.

UPDATE

I got also that the same problem is happening while trying this tutorial: http://www.mongodb.org/display/DOCS/Tutorial#Tutorial-GettingADatabaseConnection using the shell.

Answer 1

For this problem what you can do is just check your dbpath in mongod.cfg file in your mongo folder.

It should be the exact path of your data folder like for example dbpath=e:\\data\\db .

Answer 2

i found the problem, the problem that mongodb is pointing to the default database directory c:\\data\\db

now i will try to get how to change this directory to another one.

Answer 3

When this problem occurs, you must delete the mongod.lock file. MongoDB then immediately creates a new lock, and the service becomes available again.

BTW, in order to work with MongoDB more easily, check out MongoVUE at http://www.mongovue.com .
