无法从ASP.Net应用程序连接到MongoDB

Question

I downloaded the driver (version 2.4.4) and first I just want to connect and read some existing data.

So I tried everything I found online. Here's my code:

MongoClientSettings settings = new MongoClientSettings();
settings.Server = new MongoServerAddress(connectionString, 27017);
var client = new MongoClient(settings);

my connectionString looks like this:

mongodb://x.x.x.x

and the error I'm getting is:

 An exception of type 'System.ArgumentException' occurred in 
 MongoDB.Driver.Core.dll but was not handled in user code

 Additional information: 'mongodb://x.x.x.x:27017' is not a valid end point.

I couldn't find this error anywhere online. Please help :)

edit: I'm not using localhost and am running a real IP. the xxxx is just for the question purpose.

Answer 1

Well xxxx is not a valid address. If you're running mongodb locally you can use:

var url = new MongoUrl("mongodb://localhost:27017");
var client = new MongoClient(url);

Answer 2

You need to get rid of the "mongodb://" part of your host parameter. So instead of

settings.Server = new MongoServerAddress("mongodb://x.x.x.x", 27017);

use

settings.Server = new MongoServerAddress("x.x.x.x", 27017);

or even just

settings.Server = new MongoServerAddress("x.x.x.x");

since 27017 is the default port.
