Help with error

[PRinCE Dinson]

I am trying to insert, update, delete and retrieve data from mongodb
using VS2010, and C# Driver 1.3.1


Here is the C# code (not the whole code file, only the relevant part)
i use:

**************************
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Drawing;
using MongoDB.Bson;
using MongoDB.Driver;
using MongoDB.Bson.IO;

using MongoDB.Bson.Serialization.Attributes;
using MongoDB.Bson.Serialization.Conventions;
using MongoDB.Bson.Serialization.IdGenerators;
using MongoDB.Bson.Serialization.Options;
using MongoDB.Bson.Serialization.Serializers;
using MongoDB.Driver.Builders;
using MongoDB.Driver.GridFS;
using MongoDB.Driver.Wrappers;
********************************

string connectionString = "mongodb://localhost"; // Declared
outside the function
//
so that available throughout
//
the whole class for each
//
4 functions namely
//
Insert(), Update(), Delete()
//
and Display()
-
-
-
public int Insert(BO.Data data) // One
of the functions
{
MongoServer server = MongoServer.Create(connectionString);
try
{
MongoDatabase myMongoDB =
server.GetDatabase("myMongoDB");

//
On First run, the database
//
myMongoDB doesn't exist
//
and has to be created. MongoDB
//
does this automatically, i think.
//
Next run onwards, just select
//
this database.

MongoCollection<BO.Data> myData =
myMongoDB.GetCollection<BO.Data>("myData");

//
On First run, the collection
//
myData doesn't exist
//
and has to be created. MongoDB
//
does this automatically, i think.
//
Next run onwards, just select
//
this collection.
BO.Data newData = new BO.Data(); //Object of
class Data. has members
//
string, int and System.Drawing.Bitmap
newData.FirstName = data.FirstName;
newData.LastName = data.LastName;
newData.Pic = new Bitmap(data.Pic);
newData.PersonID = data.PersonID;
newData.Age = data.Age;

myData.Insert(newData); // Insert the
Data into myData
return (1);
}
catch
{
throw;
}
finally
{
server.Disconnect();
}

}

It cannot even get into the try loop coz some error is happening, and
it goes to the catch-finally part.

I thought maybe some thing wrong with the server connection, so i ran
mongod.exe from a CMD console. I got this error:

I used taskmanager to see whether there was much network load, but it
doesnot show anything as such...

netstat -n gives this output

I dont see anything regarding 0.0.0.0:27017 here... please help

Windows Firewall is off. No 3rd party firewall or AV running.
OS is XP pro, version 2002, service pack 3
Visual Studio 2010 (no sp installed right now, but will update in a
day or 2 to SP1).
MongoDB downloaded on 23Feb 2012 (the then latest stable version) and
the c# Driver is the officially supported one, version 1.3.1

If you don't specify parameter, mongod will start on port 27017 same as mongos. If you don't plan to try out sharding, you should probably only start up mongod.

Note that to view listened ports, you should use netstat -na to view all sockets.
