C# Question

Accessing Google Spreadsheets with C# using Google Data API

I'm having some information in Google Spreadsheets as a single sheet.
Is there any way by which I can read this information from .NET by providing the google credentials and spreadsheet address. Is it possible using Google Data APIs.
Ultimately I need to get the information from Google spreadsheet in a DataTable.
How can I do it? If anyone has attempted it, pls share some information.

According to the .NET user guide:

Download the .NET client library:

Add these using statements:

using Google.GData.Client;
using Google.GData.Extensions;
using Google.GData.Spreadsheets;


SpreadsheetsService myService = new SpreadsheetsService("exampleCo-exampleApp-1");
myService.setUserCredentials("", "mypassword");

Get a list of spreadsheets:

SpreadsheetQuery query = new SpreadsheetQuery();
SpreadsheetFeed feed = myService.Query(query);

Console.WriteLine("Your spreadsheets: ");
foreach (SpreadsheetEntry entry in feed.Entries)

Given a SpreadsheetEntry you've already retrieved, you can get a list of all worksheets in this spreadsheet as follows:

AtomLink link = entry.Links.FindService(GDataSpreadsheetsNameTable.WorksheetRel, null);

WorksheetQuery query = new WorksheetQuery(link.HRef.ToString());
WorksheetFeed feed = service.Query(query);

foreach (WorksheetEntry worksheet in feed.Entries)

And get a cell based feed:

AtomLink cellFeedLink = worksheetentry.Links.FindService(GDataSpreadsheetsNameTable.CellRel, null);

CellQuery query = new CellQuery(cellFeedLink.HRef.ToString());
CellFeed feed = service.Query(query);

Console.WriteLine("Cells in this worksheet:");
foreach (CellEntry curCell in feed.Entries)
    Console.WriteLine("Row {0}, column {1}: {2}", curCell.Cell.Row,
        curCell.Cell.Column, curCell.Cell.Value);
