C#で書いてみました。こんな感じです。

using System;
using System.IO;
using System.Net;
using System.Text;
 
namespace GoogleReaderDemo
{
    internal class Program
    {
        private static void Main(string[] args)
        {
            var sw = new StreamWriter("Feed.txt");
            Console.SetOut(sw);
 
            // Setup Request, uri, method, contenttype, contentlength and write the post data to requeststream.
            var res = (HttpWebRequest) WebRequest.Create(new Uri(@"https://www.google.com/accounts/ClientLogin"));
            res.Method = "POST";
            res.ContentType = "application/x-www-form-urlencoded";
 
            const string postData = "Email=yourname@gmail.com&Passwd=yourpassword&service=reader";
            byte[] bytes = Encoding.ASCII.GetBytes(postData);
            res.ContentLength = bytes.Length;
 
            string rspBody = "";
            using (Stream s = res.GetRequestStream())
            {
                s.Write(bytes, 0, bytes.Length);
                WebResponse rsp = res.GetResponse();
                var streamReader = new StreamReader(rsp.GetResponseStream());
                streamReader.ReadLine();
                streamReader.ReadLine();
                rspBody = streamReader.ReadToEnd();
            }
 
            // Request RSS with a name:value pair:  Authorization:GoogleLogin AUTH=..."
            res = (HttpWebRequest) WebRequest.Create(new Uri(@"http://www.google.com/reader/atom/"));
            res.Headers.Add("Authorization", "GoogleLogin " + rspBody);
            rspBody = new StreamReader(res.GetResponse().GetResponseStream()).ReadToEnd();
            Console.Write(rspBody);
 
            Console.ReadLine();
        }
    }
}

ATOM形式で返してくるので、どっかのParserがあればいいですね・・・自分書くのが面倒で・・・
Nugetで探したら、すぐ出てきました。

これでいけそう！
やってみました。

using System;
using System.IO;
using System.Net;
using System.Text;
using QDFeedParser;
 
namespace GoogleReaderDemo
{
    internal class Program
    {
        private static void Main(string[] args)
        {
            // Setup Request, uri, method, contenttype, contentlength and write the post data to requeststream.
            var res = (HttpWebRequest) WebRequest.Create(new Uri(@"https://www.google.com/accounts/ClientLogin"));
            res.Method = "POST";
            res.ContentType = "application/x-www-form-urlencoded";
 
            const string postData = "Email=youremail@gmail.com&Passwd=yourpassword&service=reader";
            byte[] bytes = Encoding.ASCII.GetBytes(postData);
            res.ContentLength = bytes.Length;
 
            string rspBody = "";
            using (Stream s = res.GetRequestStream())
            {
                s.Write(bytes, 0, bytes.Length);
                WebResponse rsp = res.GetResponse();
                var streamReader = new StreamReader(rsp.GetResponseStream());
                streamReader.ReadLine();
                streamReader.ReadLine();
                rspBody = streamReader.ReadToEnd();
            }
 
            // Request RSS with a name:value pair:  Authorization:GoogleLogin AUTH=..."
            res = (HttpWebRequest) WebRequest.Create(new Uri(@"http://www.google.com/reader/atom/"));
            res.Headers.Add("Authorization", "GoogleLogin " + rspBody);
            rspBody = new StreamReader(res.GetResponse().GetResponseStream()).ReadToEnd();
 
            File.WriteAllText(@"C:\Users\Z\Desktop\Feed.txt", rspBody);
            IFeedFactory factory = new FileSystemFeedFactory();
            IFeed feed = factory.CreateFeed(new Uri(@"C:\Users\Z\Desktop\Feed.txt"));
            foreach (BaseFeedItem i in feed.Items)
            {
                Console.WriteLine("_____________________________________________________");
                Console.WriteLine("Title : " + i.Title + Environment.NewLine); 
                Console.WriteLine("Link  : " + i.Link + Environment.NewLine); 
                Console.WriteLine("Date  : " + i.DatePublished);
            }
            Console.ReadLine();
        }
    }
