Twitter タイムラインをストリームで引っこ抜く

.NET Twitter C#

前回同様にTwitterizer経由で突っ込んだ。
Stream なので、継続的に拾えるようだ。

using Twitterizer;
using Twitterizer.Streaming;

namespace TwitterTest
{
    public class TweetLine 
    {
        public String User { get; set; }
        public DateTime Time { get; set; }
        public String Message { get; set; }
    }

    public class TwitterEvent : EventArgs
    {
        public TweetLine Value;

        public TwitterEvent(TweetLine arg)
        {
            this.Value = arg;
        }
    }

    public class TwitterAccessor : IDisposable
    {
        const string CONSUMER_KEY = "key";
        const string CONSUMER_SECRET = "secret key";
