最近興趣使然嘗試了一下使用DotNet技術(shù)實現(xiàn)新浪微博PC客戶端，幾天時間，目前實現(xiàn)登錄、微博列表、發(fā)布純文本微博功能，新浪API調(diào)用基本沒什么難度，在微博列表形式處理上著實讓我煩躁了一陣子，Windows Form使用不多，這次開發(fā)也感覺有些捉襟見肘。

?

環(huán)境：

操作系統(tǒng)：Windows 7 Ultimate

集成開發(fā)環(huán)境：Visual Studio 2010 Ultimate

.NET Framework：3.5

?

先看一下截圖：

1、登錄界面

?

2、 登錄

?

3、第一次運(yùn)行主界面加載

?

4、主頁面

?

5、翻頁?

?

?6）如果博文中有圖，點(diǎn)擊小圖可以查看大圖

?

新浪微博API返回的數(shù)據(jù)類型有兩種：XML和JSON。在登錄時，我直接用DataSet讀的XML數(shù)據(jù)存儲到一個靜態(tài)用戶信息類中；而博客列表數(shù)據(jù)我讀取的是JSON格式的數(shù)據(jù)，并將JSON格式的數(shù)據(jù)反序列化為泛型對象（類）集合，這里的類是嵌套類。?

?

然后繪制列表，顯示數(shù)據(jù)的控件全部是動態(tài)添加的，這里最煩的是位置，可能也是這個原因?qū)е旅宽?0條數(shù)據(jù)加載比較慢（接口默認(rèn)一頁返回20條），最快也要2秒，經(jīng)常要4-6秒，后面提供下載，大家可以試試。另外，影響速度的原因可能還有：1）網(wǎng)速；2）輸出圖片，有的是直接輸出大圖，在回復(fù)的源微博中如果有圖片，總是獲取不到縮略圖，只好依次判斷小圖、中圖、大圖，先有哪個輸出哪個。?用Label顯示文本行間距沒法調(diào)，只好做了個自定義控件，主要是根據(jù)字體大小了增大行距。?

?

界面雖然使用皮膚（ssk），比Window Form原始的界面好看的多，但是比起Adobe的那個AIR還是有差距，或許可以嘗試使用WPF。?

?

后續(xù)要實現(xiàn)的功能（還沒全部看API，有的功能不一定提供API）：

1）轉(zhuǎn)發(fā)、收藏、回復(fù)

2）發(fā)帖可以使用表情、可以上傳圖片

3）關(guān)注、粉絲列表

4）查看自己微博、他人微博列表

5）個人的一些配置信息

6）主界面左邊想放新浪微博登錄后，個人首頁右邊的內(nèi)容?

... ...

工作量還挺大:(的。?

?

目前經(jīng)過處理，程序運(yùn)行后占用的內(nèi)存在4M-25M這樣的一個范圍 ，如果不處理會一直攀升，100M、200M、... ... 。

在翻頁時，加載顯示瞬時CPU占用率能夠達(dá)到30%左右，一般比較低，5%以下。

滾屏?xí)r，CPU占用率一般18%以下，都是瞬時的。?

大家看到的數(shù)據(jù)異步加載使用了多線程，主要是使用了BackgroundWorker。

?

除了上面的問題，在滾屏?xí)r，滾動的內(nèi)容有點(diǎn)閃，還沒找到好的解決辦法。

?

歡迎有興趣的人一起討論，提寶貴意見。有經(jīng)驗的人做個指導(dǎo):)。?

感謝博客園的這篇文章，參考價值很大：http://www.cnblogs.com/cmt/archive/2010/05/13/1733904.html?

注：AppKey以內(nèi)置，是我申請的，每IP每用戶一小時內(nèi)限調(diào)用350次API。

PS：別拿來干壞事... ...?
