繼
ASP.NET 取得 GMAIL 的聯絡人清單 (Get Google Contacts List)
以及
ASP.NET 取得 Yahoo! 的聯絡人清單 (Get Yahoo Mail Contacts)
兩篇文章之後，這一篇則是針對大家常用的Windows Live! Messenger取得所有連絡人的資訊。
其實跟Google及Yahoo都是類似的做法，主要都是使用HTTP protocol中的Request及Response取得瀏覽器以及伺服器往來的資訊。最後取得連絡人的資料後(通常是csv，或是通用xml格式)。

而這次要取得Windows Live Messenger連絡人的方式，老實說比以往還要複雜一些，因為要自己包裝SOAP envelope作為server response file(srf檔)，最後再取得伺服器的回傳值(ticket)。這邊有個小問題跟Yahoo是一樣的，回傳的ticket開頭最前面的2個字元是 “t=”，與當初取得Yahoo!聯絡人清單類似，只是Yahoo所得到的token前面有 “Y=” 兩個字元必須移除罷了。感謝SourceForge上讓我找到了OpenContacts.NET，否則我大概要多花一倍以上的時間去研讀各家的API。以下直接把取得ticket及擷取MSN連絡人的方法直接貼出來，這部份我有修改了一些OpenContacts.NET的內容，不過內容上並沒有什麼差異，主要是差在輸出的格式罷了 : )
