Setting MaxItemsInObjectGraph for WCF

WCF傳輸大資料量的問題，現在網上討論的很多，大多是設定maxReceivedMessageSize="2147483647" maxBufferPoolSize="2147483647" maxBufferSize="2147483647"。

這些我也都設定了，但是今天在調試WCF的時候，當我用一個帳號進行操作一切OK。但當我用另外一個帳號操作的時候卻報了錯誤

“對象圖中可以序列化或還原序列化的項目數目上限為“65536”，請更改對象圖或增加 MaxItemsInObjectGraph 的配額”。

最後我一查資料庫才發現先前帳號的資料只有幾百條，而另一個帳號有1W多條，肯定是資料爆了。

下面就來說下如果在服務端和用戶端設定MaxItemsInObjectGraph 

WCF 服務端設定檔

這樣伺服器端和用戶端配置後，就可以提高最大傳輸量了。
