以後在開發中需要注意的東西

1、枚舉類型要有預設值。

　　枚舉類型一般情況下要多出來一項用於標明該值為空白或者沒有賦值。

　　如果沒有賦值，在WCF傳遞的時候會出現莫名其秒的錯誤提示。

　　我所見到的有：“An existing connection was forcibly closed by the remote host”、

　　“System.Collections.ListDictionaryInternal \r\n Data:An error occurred while receiving the HTTP response to SVC PATH. This could be due to the service endpoint binding not using the HTTP protocol. This could also be due to an HTTP request context being aborted by the server (possibly due to the service shutting down). See server logs for more details.”

　　如果你在使用WCF的時候遇到此類提示，請先檢查傳遞的資料中是不是包含有枚舉類型而沒有賦值的。
