// to associates a stored procedure which user defined in the database.
// Must write it before func.
[global::System.Data.Linq.Mapping.FunctionAttribute(Name ="stored procedure name")]
// Undertake on a code, we make a func. let user to access the stored procedure.
// When SP exist input variables, you must use "Linq.Mapping.ParameterAttribute" to
// select the variable in DB and use "System.Nullable" to set
// what variable you wnat to assign in code.

So........We know "as" is a powerful method that perform certain types of conversions between compatible reference types. for example:
 
// ...... //
Array[] = dataTable;
// ....do something for dataTable.//
const string = "ALamTest";
Session[ALamTest] = dataTable;

//....do another something...//

Array[] getTable = Session[AlamTest] as Array[]

This is a new Characteristic in C#3.0

// Create a new dictionary of strings, with string keys.

// The indexer can be used to change the value associated
// with a key.
openWith["rtf"] = "Alamword.exe";
Console.WriteLine("For key = \"rtf\", value = {0}.",

// The Add method throws an exception if the new key is

catch (ArgumentException)

// not in the dictionary.
try
{
Console.WriteLine("For key = \"tif\", value = {0}.",
openWith["tif"]);
}
catch (KeyNotFoundException)
{

恩如標題講的，最近解一個Bug挺有趣的。當Bug解完以後，在我自己的本機端測試是正常的，但是放到測試機上的時候卻出問題了......./冏\ !!!!
最後發現是有兩個問題存在：
<1> 測試機上的Cache是上一個版本的，我必須要Uninstall系統，在build起來以後才會把Cache取消掉。
<2> 測試人員從DB中直接修改資料，而後台的DropList是抓取Cache中的資料，所以就沒同步更新到了，然後在真正要撈資料的時候就會出錯了.....。

最近在解Bug的時候遇到了這個問題。去查了一些相關的文章以後發現，這是.Net Framework 4.0以後的新功能，它幫助你在跟Server請求任何的Request的時候，都會自動地做請求驗證(ValidationRequest)。
雖然我碰的是ASP.net，但是經由資料查詢以後只要是使用到.net framework 4.0以上的版本都會使用到這個功能，不過其實我還不太懂所以就不要亂寫好了XD。但是可以得知的是利用Asp.net撰寫網站的時候，他會預設這個功能就是了。
解決的方法也蠻簡單的：
