<%# Eval("SDate", "{0:yyyy/MM/dd}") %>
// 0: 表示定義整個括號裡面的第 0 個變數要採用此日期格式。

// 以下為兩個變數的範例。
string s = String.Format("At {0}, the temperature is {1}°C.",
                         DateTime.Now, 20.4);
Console.WriteLine(s);
// Output similar to: 'At 4/10/2015 9:29:41 AM, the temperature is 20.4°C.'

//MVC3開始，新增Razer語法，不同於先前的<%...%>括號語法，使用At Sgin(@)敘述程式碼片段。

//在Razer檢視中，使用@*...*@進行程式註解。

//在程式碼中，要輸出內容，要加@或@(...)
//在html標籤中，要輸出內容，要加@
//在程式碼中，要輸出純文字，要加@:

@if(true)
{
    String strPrint = "這是測試輸出文字";
    @strPrint<br/>
    <span>strPring</span><br />
    <span>@strPrint</span><br />
}

@{string strl = "測試";}
@(strl)輸出文字<br />

@{ string strHtml1 = "<ul><li>項目一</li></ul>";}
@Html.Raw(strHtml1)<br />

//在測試Controller與View時，如果因為設中斷點導致網頁顯示不完整而無法進行測試，
//可以試著點選"跳離函式(Shift+F11)"，讓頁面完整顯示，以進行測試。

//先於Model設計好欄位變數等，
//再於Controller設定執行時，透過剛設計的Model樣板，進行各個變數的處理(遞交資料)
//如從網頁欄位A讀取資料到變數X，再把X送到網頁的欄位B
//最後於View設計各欄位的顯示情形
