網站開發,善用 Cached DataTable 可以使網站效能倍增,不必一直去資料庫抓資料。
但是使用 Cached DataTable 有一個地方要注意
就是他是 Shared 物件,表示同時有好幾個頁面都可以存取他
例如A網頁將資料抓出,然後變更裡面的DataRow資料,
另一個B網頁也會跟著變更
由於 Cached DataTable 在 Set DataRow Value 時
可能 Critical Section 沒有處理好,若真的同時多個thread 操作
會出現 Exception
(System.ArgumentOutOfRangeException: 索引超出範圍。必須為非負數且小於集合的大小。)
建議:
'這是 UNT FixPage 物件抓取單一資料的範例
Shared Function GetSpecialPage2FromCachedDT(ByVal Key As Int32) As DB.SpecialPage2
Dim DT As DataTable = GetAllDataFromBaseTableWithCache()
Dim Row As DataRow = DT.Rows.Find(Key)
If Row IsNot Nothing Then
'避免每個thread都共用table 寫入資料會出現問題
Dim newDT As DataTable = DT.Clone()
newDT.ImportRow(Row)
Return New SpecialPage2(newDT.Rows(0))
Else
Return Nothing
End If
End Function
