範例

下列程式碼範例示範如何將建 PartialCachingAttribute(Int32, String, String, String) 構函式套用至使用者控制項。 在此範例中，建構函式用來指出可以快取使用者控制項、將快取持續時間指定為 20 秒，以及指定名為 state 的控制項，而使用者控制項輸出將會有所不同。

// Set the PartialCachingAttribute.Duration property to
// 20 seconds and the PartialCachingAttribute.VaryByControls
// property to the ID of the server control to vary the output by.
// In this case, it is state, the ID assigned to a DropDownList
// server control.
[PartialCaching(20, null, "state", null)]

' Set the PartialCachingAttribute.Duration property to
' 20 seconds and the PartialCachingAttribute.VaryByControls
' property to the ID of the server control to vary the output by.
' In this case, it is state, the ID assigned to a DropDownList
' server control.
