示例

下面的代码示例演示如何 PartialCachingAttribute(Int32, String, String, String) 将构造函数应用于用户控件。 在此示例中，构造函数用于指示可以缓存用户控件，并指定缓存项依赖的参数。

// Set the PartialCachingAttribute.Duration property to
// 20 seconds and the PartialCachingAttribute.VaryByParams
// property to ctlSelect.country, the full name of the form 
// POST parameter generated by the country DropDownList control.
[PartialCaching(20, "ctlSelect.country", null, null)]
public partial class ctlSelect : UserControl

' Set the PartialCachingAttribute.Duration property to
' 20 seconds and the PartialCachingAttribute.VaryByParams
' property to ctlSelect.country, the full name of the form 
' POST parameter generated by the country DropDownList control.
<PartialCaching(20, "ctlSelect.country", Nothing, Nothing)> _
