PartialCachingAttribute 构造函数

public:
 PartialCachingAttribute(int duration);

public PartialCachingAttribute(int duration);

new System.Web.UI.PartialCachingAttribute : int -> System.Web.UI.PartialCachingAttribute

Public Sub New (duration As Integer)

参数

示例

下面的代码示例演示如何将 PartialCachingAttribute(Int32) 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持续时间。 该代码示例是 PartialCachingAttribute 类中的一个较大示例的一部分。

// Set the PartialCachingAttribute.Duration property to 20 seconds.
[PartialCaching(20)]
public partial class ctlMine : UserControl

' Set the PartialCachingAttribute.Duration property to 20 seconds.
<PartialCaching(20)> _
Partial Class ctlMine
    Inherits UserControl

public:
 PartialCachingAttribute(int duration, System::String ^ varyByParams, System::String ^ varyByControls, System::String ^ varyByCustom);

public PartialCachingAttribute(int duration, string varyByParams, string varyByControls, string varyByCustom);

new System.Web.UI.PartialCachingAttribute : int * string * string * string -> System.Web.UI.PartialCachingAttribute

Public Sub New (duration As Integer, varyByParams As String, varyByControls As String, varyByCustom As String)

参数

示例

下面的代码示例演示如何将 PartialCachingAttribute(Int32, String, String, String) 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，将缓存持续时间指定为 20 秒，并指定一个名为 state 用户控件输出的控件。

// 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.
<PartialCaching(20, Nothing, "state", Nothing)> _
Public Class ctlSelect
    Inherits UserControl

public:
 PartialCachingAttribute(int duration, System::String ^ varyByParams, System::String ^ varyByControls, System::String ^ varyByCustom, bool shared);

public PartialCachingAttribute(int duration, string varyByParams, string varyByControls, string varyByCustom, bool shared);

new System.Web.UI.PartialCachingAttribute : int * string * string * string * bool -> System.Web.UI.PartialCachingAttribute

Public Sub New (duration As Integer, varyByParams As String, varyByControls As String, varyByCustom As String, shared As Boolean)

参数

public:
 PartialCachingAttribute(int duration, System::String ^ varyByParams, System::String ^ varyByControls, System::String ^ varyByCustom, System::String ^ sqlDependency, bool shared);

public PartialCachingAttribute(int duration, string varyByParams, string varyByControls, string varyByCustom, string sqlDependency, bool shared);

new System.Web.UI.PartialCachingAttribute : int * string * string * string * string * bool -> System.Web.UI.PartialCachingAttribute

Public Sub New (duration As Integer, varyByParams As String, varyByControls As String, varyByCustom As String, sqlDependency As String, shared As Boolean)
