ISessionStateItemCollection.Dirty 屬性


取得或設定值,這個值表示集合是否標示為已變更。Gets or sets a value indicating whether the collection has been marked as changed.

 property bool Dirty { bool get(); void set(bool value); };
public bool Dirty { get; set; }
member this.Dirty : bool with get, set
Public Property Dirty As Boolean


如果 SessionStateItemCollection 內容已變更,則為 true,否則為 falsetrue if the SessionStateItemCollection contents have been changed; otherwise, false.


下列程式碼範例顯示Dirty屬性的執行。The following code example shows an implementation of the Dirty property. 如需完整的ISessionStateItemCollection介面執行範例, 請參閱ISessionStateItemCollection針對介面總覽提供的範例。For an example of a complete implementation of the ISessionStateItemCollection interface, see the example provided for the ISessionStateItemCollection interface overview.

private bool pDirty = false;

public bool Dirty
  get { return pDirty; }
  set { pDirty = value; }
Private pDirty As Boolean = False

Public Property Dirty As Boolean Implements ISessionStateItemCollection.Dirty    
    Return pDirty
  End Get
    pDirty = value
  End Set
End Property


會使用Dirty ISessionStateItemCollection屬性來判斷是否已修改執行中的值。 SessionStateModuleThe Dirty property is used by the SessionStateModule to determine whether the values in an ISessionStateItemCollection implementation have been modified.

在執行ISessionStateItemCollection介面時, 您應該將Dirty Dirty屬性初始化為false , 並在RemoveRemoveAttrue Clear的執行中將屬性設定為。方法。In implementing the ISessionStateItemCollection interface, you should initialize the Dirty property as false and set the Dirty property to true in the implementations of the Remove, RemoveAt, or Clear methods.
