PageAsyncTask.State 屬性

public:
 property System::Object ^ State { System::Object ^ get(); };

public object State { get; }

member this.State : obj

Public ReadOnly Property State As Object

屬性值

代表 Object 任務的狀態。

範例

以下程式碼範例會建立三個非同步任務，並為它們 State 賦予獨特的屬性值。 這個例子是班級概述中另一個較大範例 PageAsyncTask 的一部分。

PageAsyncTask asyncTask1 = new PageAsyncTask(slowTask1.OnBegin, slowTask1.OnEnd, slowTask1.OnTimeout, "Async1", true);
PageAsyncTask asyncTask2 = new PageAsyncTask(slowTask2.OnBegin, slowTask2.OnEnd, slowTask2.OnTimeout, "Async2", true);
PageAsyncTask asyncTask3 = new PageAsyncTask(slowTask3.OnBegin, slowTask3.OnEnd, slowTask3.OnTimeout, "Async3", true);

// Register the asynchronous task.
Page.RegisterAsyncTask(asyncTask1);
Page.RegisterAsyncTask(asyncTask2);
Page.RegisterAsyncTask(asyncTask3);

Dim asyncTask1 As New PageAsyncTask(AddressOf slowTask1.OnBegin, AddressOf slowTask1.OnEnd, AddressOf slowTask1.OnTimeout, "Async1", True)
Dim asyncTask2 As New PageAsyncTask(AddressOf slowTask2.OnBegin, AddressOf slowTask2.OnEnd, AddressOf slowTask2.OnTimeout, "Async2", True)
Dim asyncTask3 As New PageAsyncTask(AddressOf slowTask3.OnBegin, AddressOf slowTask3.OnEnd, AddressOf slowTask3.OnTimeout, "Async3", True)

' Register the asynchronous task.
Page.RegisterAsyncTask(asyncTask1)
Page.RegisterAsyncTask(asyncTask2)
Page.RegisterAsyncTask(asyncTask3)

備註

該 State 屬性在建構子中設定，且在執行非同步任務時無法更改。 你可以透過為非 State 同步任務的屬性分配獨特的字串值來區分這些任務。
