ServicePoint.IdleSince 屬性

定義

命名空間:

System.Net

組件:

System.Net.ServicePoint.dll

來源:

ServicePoint.cs

取得 ServicePoint 物件上次連接到主機的日期和時間。

public:
 property DateTime IdleSince { DateTime get(); };

public DateTime IdleSince { get; }

member this.IdleSince : DateTime

Public ReadOnly Property IdleSince As DateTime

屬性值

DateTime

DateTime 物件，其中包含上次連接 ServicePoint 物件的日期和時間。

範例

下列程式代碼範例會使用 IdleSince 屬性來設定和擷取 ServicePoint 物件上次連接到主機的日期和時間。

// Display the date and time that the ServicePoint was last 
// connected to a host.
Console::WriteLine( "IdleSince = {0}", sp->IdleSince );

// Display the maximum length of time that the ServicePoint instance  
// is allowed to maintain an idle connection to an Internet  
// resource before it is recycled for use in another connection.
Console::WriteLine( "MaxIdleTime = {0}", sp->MaxIdleTime );

// Display the date and time that the ServicePoint was last
// connected to a host.
Console.WriteLine("IdleSince = " + sp.IdleSince.ToString());

// Display the maximum length of time that the ServicePoint instance
// is allowed to maintain an idle connection to an Internet
// resource before it is recycled for use in another connection.
Console.WriteLine("MaxIdleTime = " + sp.MaxIdleTime);

' Display the date and time that the ServicePoint was last 
' connected to a host.
Console.WriteLine(("IdleSince = " + sp.IdleSince.ToString()))


' Display the maximum length of time that the ServicePoint instance 
' is allowed to maintain an idle connection to an Internet  
' resource before it is recycled for use in another connection.
Console.WriteLine(("MaxIdleTime = " + sp.MaxIdleTime.ToString()))

備註

謹慎

WebRequest、HttpWebRequest、ServicePoint和 WebClient 已經過時，您不應該將它們用於新的開發。 請改用 HttpClient。

IdleSince 屬性會記錄服務點與主機中斷連線的最後日期和時間。 當目前時間與 IdleSince 之間的差異超過 MaxIdleTime的值時，ServicePoint 物件可用來回收至另一個連接。
