ServicePointManager.MaxServicePointIdleTime プロパティ

ServicePoint オブジェクトの最大アイドル時間を取得または設定します。

名前空間: System.Net
アセンブリ: System (system.dll 内)
構文

Visual Basic (宣言)

Public Shared Property MaxServicePointIdleTime
 As Integer

Visual Basic (使用法)

Dim value As Integer

value = ServicePointManager.MaxServicePointIdleTime

ServicePointManager.MaxServicePointIdleTime = value

public static int MaxServicePointIdleTime
 { get; set; }

C++

public:
static property int MaxServicePointIdleTime
 {
    int get ();
    void set (int value);
}

/** @property */
public static int get_MaxServicePointIdleTime
 ()

/** @property */
public static void set_MaxServicePointIdleTime
 (int value)

JScript

public static function get
 MaxServicePointIdleTime () : int

public static function set
 MaxServicePointIdleTime (value : int)

プロパティ値
ServicePoint オブジェクトのミリ秒単位の最大アイドル時間。既定値は 100,000 ミリ秒 (100 秒) です。

例外

例外の種類	条件
ArgumentOutOfRangeException	MaxServicePointIdleTime が Timeout.Infinite より小さい値か、Int32.MaxValue より大きい値です。

解説

MaxServicePointIdleTime プロパティは、ServicePoint オブジェクトの作成時に ServicePointManager オブジェクトが MaxIdleTime プロパティに割り当てる最大アイドル時間を設定します。この値への変更は、値が変更された後に初期化される ServicePoint オブジェクトにだけ影響します。

ServicePoint オブジェクトのアイドル時間が MaxIdleTime で指定した時間を超えた場合は、ガベージコレクションの対象となります。ServicePoint オブジェクトに関連付けられている接続の一覧が空の場合、ServicePoint オブジェクトはアイドル状態です。

使用例

このプロパティを設定するコード例を次に示します。

Visual Basic

' Set the maximum number of ServicePoint instances to maintain.
' Note that, if a ServicePoint instance for that host already 
' exists when your application requests a connection to
' an Internet resource, the ServicePointManager object
' returns this existing ServicePoint. If none exists 
' for that host, it creates a new ServicePoint instance.
ServicePointManager.MaxServicePoints = 4

' Set the maximum idle time of a ServicePoint instance to 10 seconds.
' After the idle time expires, the ServicePoint object is eligible for
' garbage collection and cannot be used by the ServicePointManager.
ServicePointManager.MaxServicePointIdleTime = 10000

// Set the maximum number of ServicePoint instances to 
// maintain. If a ServicePoint instance for that host already 
// exists when your application requests a connection to
// an Internet resource, the ServicePointManager object
// returns this existing ServicePoint instance. If none exists 
// for that host, it creates a new ServicePoint instance.
ServicePointManager.MaxServicePoints = 4;

// Set the maximum idle time of a ServicePoint instance to 10 seconds.
// After the idle time expires, the ServicePoint object is eligible
 for
// garbage collection and cannot be used by the ServicePointManager
 object.
ServicePointManager.MaxServicePointIdleTime = 10000;
