ServicePointManager.MaxServicePoints プロパティ

.NET Framework クラス ライブラリ リファレンス

ServicePointManager.MaxServicePoints プロパティ

同時に維持される ServicePoint オブジェクトの最大数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 MaxServicePoints
 As Integer

Visual Basic (使用法)

Dim value As Integer

value = ServicePointManager.MaxServicePoints

ServicePointManager.MaxServicePoints = value

C#

public static int MaxServicePoints
 { get; set; }

C++

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

J#

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

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

JScript

public static function get
 MaxServicePoints () : int

public static function set
 MaxServicePoints (value : int)

プロパティ値
維持される ServicePoint オブジェクトの最大数。既定値は 0 です。これは ServicePoint オブジェクトの数に制限がないことを示します。

例外

例外の種類	条件
ArgumentOutOfRangeException	MaxServicePoints が 0 未満か、または Int32.MaxValue を超えています。

解説

MaxServicePoints プロパティを現在の ServicePoint オブジェクト数未満に設定すると、ServicePointManager はアイドル時間が最も長い ServicePoint オブジェクトを削除します。アクティブな接続を持つ ServicePoint オブジェクトの数が MaxServicePoints の値を超える場合、ServicePointManager オブジェクトはアイドル状態になった ServicePoint オブジェクトを削除します。

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

C#

// 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;

ServicePointManager::MaxServicePoints = 4;

// Set the maximum idle time of a ServicePoint instance to 10 seconds.

ServicePointManager.set_MaxServicePoints(4);
