Timer コンストラクタ (Double)

Timer クラスの新しいインスタンスを初期化し、Interval プロパティを指定した間隔に設定します。

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

構文

'宣言
Public Sub New ( _
    interval As Double _
)
'使用
Dim interval As Double

Dim instance As New Timer(interval)

public Timer (
    double interval
)

public:
Timer (
    double interval
)

public Timer (
    double interval
)

public function Timer (
    interval : double
)

適用できません。

パラメータ

• interval
  ミリ秒単位でのイベントの発生間隔。

例外

使用例

10 秒経過すると、コンソールに "Hello World!" と表示する Timer を作成する例を次に示します。

この例では、System.Timers 名前空間を使用します。

' From command line, compile with /r:System.dll
Imports System
Imports System.Timers

Public Class Timer2
    
    Public Shared Sub Main()
        ' Normally, the timer is declared at the class level, so
        ' that it doesn't go out of scope when the method ends.
        ' In this example, the timer is needed only while Main 
        ' is executing. However, KeepAlive must be used at the
        ' end of Main, to prevent the JIT compiler from allowing 
        ' aggressive garbage collection to occur before Main 
        ' ends.
        '
