EntryWrittenEventArgs クラス

EntryWritten イベントのデータを提供します。

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

Visual Basic (宣言)

Public Class EntryWrittenEventArgs
    Inherits EventArgs

Visual Basic (使用法)

Dim instance As EntryWrittenEventArgs

public class EntryWrittenEventArgs : EventArgs

C++

public ref class EntryWrittenEventArgs : public
 EventArgs

public class EntryWrittenEventArgs extends
 EventArgs

JScript

public class EntryWrittenEventArgs extends
 EventArgs

使用例

EntryWrittenEventArgs コンストラクタの例を次に示します。これは、カスタム EventLog オブジェクトを作成して、エントリを書き込みます。次に、カスタム EventLog 内の最初のエントリを使用して EntryWrittenEventArgs オブジェクトを作成します。このオブジェクトは、メッセージを通知するときに使用します。
