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

'宣言
Public Class EntryWrittenEventArgs
    Inherits EventArgs
'使用
Dim instance As EntryWrittenEventArgs

public class EntryWrittenEventArgs : EventArgs

public ref class EntryWrittenEventArgs : public EventArgs

public class EntryWrittenEventArgs extends EventArgs

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。
