EntryWrittenEventArgs コンストラクタ (EventLogEntry)

指定したイベント ログ エントリを使用して、EntryWrittenEventArgs クラスの新しいインスタンスを初期化します。

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

構文

'宣言
Public Sub New ( _
    entry As EventLogEntry _
)
'使用
Dim entry As EventLogEntry

Dim instance As New EntryWrittenEventArgs(entry)

public EntryWrittenEventArgs (
    EventLogEntry entry
)

public:
EntryWrittenEventArgs (
    EventLogEntry^ entry
)

public EntryWrittenEventArgs (
    EventLogEntry entry
)

public function EntryWrittenEventArgs (
    entry : EventLogEntry
)

パラメータ

• entry
  書き込まれたエントリを表す EventLogEntry。

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。
