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

Visual Basic (宣言)

Public Sub New ( _
    entry As EventLogEntry _
)

Visual Basic (使用法)

Dim entry As EventLogEntry

Dim instance As New EntryWrittenEventArgs(entry)

public EntryWrittenEventArgs (
    EventLogEntry entry
)

C++

public:
EntryWrittenEventArgs (
    EventLogEntry^ entry
)

public EntryWrittenEventArgs (
    EventLogEntry entry
)

JScript

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。
