定義
重要
部分資訊涉及發行前產品,在發行之前可能會有大幅修改。 Microsoft 對此處提供的資訊,不做任何明確或隱含的瑕疵擔保。
取得或設定值,表示 EventLog 是否接收 EntryWritten 事件通知。
public:
property bool EnableRaisingEvents { bool get(); void set(bool value); };
[System.ComponentModel.Browsable(false)]
public bool EnableRaisingEvents { get; set; }
[<System.ComponentModel.Browsable(false)>]
member this.EnableRaisingEvents : bool with get, set
Public Property EnableRaisingEvents As Boolean
屬性值
如果 EventLog 在項目寫入到記錄檔時接收通知,則為 true
,否則為 false
。
- 屬性
例外狀況
事件記錄位於遠端電腦上。
範例
下列範例會處理 EntryWritten 事件。
#using <System.dll>
using namespace System;
using namespace System::Diagnostics;
using namespace System::Threading;
ref class MySample
{
public:
static void MyOnEntryWritten( Object^ /*source*/, EntryWrittenEventArgs^ e )
{
Console::WriteLine( "Written: {0}", e->Entry->Message );
}
};
int main()
{
EventLog^ myNewLog = gcnew EventLog;
myNewLog->Log = "MyCustomLog";
myNewLog->EntryWritten += gcnew EntryWrittenEventHandler( MySample::MyOnEntryWritten );
myNewLog->EnableRaisingEvents = true;
Console::WriteLine( "Press \'q\' to quit." );
// Wait for the EntryWrittenEvent or a quit command.
while ( Console::Read() != 'q' )
{
// Wait.
}
}
using System;
using System.Diagnostics;
using System.Threading;
class MySample{
public static void Main(){
EventLog myNewLog = new EventLog();
myNewLog.Log = "MyCustomLog";
myNewLog.EntryWritten += new EntryWrittenEventHandler(MyOnEntryWritten);
myNewLog.EnableRaisingEvents = true;
Console.WriteLine("Press \'q\' to quit.");
// Wait for the EntryWrittenEvent or a quit command.
while(Console.Read() != 'q'){
// Wait.
}
}
public static void MyOnEntryWritten(Object source, EntryWrittenEventArgs e){
Console.WriteLine("Written: " + e.Entry.Message);
}
}
Option Strict
Option Explicit
Imports System.Diagnostics
Imports System.Threading
Class MySample
Public Shared Sub Main()
Dim myNewLog As New EventLog()
myNewLog.Log = "MyCustomLog"
AddHandler myNewLog.EntryWritten, AddressOf MyOnEntryWritten
myNewLog.EnableRaisingEvents = True
Console.WriteLine("Press 'q' to quit.")
' Wait for the EntryWrittenEvent or a quit command.
While Char.ToLower(Convert.ToChar(Console.Read()))<>"q"
' Wait.
End While
End Sub
Public Shared Sub MyOnEntryWritten(source As Object, e As EntryWrittenEventArgs)
Console.WriteLine(("Written: " + e.Entry.Message))
End Sub
End Class
備註
屬性 EnableRaisingEvents 會決定 當專案寫入記錄檔時,是否 EventLog 引發事件。 當 屬性為 true
時,接收 EntryWritten 事件的元件會在每次將專案寫入屬性中指定的 Log 記錄檔時收到通知。 如果 為 EnableRaisingEventsfalse
,則不會引發任何事件。
注意
只有在本機計算機上寫入專案時,才可以接收事件通知。 您無法收到遠端電腦上寫入專案的通知。
