EventLog.EnableRaisingEvents 属性

定义

命名空间:

System.Diagnostics

程序集:

System.Diagnostics.EventLog.dll

包:

System.Diagnostics.EventLog v8.0.0

Source:

EventLog.cs

获取或设置一个值，用以指示 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

属性值

Boolean

如果 EventLog 在有项写入日志时接收通知，则为 true；否则为 false。

属性

BrowsableAttribute

例外

InvalidOperationException

事件日志位于远程计算机上。

示例

以下示例处理 事件 EntryWritten 。

#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

注解

属性 EnableRaisingEvents 确定在将条目写入日志时是否 EventLog 引发事件。 当 属性为 true时，每当将条目写入 属性中指定的Log日志时，接收EntryWritten事件的组件将收到通知。 如果 EnableRaisingEvents 为 false，则不引发任何事件。

注意

仅当在本地计算机上写入条目时，才能接收事件通知。 无法接收远程计算机上写入的条目的通知。
