EntryWrittenEventArgs()
初始化 EntryWrittenEventArgs 類別的新執行個體。
public:
EntryWrittenEventArgs();public EntryWrittenEventArgs();Public Sub New ()範例
以下範例展示了該 EntryWrittenEventArgs 建構子。 它會建立一個自訂 EventLog 物件並寫入一個項目。 接著它會利用自訂EntryWrittenEventArgs的第一個項目建立EventLog一個物件。 此物件用於通知訊息。
using System;
using System.Diagnostics;
class MySample
{
public static void Main()
{
try
{
EventLog myNewLog = new EventLog();
myNewLog.Log = "MyNewLog";
myNewLog.Source = "MySource";
// Create the source if it does not exist already.
if (!EventLog.SourceExists("MySource"))
{
// An event log source should not be created and immediately used.
// There is a latency time to enable the source, it should be created
// prior to executing the application that uses the source.
// Execute this sample a second time to use the new source.
EventLog.CreateEventSource("MySource", "MyNewLog");
Console.WriteLine("CreatingEventSource");
Console.WriteLine("Exiting, execute the application a second time to use the source.");
// The source is created. Exit the application to allow it to be registered.
return;
}
// Write an entry to the EventLog.
myNewLog.WriteEntry("The Latest entry in the Event Log");
int myEntries = myNewLog.Entries.Count;
EventLogEntry entry = myNewLog.Entries[myEntries - 1];
EntryWrittenEventArgs myEntryEventArgs =
new EntryWrittenEventArgs();
MyOnEntry(myNewLog, myEntryEventArgs);
}
catch (Exception e)
{
Console.WriteLine("Exception Raised" + e.Message);
}
}
protected static void MyOnEntry(Object source, EntryWrittenEventArgs e)
{
if (e.Entry == null)
Console.WriteLine("A new entry is written in MyNewLog.");
}
}
Imports System.Diagnostics
Class MySample
Public Shared Sub Main()
Try
Dim myNewLog As New EventLog()
myNewLog.Log = "MyNewLog"
myNewLog.Source = "MySource"
' Create the source if it does not exist already.
If Not EventLog.SourceExists("MySource") Then
EventLog.CreateEventSource("MySource", "MyNewLog")
Console.WriteLine("CreatingEventSource")
End If
' Write an entry to the EventLog.
myNewLog.WriteEntry("The Latest entry in the Event Log")
Dim myEntryEventArgs As EntryWrittenEventArgs = _
New EntryWrittenEventArgs()
MyOnEntry(myNewLog, myEntryEventArgs)
Catch e As Exception
Console.WriteLine("Exception Raised" + e.Message)
End Try
End Sub
Protected Shared Sub MyOnEntry(ByVal source As Object, _
ByVal e As EntryWrittenEventArgs)
If e.Entry Is Nothing Then
Console.WriteLine("A new entry is written in MyNewLog.")

適用於
EntryWrittenEventArgs(EventLogEntry)
初始化一個新的類別實例 EntryWrittenEventArgs ，並以指定的事件日誌條目。
public:
EntryWrittenEventArgs(System::Diagnostics::EventLogEntry ^ entry);public EntryWrittenEventArgs(System.Diagnostics.EventLogEntry? entry);public EntryWrittenEventArgs(System.Diagnostics.EventLogEntry entry);new System.Diagnostics.EntryWrittenEventArgs : System.Diagnostics.EventLogEntry -> System.Diagnostics.EntryWrittenEventArgsPublic Sub New (entry As EventLogEntry)參數
- entry
- EventLogEntry
代表 EventLogEntry 所寫的條目。
