搜尋指定電腦上的所有事件記錄檔，並建立含有清單的 EventLog 物件陣列。
public:
static cli::array <System::Diagnostics::EventLog ^> ^ GetEventLogs(System::String ^ machineName);public static System.Diagnostics.EventLog[] GetEventLogs (string machineName);static member GetEventLogs : string -> System.Diagnostics.EventLog[]Public Shared Function GetEventLogs (machineName As String) As EventLog()參數
- machineName
- String
要在其上搜尋事件記錄檔的電腦。
傳回
EventLog[]
表示指定電腦上記錄檔的類型 EventLog 的陣列。
例外狀況
machineName 參數是無效的電腦名稱。
範例
下列範例會取得電腦 「myServer」 上的記錄清單。 然後，它會輸出每個記錄檔的名稱。
#using <System.dll>
using namespace System;
using namespace System::Diagnostics;
using namespace System::Threading;
int main()
{
array<EventLog^>^remoteEventLogs;
remoteEventLogs = EventLog::GetEventLogs( "myServer" );
Console::WriteLine( "Number of logs on computer: {0}", remoteEventLogs->Length );
System::Collections::IEnumerator^ myEnum = remoteEventLogs->GetEnumerator();
while ( myEnum->MoveNext() )
{
EventLog^ log = safe_cast<EventLog^>(myEnum->Current);
Console::WriteLine( "Log: {0}", log->Log );
}
}
using System;
using System.Diagnostics;
class MySample
{
public static void Main()
{
EventLog[] remoteEventLogs;
remoteEventLogs = EventLog.GetEventLogs("myServer");
Console.WriteLine("Number of logs on computer: " + remoteEventLogs.Length);
foreach (EventLog log in remoteEventLogs)
{
Console.WriteLine("Log: " + log.Log);
}
}
}
Imports System.Diagnostics
Imports System.Threading
Class MySample
Public Shared Sub Main()
Dim remoteEventLogs() As EventLog
remoteEventLogs = EventLog.GetEventLogs("myServer")
Console.WriteLine(("Number of logs on computer: " & remoteEventLogs.Length))
Dim log As EventLog
For Each log In remoteEventLogs
Console.WriteLine(("Log: " & log.Log))
Next log
End Sub
End Class
備註
物件的陣列 EventLog 是在呼叫 GetEventLogs 時，參數所 machineName 指定電腦上所有事件記錄檔的快照集。 這不是動態集合，因此不會即時反映刪除或建立記錄。 您應該先確認陣列中的記錄檔存在，再讀取或寫入陣列。 陣列通常至少包含三個記錄：應用程式、系統和安全性。 如果您在指定的電腦上建立自訂記錄，它們也會出現在陣列中。
GetEventLogs 是方法 static ，因此可以在類別本身上 EventLog 呼叫。 不需要建立 物件的實例 EventLog ，即可呼叫 方法。
若要擷取事件記錄檔的清單，您必須具有適當的登入權利。 這些許可權與呼叫 Exists 和 SourceExists 所需的許可權相同。
