DeleteEventSource(String)

Source:: EventLog.cs

Source:: EventLog.cs

Source:: EventLog.cs

从本地计算机的事件日志中移除事件源注册。

public:
 static void DeleteEventSource(System::String ^ source);

public static void DeleteEventSource (string source);

static member DeleteEventSource : string -> unit

Public Shared Sub DeleteEventSource (source As String)

参数

source: String

应用程序在事件日志系统中用来注册的名称。

例外

ArgumentException

本地计算机的注册表中不存在 source 参数。

- 或 -

您对事件日志的注册表项没有写访问权。

示例

以下示例从本地计算机中删除源。该示例从其源中确定日志，然后删除该日志。

注意

多个源可能会写入事件日志。删除自定义日志之前，请确保没有其他源写入该日志。

#using <System.dll>

      logName = EventLog::LogNameFromSourceName( "MySource", "." );
      // Make sure the source is in the log we believe it to be in
      if (logName != "MyLog")
          return -1;
      // Delete the source and the log.
      EventLog::DeleteEventSource( "MySource" );
      EventLog::Delete( logName );
      Console::WriteLine( "{0} deleted.", logName );
   }
   else
        {
            // Create the event source to make next try successful.

            // Find the log associated with this source.
            logName = EventLog.LogNameFromSourceName("MySource", ".");
            // Make sure the source is in the log we believe it to be in.
            if (logName != "MyLog")
                return;
            // Delete the source and the log.
            EventLog.DeleteEventSource("MySource");
            EventLog.Delete(logName);

            Console.WriteLine(logName + " deleted.");

注解

使用此方法从本地计算机中删除的 Source 注册。 DeleteEventSource 访问本地计算机上的注册表，并删除应用程序作为有效事件源的注册。

如果不再需要组件将条目写入该日志，则可以将其删除为事件的有效源。例如，如果需要将组件从一个日志更改为另一个日志，则可以执行此操作。由于源一次只能注册到一个日志，因此更改日志需要删除当前注册。

DeleteEventSource 仅删除注册到日志的源。如果要删除日志本身，请调用 Delete。如果只想删除日志条目，请调用 Clear。 Delete 和 DeleteEventSource 是 static 方法，因此可以在类本身上调用它们。无需创建实例来调用任一 EventLog 方法。

通过调用 Delete 删除日志会自动删除注册到该日志的源。这会使使用该日志的其他应用程序无法运行。

注意

如果源已映射到日志，并且你将其重新映射到新日志，则必须重新启动计算机才能使更改生效。

DeleteEventSource(String, String)

Source:: EventLog.cs

Source:: EventLog.cs

Source:: EventLog.cs

从指定的计算机上移除应用程序的事件源注册。

public:
 static void DeleteEventSource(System::String ^ source, System::String ^ machineName);

public static void DeleteEventSource (string source, string machineName);

static member DeleteEventSource : string * string -> unit

Public Shared Sub DeleteEventSource (source As String, machineName As String)

参数

source: String

应用程序在事件日志系统中用来注册的名称。

machineName: String

要从中移除注册的计算机名，对于本地计算机则为“.”。

例外

ArgumentException

machineName 参数无效。

- 或 -

指定计算机的注册表中不存在 source 参数。

- 或 -

您对事件日志的注册表项没有写访问权。

InvalidOperationException

无法删除 source，原因是在注册表中，source 的父注册表项不包含与其同名的子项。

示例

以下示例从指定计算机中删除源。该示例从其源中确定日志，然后删除该日志。

注意

多个源可能会写入事件日志。删除自定义日志之前，请确保没有其他源写入该日志。
