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。

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>
using namespace System;
using namespace System::Diagnostics;
using namespace System::Threading;
int main()
{
String^ logName;
if ( EventLog::SourceExists( "MySource" ) )
{
// 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 -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.
EventLog::CreateEventSource("MySource", "MyLog");
}
}

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.");
}

{
// Create the event source to make next try successful.
EventLog.CreateEventSource("MySource", "MyLog");

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:

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
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。
