获取指定的源注册到的日志的名称。
public:
static System::String ^ LogNameFromSourceName(System::String ^ source, System::String ^ machineName);public static string LogNameFromSourceName (string source, string machineName);static member LogNameFromSourceName : string * string -> stringPublic Shared Function LogNameFromSourceName (source As String, machineName As String) As String参数
- source
- String
事件源的名称。
- machineName
- String
要从中删除日志的计算机名称，对于本地计算机则为“.”。
返回
与注册表中的指定源关联的日志名称。
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。 在删除自定义日志之前，请确保没有其他源写入该日志。

{

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 );
}

// Create the event source to make next try successful.

注解
事件源指示记录事件的内容。 它通常是应用程序的名称，或者应用程序子组件的名称（如果应用程序很大）。 应用程序和服务应写入应用程序日志或自定义日志。 设备驱动程序应写入系统日志。
创建一次只能写入一个日志的新源时，系统会将应用程序注册到事件日志中，作为有效的条目源。 属性 Source 可以是任何字符串，但名称不能由计算机上的其他源使用。 尝试创建重复 Source 值会引发异常。 但是，单个事件日志可以有许多不同的源写入其中。
