EventLog.LogNameFromSourceName(String, String) 方法

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

public static string LogNameFromSourceName (string source, string machineName);

static member LogNameFromSourceName : string * string -> string

Public Shared Function LogNameFromSourceName (source As String, machineName As String) As String

与注册表中的指定源关联的日志名称。

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。

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。

• Source
• MachineName
• Log
• SourceExists(String)
