使用 log4net (C#) 和 Oracle，我正在尝试创建一个自定义 ADO Appender，这样我就不需要使用配置文件。到目前为止我的代码

public static void CreateAppender()
{
    var hierarchy = (Hierarchy)LogManager.GetRepository();
    hierarchy.Root.RemoveAllAppenders();

    var ADOAppender = new AdoNetAppender();
   AddDateTimeParameterToAppender(ADOAppender, ":log_date", "log4net.Layout.RawTimeStampLayout");
   AddStringParameterToAppender(ADOAppender, ":thread", 255, "%thread");
   AddStringParameterToAppender(ADOAppender, ":log_level", 50, "%level");
   AddStringParameterToAppender(ADOAppender, ":logger", 255, "%logger");
   AddStringParameterToAppender(ADOAppender, ":message", 30000, "%message");

   ADOAppender.ConnectionType =
            "System.Data.OracleClient.OracleConnection, System.Data.OracleClient, Version=1.0.3300.0, Culture=neutral, PublicKeyToken=b77a5c561934e089";

   ADOAppender.CommandText =
            "INSERT INTO Log (Datetime,Thread,Log_Level,Logger,Message) VALUES (:log_date, :thread, :log_level, :logger, :message)";

   ADOAppender.ConnectionString = "data source=[db];User ID=[id];Password=[pass]";

   ADOAppender.BufferSize = 1;

  ADOAppender.ActivateOptions();

  log4net.Config.BasicConfigurator.Configure(ADOAppender);
}

public static void AddDateTimeParameterToAppender(AdoNetAppender appender, string paramName, string conversionPattern)
{
       var param = new AdoNetAppenderParameter { ParameterName = paramName, DbType = System.Data.DbType.DateTime, Layout = new Layout2RawLayoutAdapter(new PatternLayout(conversionPattern)) };
   appender.AddParameter(param);
}

public static void AddStringParameterToAppender(AdoNetAppender appender, string paramName, int size, string conversionPattern)
{
   var param = new AdoNetAppenderParameter
   {
      ParameterName = paramName,
      DbType = System.Data.DbType.String,
      Size = size,          
      Layout = new Layout2RawLayoutAdapter(new PatternLayout(conversionPattern))
   };
appender.AddParameter(param);

}

我没有收到任何异常，但没有数据被插入到数据库中。我几乎肯定它与参数有关，因为当我将所有值设置为 null 时，它会起作用。

有谁看到我做错了什么？我用谷歌搜索了很多，但我发现的例子都没有使用 ADO Appender。谢谢

我对 ADONetAppender 也有过类似的经历。你打开内部log4net调试了吗？我不记得我的问题的具体细节，但在打开调试后我能够弄清楚。

另外，我确定您有，但请确保您的项目中有“XmlConfigurator”行。

托比，感谢您的回复，我知道我做错了什么。添加 DateTime 参数时，当需要 RawTimeStampLayout() 时，我将布局设置为 Layout2RawLayoutAdapter。我需要替换Layout = new Layout2RawLayoutAdapter(new PatternLayout(conversionPattern))为Layout = new RawTimeStampLayout(). 我更新的 AddDateTimeParameterToAppender 方法看起来像这样..

public static void AddDateTimeParameterToAppender(AdoNetAppender appender, string paramName)
{
    var param = new AdoNetAppenderParameter
    {
        ParameterName = paramName, 
        DbType = System.Data.DbType.DateTime,
        Layout = new RawTimeStampLayout()
    };

    appender.AddParameter(param);
}
