1.log4net官網(wǎng)配置相關(guān)，創(chuàng)建數(shù)據(jù)庫

http://logging.apache.org/log4net/release/config-examples.html

CREATE TABLE [dbo].[tbl_LogInfo]( [ID] [int] IDENTITY(1,1) NOT NULL, [LogTime] [datetime] NOT NULL, [Thread] [nvarchar](max) NOT NULL, [LogLevel] [nvarchar](max) NULL, [Logger] [nvarchar](max) NULL, [Message] [nvarchar](max) NULL, [Exception] [nvarchar](max) NULL）

　　配置項(xiàng)

<configuration> <log4net><appender name="ADONetAppender" type="log4net.Appender.ADONetAppender"><bufferSize value="10"/><connectionType value="System.Data.SqlClient.SqlConnection, System.Data, Version=1.0.3300.0, Culture=neutral, PublicKeyToken=2sdfg57345c5619dsfsdf"/><commandText value="INSERT INTO tbl_LogInfo ([LogTime],[Thread],[LogLevel],[Logger],[Message],[Exception]) VALUES (@log_date, @thread, @log_level, @logger, @message, @exception)"/><parameter><parameterName value="@log_date"/><dbType value="DateTime"/><layout type="log4net.Layout.RawTimeStampLayout"/></parameter><parameter><parameterName value="@thread"/><dbType value="String"/><size value="255"/><layout type="log4net.Layout.PatternLayout"><conversionPattern value="%thread"/></layout></parameter><parameter><parameterName value="@log_level"/><dbType value="String"/><size value="50"/><layout type="log4net.Layout.PatternLayout"><conversionPattern value="%level"/></layout></parameter><parameter><parameterName value="@logger"/><dbType value="String"/><size value="255"/><layout type="log4net.Layout.PatternLayout"><conversionPattern value="%logger"/></layout></parameter><parameter><parameterName value="@message"/><dbType value="String"/><size value="4000"/><layout type="log4net.Layout.PatternLayout"><conversionPattern value="%message"/></layout></parameter><parameter><parameterName value="@exception"/><dbType value="String"/><size value="2000"/><layout type="log4net.Layout.ExceptionLayout"/></parameter></appender><root><level value="ALL"/><appender-ref ref="LogFileAppender"/><appender-ref ref="ADONetAppender"/></root></log4net> </configuration>
