1.log4net官网配置相关，创建数据库

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）

　　配置项

 <configuration>
<log4net>
    <appender name="ADONetAppender" type="log4net.Appender.ADONetAppender">

      <connectionType value="System.Data.SqlClient.SqlConnection, System.Data, Version=1.0.3300.0, Culture=neutral, PublicKeyToken=2sdfg57345c5619dsfsdf"/>

      </parameter>
    </appender>
    <root>

        }
        private static void ConfigureLog4Net()
        {
            Hierarchy hierarchy = LogManager.GetRepository() as Hierarchy;
            if (hierarchy != null && hierarchy.Configured)
            {
                foreach (IAppender appender in hierarchy.GetAppenders())
                {
                    if (appender is AdoNetAppender)
                    {
                        var adoNetAppender = (AdoNetAppender)appender;
                        adoNetAppender.ConnectionString =ConfigurationHelper.GetConnectionString("你配置在配置文件中的数据库名称");
                        adoNetAppender.ActivateOptions(); //Refresh AdoNetAppenders Settings
                    }
                }

实际运用

 catch (Exception ex)
            {
                LogHelper.AddErrorLog("Login", this.GetType(), ex);
            }
