Log4Net在Sqlserver中初始化表结构

Log4net 使用不是即开即用，需要预先配置数据库，表，字段。

连接字符串示例（SQL server）为例

 这里包含了配置package，和字符串

这里需要的Package是System.Data.SqlClient，需要提前引入这个包才可以。Version不用动，我本地的System.Data.SqlClient是4.8.5，切换过去不好用，默认这个就可以了

<connectionType value="System.Data.SqlClient.SqlConnection,System.Data.SqlClient, Version=4.6.1.3, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
<connectionString value="Data Source=192.168.0.12;Initial Catalog=Steven.Test.DB,1433;Persist Security Info=True;User ID=sa;Password=密码替换这里;TrustServerCertificate=true" /

 配置的Sql

<commandText value="INSERT INTO SystemLog ([Date],[Thread],[Level],[Logger],[Message],[Exception]) VALUES (@log_date, @thread, @log_level, @logger, @message, @exception)" />

需要改表名就在上面sql里面改一下就好了，我这里是SystemLog

数据库自己建，或者对齐现有自己的，我这个sql的表结构是Navicat导出的，直接全部复制即可
