@log_ip为客户端IP字段名称，名字可以自己取，INSERT语句顺序匹配上就行

配置字段自定义处理程序：

<parameter>
        <parameterName value="@log_ip"/>
        <dbType value="String"/>
        <size value="50"/>
        <layout type="Electric.WebUI.ConsoleLog.IPatternLayout">
          <conversionPattern value="%log_IP"/>
        </layout>
</parameter>

parameterName：我们定义的字段名称

dbType：默认String

layout：处理程序的命名空间

获取客户端IP处理程序:

using System.Text;
 
namespace Electric.WebUI.ConsoleLog
{
 
    public class LogMessage
    {
        public LogMessage()
        {
            Computer cp = Computer.Instance;
            Message = "";
            IP = cp.IpAddress;
        }
        public LogMessage(string message)
            : this()
        {
            Message = message;
        }
        public string IP { get; set; }
 
        public string Message { get; set; }
        public override string ToString()
        {
            return Message.ToString();
        }
    }
