@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; using System.Collections.Generic; using System.Linq; using System.Web; 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(); } } }
