登录日志管理功能--1

相关变量说明:
result = userSystem.SingIn( tempUserName , tempPassWord , out data ); 得到最后登录信息的值
UserID :DataRow row = data.Tables[ "表名" ].Rows[ 0 ];
userID = Convert.ToInt32( row[ Common.AdminCommon.UserData.USER_ID_FIELD ] );
在登录方法中加入AddLog(result,tempUserName,userID) 方法
LogData 类：

public class LogData : DataSet
{
public const string LOG_INFO_TABLE = "AdminLogTab"; //登录表名

public const string LOG_ID_FIELD = "ID"; //主键
public const string LOG_USER_ID_FIELD = "UserID"; //登录的用户编号
public const string LOG_USER_NAME_FIELD = "UserName"; //登录的用户名
public const string LOG_LOGIN_TIME_FIELD = "LogInTime"; //登录时间
public const string LOG_VALID_FIELD = "Valid"; //是否成功
public const string LOG_LOGOFF_TIME_FIELD = "LogOffTime"; //登出时间，暂时没用
public const string LOG_USER_IP_FIELD = "UserIp"; //登录的Ip
public const string LOG_REASON_FIELD = "Reason"; //原因

public LogData()
{
//
// TODO: 在此处添加构造函数逻辑
//

BuildTable();
}

private void BuildTable()
{
DataTable dt = new DataTable( LOG_INFO_TABLE );

DataColumnCollection dc = dt.Columns;

dc.Add( LOG_ID_FIELD , typeof( System.Int32 ));

dc.Add( LOG_USER_IP_FIELD ,typeof( System.String ));

this.Tables.Add(dt);
}
}

//得到IP

catch(Exception error)

//
