在进行有关Snmpsharpnet的变成时遇到一个问题，当OctetString向时间转换时产生的是乱码。是因为snmpsharpnet并没有定义OctetString向datetime转换的函数。经过笔者的学习与实践找到了解决的办法。接下来以获得计算机上已安装程序的安装时间为例：

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Net;using SnmpSharpNet;//需要添加引用namespace 时间乱码问题{    class Program    {        static void Main(string[] args)        {            SimpleSnmp snmp = new SimpleSnmp("127.0.0.1", "public");            if (!snmp.Valid)            {                return;            }            Dictionary<Oid, AsnType> result = snmp.Walk(SnmpVersion.Ver2, ".1.3.6.1.2.1.25.6.3.1.5");//程序安装时间                        if (result == null)            {                return;            }            foreach (KeyValuePair<Oid, AsnType> kvp in result)            {                //Console.WriteLine(kvp.Value.ToString());      //如果是执行这一句就会发现是乱码结果                Console.WriteLine(parseDateAndTimeOctet((OctetString)kvp.Value));                            }        }        public static String parseDateAndTimeOctet( OctetString v )        {                        //OctetString                       byte[] bts = v.ToArray();                        byte[] format_str = new byte[128];   //保存格式化过后的时间字符串            int year;            int month;            int day;            int hour;            int minute;            int second;            //int msecond;                  year =year = bts[0] * 256  + bts[1];            month = bts[2];            day = bts[3];            hour = bts[4];            minute = bts[5];            second = bts[6];            //msecond = bts[7];            //以下为格式化字符串            int index = 3;            int temp = year;            for (; index >= 0; index--)            {                format_str[index] = (byte)(48 + (temp - temp / 10 * 10));                temp /= 10;            }            format_str[4] = (Byte)'-';            index = 6;            temp = month;            for (; index >= 5; index--)            {                format_str[index] = (byte)(48 + (temp - temp / 10 * 10));                temp /= 10;            }            format_str[7] = (Byte)'-';            index = 9;            temp = day;            for (; index >= 8; index--)            {                format_str[index] = (byte)(48 + (temp - temp / 10 * 10));                temp /= 10;            }            format_str[10] = (Byte)' ';            index = 12;            temp = hour;            for (; index >= 11; index--)            {                format_str[index] = (byte)(48 + (temp - temp / 10 * 10));                temp /= 10;            }            format_str[13] = (Byte)':';            index = 15;            temp = minute;            for (; index >= 14; index--)            {                format_str[index] = (byte)(48 + (temp - temp / 10 * 10));                temp /= 10;            }            format_str[16] = (Byte)':';            index = 18;            temp = second;            for (; index >= 17; index--)            {                format_str[index] = (byte)(48 + (temp - temp / 10 * 10));                temp /= 10;            }            //int i = 6;            //while (i >= 0)            //{            //    Console.WriteLine("{0}", bts[i]);            //    i--;            //}            return System.Text.Encoding.Default.GetString(format_str);// new String(format_str);        }    }}
