现在很多网站都是短信发送的功能，怎么实现的呢。对于个人站长来说的话，通过使用SMS短信通API接口相对比较划算和简单。那怎么实现呢，步骤如下：

1. 从网上（http://sms.webchinese.cn/）申请账号，记住用户名，密码会发到手机上，这仅是登陆密码。注册后会送5条短信、和3条彩信的发送量。

2.查看SMS短信通API下行接口（http://sms.webchinese.cn/api.shtml），然后获取秘钥，其实就是加密后的登录密码。开始敲代码，相关代码如下：

using System;using System.Collections.Generic;using System.IO;using System.Linq;using System.Net;using System.Text;using System.Web;namespace Y_PostSms{    public class YMethod    {        PRivate string THE_UID = ""; //用户名        private string THE_KEY = ""; //接口秘钥        /// <summary>返回UTF-8编码发送接口地址</summary>        /// <param name="receivePhoneNumber">目的手机号码（多个手机号请用半角逗号隔开）</param>        /// <param name="receiveSms">短信内容，最多支持400个字，普通短信70个字/条，长短信64个字/条计费</param>        /// <returns></returns>        public string GetPostUrl(string smsMob, string smsText)        {            string postUrl = "http://utf8.sms.webchinese.cn/?Uid=" + THE_UID + "&key=" + THE_KEY + "&smsMob=" + smsMob + "&smsText=" + smsText;            return postUrl;        }        /// <summary> 发送短信，得到返回值</summary>        public string PostSmsInfo(string url)        {            //调用时只需要把拼成的URL传给该函数即可。判断返回值即可            string strRet = null;            if (url == null || url.Trim().ToString() == "")            {                return strRet;            }            string targeturl = url.Trim().ToString();            try            {                HttpWebRequest hr = (HttpWebRequest)WebRequest.Create(targeturl);                hr.UserAgent = "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)";                hr.Method = "GET";                hr.Timeout = 30 * 60 * 1000;                WebResponse hs = hr.GetResponse();                Stream sr = hs.GetResponseStream();                StreamReader ser = new StreamReader(sr, Encoding.Default);                strRet = ser.ReadToEnd();            }            catch (Exception ex)            {                strRet = null;            }            return strRet;        }        /// <summary>确认返回信息 </summary>        public string GetResult(string strRet)        {            int result = 0;            try            {                result = int.Parse(strRet);                switch (result)                {                    case -1:                        strRet = "没有该用户账户";                        break;                    case -2:                        strRet = "接口密钥不正确,不是账户登陆密码";                        break;                    case -21:                        strRet = "md5接口密钥加密不正确";                        break;                    case -3:                        strRet = "短信数量不足";                        break;                    case -11:                        strRet = "该用户被禁用";                        break;                    case -14:                        strRet = "短信内容出现非法字符";                        break;                    case -4:                        strRet = "手机号格式不正确";                        break;                    case -41:                        strRet = "手机号码为空";                        break;                    case -42:                        strRet = "短信内容为空";                        break;                    case -51:                        strRet = "短信签名格式不正确,接口签名格式为：【签名内容】";                        break;                    case -6:                        strRet = "ip限制";                        break;                    default:                        strRet = "发送短信数量：" + result;                        break;                }            }            catch (Exception ex)            {                strRet = ex.Message;            }            return strRet;        }    }}
