SMS发送WapPush

首先要将这两个字段设置为"1"
tp_Pid = 1;
tp_Udhi = 1;短信内容编码要设置为:4也就是二进制MessageFmt=4;
然后对要发送的WapPush进行编码

 static private byte[] WapPushUrl(string href)
        {
            href = href.ToLower().Replace("http://", "");
            byte[] tmp = new byte[href.Length];
            tmp = System.Text.Encoding.UTF8.GetBytes(href);
            return tmp;
        }
        static private byte[] WapPushContent(string text)
        {
            byte[] tmp = new byte[text.Length];
            tmp = System.Text.Encoding.UTF8.GetBytes(text);
            return tmp;
        }
        //转换为16进制
        private string bytesToHexStr(byte[] abyte0)
        {
            if(abyte0 == null)
                return "";
            System.Text.StringBuilder stringbuffer = new System.Text.StringBuilder(abyte0.Length * 3);
            for(int i = 0; i < abyte0.Length; i++)
            {
                stringbuffer.Append(System.Convert.ToString(abyte0[i] & 0xff,16));
            }
            return stringbuffer.ToString();
        }

        public string GetWapString()
        {
            System.Text.StringBuilder tmp = new StringBuilder();
            tmp.Append("0B05040B8423F0000303010129060603AE81EA8DCA02056A0045C6080C03");
            tmp.Append(bytesToHexStr(WapPushUrl(Href)));
            tmp.Append("000103");
            tmp.Append(bytesToHexStr(WapPushContent(Text)));
            tmp.Append("000101");

            return tmp.ToString().ToUpper();
        }
