这很容易，亲爱的，
首先，您必须在一个变量中声明您的api ref网站Url，然后将所有所需的变量通过Url传递给

字符串网址，mno，短信；

urls =" www.smsjunction.com?m=";
mno = TextMobileno.Text.ToString();
sms = TextSms.Text.ToString();

urls = urls + mno +''，sms =""+ sms;

Response.Redirect(urls);

It is very easy dear,
at first you have to declare your api ref website Url in a variable and pass all needed variable through Url like

String urls, mno, sms;

urls= "www.smsjunction.com?m=''";
mno=TextMobileno.Text.ToString();
sms=TextSms.Text.ToString();

urls=urls+mno+"'',sms=''"+sms;

Response.Redirect(urls);
