【.aspx.cs】

string shouji = "";
string templateid = "181ed0353b8341808620a1ed871793b5";

shouji = gelian.Value.Trim();
string yzm = IdentifyingCode.GenCode(4);
Boolean bret = SMSafd.sendSMS(shouji, templateid, yzm);

动态获取验证码：
public static string GenCode(int num)
{
string[] source = { "0", "1", "2", "3", "4", "5", "6", "7", "8", "9", "A", "B", "C", "D", "E", "F", "G", "H", "I", "J", "K", "L", "M", "N", "O", "P,", "Q", "R", "S", "T", "U", "V", "W", "X", "Y", "Z" };
string code = "";

//获取验证码
for (int i = 0; i < num; i++)
{
code += source[rd.Next(0, source.Length)];

}
//返回产生的验证码
return code.Replace(",", "");
}
