using Aliyun.Acs.Core.Exceptions;
using Aliyun.Acs.Core.Http;
using Aliyun.Acs.Core.Profile; 
using Newtonsoft.Json;
using System; 
using System.Windows.Forms;

    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e1)
        {
            IClientProfile profile = DefaultProfile.GetProfile("cn-hangzhou", "LTAI4FwHgQKtSdTnv3rf9bBo", "SaxyW25aCuqVIv2DCPjrf4dHByIvD3");
            DefaultAcsClient client = new DefaultAcsClient(profile);
            CommonRequest request = new CommonRequest();
            request.Method = MethodType.POST;
            request.Domain = "dysmsapi.aliyuncs.com";
            request.Version = "2017-05-25";
            request.Action = "SendSms";
            // request.Protocol = ProtocolType.HTTP;
            request.AddQueryParameters("PhoneNumbers", "18150886330");
            request.AddQueryParameters("SignName", "中交华安");
