C# POST using WebRequest

標題：C#使用WebRequest POST後取得回傳資料
C# (Program.cs)：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Net; //WebRequest WebResponse
using System.IO; //Stream

public class Global
{
    public static string server = "http://127.0.0.1:1337";
}

namespace WebPostRequest
{
    class Program
    {
        static string login(string email, string password)
        {
            //宣告送出資料
            string param = "email=" + email + "&password=" + password;
            byte[] byteArray = Encoding.UTF8.GetBytes(param);

            //Request資料
            WebRequest request = WebRequest.Create(Global.server + "/login");
            request.Credentials = CredentialCache.DefaultCredentials;
            ((HttpWebRequest)request).UserAgent = ".NET Framework Example Client";
            request.Method = "POST";
            request.ContentLength = byteArray.Length;
            request.ContentType = "application/x-www-form-urlencoded";

            //處理資料流
            Stream dataStream = request.GetRequestStream();
            dataStream.Write(byteArray, 0, byteArray.Length);
            dataStream.Close();

            //Response資料
            WebResponse response = request.GetResponse();
            string rawJsonString = new StreamReader(response.GetResponseStream()).ReadToEnd();
            response.Close();

            return rawJsonString;
        }

        static void Main(string[] args)
        {
            Console.WriteLine( login("test@gmail.com", "abcd1234") );

            Console.WriteLine("\r\nPress enter key to continue....");
            Console.Read();
        }
    }
}

說明：
簡單使用WebRequest POST送出email、password後回傳字串資料的作法。
