Here's how to get its 3 access keys: clientId, clientSecret, refreshToken

Note: the names you enter here don't really matter.

0. Visit https://console.developers.google.com/apis/api/chromewebstore/overview
1. Create a project:

poychang

using System.IO;
using System.Collections.Generic;

/// <summary>
/// 取得指定往下第幾層的資料夾路徑
/// </summary>
/// <remarks>使用此方法只取指定層數的資料夾路徑，避免子資料夾路徑太深、太多造成效能問題</remarks>
/// <param name="path">根路徑</param>
/// <param name="depth">第幾層的資料夾路徑</param>
/// <returns></returns>

Web 所面臨的挑戰

後端 MVC

約在 2015 年，主流的 Web 開發架構仍以後端 MVC 為主：

void Main()
{
    DemoMultiplyTimeSpan();
    DemoTimePlusMultiplyTimeSpan();
}

// Define other methods and classes here
void DemoMultiplyTimeSpan()
{
    var duration = TimeSpan.FromMinutes(1);

void Main()
{
    var rawString = "Hi, my name is Poy Chang. I am currently conducting a project of enterprise app through Angular and .NET Core. As a developer and designer, I believe that keep learning and practicing is the most important thing. Reading, watching movies and traveling are also my favorites in my life.";

    var zippedString = GZipCompressString(rawString);
    Console.WriteLine($"壓縮結果：\r\n{zippedString}\r\n");

    var unzipString = GZipDecompressString(zippedString);
    Console.WriteLine($"解壓縮後：\r\n{unzipString}\r\n");
