前言:開始開源計畫的創作。目的是開發一系列方便大家拿來即可使用的工具集合，希望能夠讓.net的生態更加豐富。該計畫采用MIT開源。並且如果參照nuget包，該計畫可以相容.net framework4.6.1以及以上的所有.nrt framework以及所有.net core或以上環境的所有.net版本。
Wesky.Net.OpenTools，開源地址： https://gitee.com/dreamer_j/open-tools.git
第一個nuget包版本，目前只有AES加密和解密，以及Byte數據轉換兩個功能。將來會繼續不斷完善、拓展。
先使用下第一個功能，AES加解密。
編寫一個簡單的控制台，， nuget包參照 WSesky.Net.OpenTools
編寫加密和解密功能
執行，得到加密和解密結果。
