前言:开始开源项目的创作。目的是开发一系列方便大家拿来即可使用的工具集合，希望能够让.net的生态更加丰富。该项目采用MIT开源。并且如果引用nuget包，该项目可以兼容.net framework4.6.1以及以上的所有.nrt framework以及所有.net core或以上环境的所有.net版本。
Wesky.Net.OpenTools，开源地址：https://gitee.com/dreamer_j/open-tools.git
第一个nuget包版本，目前只有AES加密和解密，以及Byte数据转换两个功能。将来会继续不断完善、拓展。
先使用下第一个功能，AES加解密。
编写一个简单的控制台，，nuget包引用 WSesky.Net.OpenTools
编写加密和解密功能
运行，得到加密和解密结果。
