C#操作SQLite教程，使用NuGet添加SQLite的引用-C#-天下网吧

新需求：

给网维制作一个修复火箭下载器工具。技术原理根据天下网吧文章：

批处理卸载/安装网吧火箭下载器服务，修复无法下载更新游戏问题

要求友好的操作界面和提示。

需求分析：

根据技术原理文章可以看到，实现这个功能很简单，一个就是启动/停止服务，一个是运行外部命令来安装/卸载火箭下载器的服务。

实现这个功能，C#相关代码资源比较多。

执行效果：

核心代码：

using System.Diagnostics;
using System.ServiceProcess;
using System.Diagnostics;
