+# 1024抽奖程序
+该程序使用了www.random.org提供的随机数API，它提供了真正的随机数序列，它通过大气噪音这种大自然的随机现象来产生随机数
+
+# 调试运行
+
+## 使用Visual Studio
+下载安装Visual Studio后打开项目文件Lottery.sln即可F5调试运行，若无法加载项目，则项目右键安装缺少的.NET Core依赖
+
+## 使用VS Code或其他文本编辑器
+以VS Code为例，该编辑器打开项目文件夹后（*.cs文件所在的文件夹），会自动安装C#的语法提示及调试器等插件，随后：
+1. 下载并安装[.NET Core SDK](https://dotnet.microsoft.com/download)
+
+2. 修改代码后，可以在VS Code中按F5运行或打开CMD或PowerShell定位到*.cs文件所在的文件夹，输入dotnet run即可运行
+
+# 修改
+计分规则位于Program.cs文件中并已注释可修改的部分，其他*.cs文件均为更新屏幕显示、Model、帮助类等
